How DNA Become My Traits
How did the info in my DNA become my traits? This is a question that has been asked by many over the course of history.To answer this question we need to answer three essential questions, the first, how did we get our DNA, how did we go form one cell to trillions, and how did DNA become our traits. There is one essential driver to all of this, DNA, to understand DNA, we need to know what DNA is. DNA is two strands that contain genetic information in four bases, adenine, guanine, cytosine and thymine. DNA is located in the cell nucleus and is found in all multi- cell organisms. To begin with, how did the DNA become and get in our bodies. It all starts with the sperm and the egg, gametes. A gamete is a reproductive cell for a male or female. …show more content…
The cells prepares to divide by growing in size and prepares for DNA synthesis, when it enters the cell cycle. The cell cycle contains 5 phases, growing in size and preparing for DNA synthesis is the in the G phase and the G1 phase, next the cells then goes onto the S phase, this is where the DNA is replicated. Between the G1 and S phase is a check point where the cell cycle checks if the cell is proper to be divided. After the DNA is copied, the DNA copy and the cell goes through another checkpoint. If the cell does not pass through the checkpoint successfully the cell cycle will do one of the two, either try to repair the error in the cell or tell the cell to do apoptosis, the killing or destruction of the cell to prevent the cell from creating any other errors or messed up cells. The cell then move through the rest of the cell cycle and goes through the G2 phase where the cell prepares for mitosis. Mitosis is the process of division of cells in the cell cycle known as the M phase, this is how the cells in our body divides and grow. As the cell continues through the cell cycle to the M phase, here the cells goes through the stages of Mitosis and as the result it produces two diploid cells. Not every cell goes through Mitosis immediately, the cells need to either be told to prepare for division or it senses the cell next to it is missing and needs to divide to

    DNA stands for Deoxyribonucleic acid and looks like a spiral. The spiral is also known as a double helix. The strands are made up of our genetic information, composed of genes and chromosomes. There are four bases divided among purines and pyrimidines. On the purines there are Adenine (A) and Guanine (G). On the pyrimidines there are Cytosine (C) and Thymine (T). The base pairs are Adenine and Thymine (A-T) and Cytosine and Guanine (C-G). DNA is found in the nucleus of every human cell. Humans have 46 chromosomes. When a cell reproduces, the chromosomes get copied and distributed to each offspring.…

    Eukaryotic cells go through Interphase and Mitosis. Interphase is further subdivided into 3 stages, G1 (first gap), S (synthesis of DNA), and G2 (second gap). In all 3 sub phases cell growth happens and organelles like mitochondria are replicated. DNA, however, is only synthesized during the S phase. DNA replication is started by Helicase which unwinds the double helix at replication forks. Topoisomerase is used to loosen the tension at the ends of the bubble, in order to correct for over winding ahead of the replication forks. Primase then synthesizes an RNA primer which the DNA polymerase III will use to lay down bases, synthesizing a new strand. DNA polymerase I will then remove the primer and DNA Ligase will join ends of DNA synthesized from different replication forks. Because DNA can only synthesize from 5'->3', there is a leading strand and lagging strand which creates Okazaki fragments that are later joined together by DNA Ligase. After DNA is replicated proofreading enzymes will check and repair any mistakes that occurred during replication. After S phase is the G2 phase where the cell grows even larger. G2 is followed by mitosis, which is subdivided into 5 parts: prophase, metaphase, anaphase, telophase, and cytokinesis. In prophase, chromatin condenses and the nucleoli disappears. What we know as chromosomes, which consist of two identical sister chromatids joined together at centromers, begin to appear. Mitotic spindle is formed and the centromers start moving to opposite poles, propelled by the lengthening microtubules that they shoot out. In metaphase, the longest stage of mitosis, the chromosomes line up on the metaphase plate and the centromeres have already migrated to opposite poles.…

    DNA is one of the nucleic acids information-containing molecules in the cell (ribonucleic acid, or RNA, is the other nuclei c acid). DNA if found in the nucleus of every human cell. The information is DNA: guides the cells (along with RNA) in making new proteins that determine all of our biological traits. DNA gets passed (copies) from one generation to the next. DNA in a cell is really just a pattern made up of four different parts called nucleotides. Image a set of blocks that has only four shapes, or an alphabet that has only four letters. DNA is a long string of these blocks or letters.…

    Have you ever asked yourself, exactly what is DNA and why is it so important? DNA stands for Deoxyribonucleic Acid and is found in every living thing. We inherit DNA from our parents, half from our mothers and half from our fathers. DNA is made up of sugars, bases, and phosphates and comes in the structure of a double helix which looks like a spiral staircase (Craig Freudenrich, 2007). DNA is found in the genes which are housed in chromosomes. Humans have 46 chromosomes; however, the amount of chromosomes varies from specie to specie. Except in the case of identical twins, DNA is unique…

    The cell cycle begins in the G1 phase. This phase is where the cell carries out its normal functions. During this phase, however, the cell passes through a vital check point before it enters the synthesis phase. Synthesis, by definition, means combining parts to make a whole. During this stage the cell makes a copy of its DNA. By the end of the “S” stage the nucleus of the cell has two complete sets of DNA. During the G2 stage cells continue normal functions and have additional growth. This stage also contains a check point to make sure all is well with the cell before continuing to the next stage, mitosis. Mitosis is where the cell’s nucleus and its contents divide. Through this stage the nuclear membrane dissolves and DNA condenses around…

    DNA consists of two polynucleotide chains and these nucleotides consist of a deoxyribose sugar, a nitrogenous base and a phosphate group. The bases are Adenine, Cytosine, Guanine and Thymine. The sequence of these bases on DNA determines the structure of these proteins. A gene is a sequence of bases which codes for a single polypeptide. Chromosomes carry these genes and these genes come in specific forms called an allele which is how living organisms vary from each other. For example, humans are made up of an XY or XX chromosome. Females are XX and males are XY, however in some animals their sex is determined by the ZW sex-determination…

    What makes the human genome so incredibly fascinating? Is it the thousands of genetic sequences of DNA (deoxyribonucleic acid) or the fact that all life is specified by genomes? Or could it be the fact that a genome contains the building blocks of life and without it, life would not exist as it is at this very moment? These are the types of questions that spark the interest in the human genome and genetic research. From the beginning of time, scientists have always shown great interest in the whereabouts of the human species, being that the human species are the most complex organisms living to this present day. Who wouldn’t want to know more about oneself, especially if it could be beneficial to obtain that knowledge? Why are human beings so complex? Why do humans behave the way they do? Why do individuals have different skin colors or hair or heights and sizes? All of these questions and more are answered through the help of genetic research.…
