Role of Molecular Biology in the 21st Century
1…………….ROLE OF MOLECULAR BIOLOGY IN THE 21ST CENTURY
THE STATEMENT: Molecular biology of the 21st century, which says that the science devoted to elucidating the structure and function of genomes. On the other hand, the major advances gave rise to central dogma of molecular biology, comprising the three major processes in the cellular utilization of genetic information. The first is replication, the copying of parental DNA to form daughter DNA molecules with identical nucleotide sequences. The second is transcription, the process by which parts of the genetic message encoded in DNA are copied precisely into RNA. The third is translation, whereby the genetic message encoded in messenger RNA is translated on the ribosomes into a polypeptide with a particular sequence at amino acids.
Some persons have spoken in favour of the discovery of the structure of DNA as a helical duplex of nucleotide polymers by James Watson and Francis Crick in 1953 has permitted life scientists to re-examine most biology phenomenon using the research tools developed by molecular biologists and biochemistry. First of all, he reminded us of the fact that system biology is not really new. As early as in the 1950s and 1960s, a scientific field with the same intention appeared on the horizon. Norbert Wiener, who was among the physicists who pioneered this discipline, defined it as cybernetics. During the last decades, the publication frequency in the field of cybernetics has dropped considerably, and Niehrs predicts that, in the 21st century, system biology will take the place of cybernetics.
Niehrs own research is focused on the regulation of Synexpression Group (SG) i:e clusters of co-expressed genes that participate in a biological process. Synexpression Groups functions in diverse processes such as cell signaling, cell cycle and in protein and lipid biosynthesis. They can be identified by their expression patterns in various eukaryotes.
Let us consider the quality of DNA consisting of two

    TRANSCRIPTION: Transcription is the process of which DNA matches corresponding RNA bases, Transcription is located in the Nucleus, and the only type of RNA that is involved in Transcription is mRNA, and the purpose is so that the code can get out of the Nucleus, mRNA is also made through Transcription, It also takes information that doesn't directly make proteins but it helps makes codes for the production of proteins, DNA Transcription consist of 4 nucleotide bases, Adenine, Thymine, Cytosine, Guanine. Transcription also unwinds the strand of DNA and the RNA comes in and matches then becomes a single strand. The only thing that changes during this process is the Thymine gets replaced with Uracil.…

    The flow of information starts with transcription. Within transcription, the DNA molecule holds a nucleotide sequence called the promoter that the RNA polymerase attaches to and begins the RNA synthesis. Through the process of transcription, the RNA strand becomes longer and finally detaches from the DNA strand, wherein the two DNA strands come back together forming the previously continuous strand. At this point the RNA turns…

    The flow of information from gene to protein is based on the triplet code. The genetic instructions for the amino acid sequence of a polypeptide chain are written in DNA and RNA as a series of three-base words called codons. The three-base codons in DNA are transcribed into complementary three-base codons in RNA, and then the RNA codons are translated into amino…

    Transcription goes through three steps: (1) initiation that starts at the beginning of a gene, (2) elongation is where the body of the gene metaphoric into growth, and (3) termination stage where a gene dies. The significance of the first and last codons relies on the stages of a gene’s life span. Everything has a point in life where it starts and ends. The importance of genetics is to understand the transformation it goes through.…

    The main goal of synthetic life is to recreate life from nonliving components. Synthetic biology attempts to create new biological molecules and even novel living species capable of carrying out a range of important medical and industrial functions. From manufacturing pharmaceuticals to detoxifying polluted land and water. In medicine, it offers prospects of using designer biological parts as a starting point for an entirely new class of therapies and diagnostic tools (Nature). One of the aims of synthetic biology is to understand the many interactions in living cells and by fabricating biological systems and understanding how they function. Since natural biological systems are so complex, scientists in this field start by making simple synthetic systems and then studying what factors affect that fabricated system. In this way, the "design" of future synthetic systems can be continually improved as well as gaining a deeper insight to the complex interactions within those biological systems. Thus, the idea is to understand the complex interactions in living systems by building and designing them from bottom to top. Originally, this was the aim of the field of systems biology, which aims to understand the complexity of living systems by taking all the biological interactions as a whole and then putting forth models in order to describe how they give rise to intricate…

    “Cancer is mitosis gone wild!” screeched a nasally-driven voice. Clad in plaid pants and coke-bottle glasses, a 75-year old man standing at only 5 and a half feet tall, [Mr. Jones] tried to explain uncontrollable cell division in modern terms. Students could hear his resonating voice from miles away, and it is that voice that gave me my first taste of the art of genetics. Mr. Jones’ spritely energy sparked my fascination with the most phenomenal language on earth that every living creature shares. Constructing the double helix with pipe cleaners and jelly beans, memorizing how transcription occurs or cutting and pasting karyotypes together constituted only a tiny fraction of the information Mr. Jones instilled in me.…

    By definition of dictionary.com gene is defined as the basic physical unit of heredity. a gene is a linear sequence of nucleotides that makes part of a segment called DNA. Deoxyribonucleic acid (DNA) is a nucleic acid that contains genetic codes in the development and functioning of all known living organisms. DNA provides a a linear sequence of nucleotides along a segment of DNA that provides very important codes that make up humans for who and what they are. The process of gene expression is a process that is continuously regulated by the cells nucleus in the regulation of proteins. However, this long coding process has to start somewhere. As I said earlier this function is carried out by a cells nucleus where membranes regulate the function of what enter and leaves the cells through a wide range of mechanisms. On the outside of the membrane, certain receptors are triggered to certain proteins inside the cells cytoplasm. A certain receptor is made that enters the cells nucleus reacting with the DNA, in desire for the expressed gene. Expression is complex process upon which there are many steps which undergo. One is transcription. This is where a copy of one side of genetic information is made to be stored in DNA. Upon starting transcription, proteins are made to read the DNA called rRNA. A second process is involved called splicing. This is where unnecessary parts of RNA are made to create the gene the protein has sent out to make. After all necessary changes have been made to RNA, mRNA is decoded by the ribosome to produce a specific amino acid chains, or polypeptide, that will later fold into an active protein. This sets up the last set of what it takes to make the necessary protein. Posttraslational modification is the chemical modification of a protein after translation synthesis and is the final result of the process gene expression, which leads to the expression of…

    “Biotechnology is the use of living things to make or change products. It is both an ancient art and a modern science with applications across different sectors.” – CSIRO. Biotechnology contains the special chemicals of living cells, from single-celled bacteria and yeasts, to multi-cellular organisms for human purpose. The word ‘biotechnology’ is modern though humans have been using biotechnology to staple foods and beverages for a very long time. It can be used to help cure several different diseases though the same biotechnology can also increase chances of abnormalities to humans. Biotechnology is a huge influence for the future of humans and plays an important role in sustaining human life. The three popular aspects of biotechnology are IVF, Gene Therapy and Cloning and will be covered in relation to the future of us humans.…

    During the early1960s, there was great progress being made in beginning to understand the structure of genes and the mechanisms of their replication, expression, and regulation in prokaryotes and the viruses that began to infect them (Berg 2010). However at the time it was still unknown as to whether or not these findings applied to eukaryotes. This is because the tools used at the time for exploring genetic properties were not fit for the task.…
