DNA: DNA is a double-stranded nucleic acid that contains the genetic information for cell growth‚ division‚ and function. DNA‚ or deoxyribonucleic acid‚ is the hereditary material in humans and almost all other organisms. Most DNA is located in the cell nucleus but a small amount of DNA can also be found in the mitochondria .The information in DNA is stored as a code made up of four nitrogen bases which are adenine (A)‚ guanine (G)‚ cytosine (C)‚ and thymine (T). these nitrogen bases are bind with

DNA Assignment Keshia Yeates BIOLOGY 4U 1. DNA molecule with a length of 2m can fit inside a nucleus that is invisible by the naked eye by coiling around itself several times. It continues to coil even more (Supercoiling)‚ arranging itself on histones‚ which are proteins. 2. Nitrogen bases determine the traits of living organisms by coding the 20 amino acids. The order of the amino acids determines what protein is made; therefore‚ proteins are the makeup of all living organisms. Proteins regulate

Review 2: Text DNA is a very special and important molecule that is in our life‚ DNA is found in the nucleus. DNA stores the data needed to make poly peptides‚then data in a nucleic acid is transferred to messenger RNA‚ which escapes the nucleus into a protein. According to the DNA and protein article DNA is used in many things but DNA is used to make pol-peptides. They are another word for proteins. When a cell makes a protein the direction are resembled from the part of an DNA. DNA strand and transcript

DNA Transcription The process of transcription is where a copy of a gene is made within DNA to use as RNA. It is located in the nucleus of eukaryotes and in the nucleoid of prokaryotes. DNA stores information encoded in a genetic code. The code consists of four letters and they are T (thymine)‚ G (guanine)‚ A (Adenine)‚ and C (cytosine). One gene codes for on protein. RNA is a molecule that copies information that is coded in another genetic code. This code also consists of the same four

Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. DNA is a polymer‚ which is a chemical compound or a mixture of compounds consisting of repeating structural units. These repeating structures are created through polymerization. The monomer‚ meaning one part‚ units of DNA are nucleotides. Each nucleotide consists of a five carbon sugar‚ also known as deoxyribose‚ and nitrogen containing base attached to the sugar

Forensic DNA Evidence DNA has become one of the most accurate tools used in law enforcement in determining guilt or innocence. DNA is different in all people it is our “genetic blueprint.” DNA is so significant to law enforcement because DNA left at a crime scene can be collected and tested to see if there is a match. It is unique because it ensures accuracy and fairness. The initial use of DNA began in Britain in 1986; the FBI used it for the first time in the United States two years

DNA Replication DNA replication is a biological process that occurs in all living organisms and copies their DNA. The initiation of DNA replication starts with two steps. First an initiator protein unwinds a short stretch of the DNA double helix. Then a protein called helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands‚ pulling apart the two strands. DNA replication starts when one double-stranded DNA molecule produces two identical copies of the molecule

DNA‚ or deoxyribonucleic acid‚ is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA)‚ but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA). The information in DNA is stored as a code made up of four chemical bases: adenine (A)‚ guanine (G)‚ cytosine (C)‚ and thymine (T). The order‚ or sequence‚ of

Computing Computer Science & Engineering DNA Computing Computer chip manufacturers have discovered that sooner or later the physical speed and miniaturization limits of silicon chip is bound to hit a wall‚ therefore they need a new material to produce faster computing speed with fewewr complexity. DNA‚ the material are genes are made of‚ is being used to built the next generation of microprocessor. A nascent technology that uses DNA molecules is to build computers that are faster
