PURPOSE OF DNA
Nachila Ortiz and Micheala Desena
What Is DNA ?
- DNA's main role of in the cell is the long-term storage of information.
- a self-replicating material present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information.
- The purpose of DNA is to not only control development, but it is also pass down information as well.
Look how the DNA works.
What does the DNA do?
- Major function of DNA is encode the sequence of amino acid resides in proteins, using the genetic code.
- DNA is stored inside the cell nucleus while in prokaryotes such as bacteria and achaea, the DNA is in the cell's cytoplasm.
- The genetic code is the set of rules by which information encoded within genetic material is translated into proteins by living cells.
- The genetic code can be expressed as either RNA codons or DNA codons.
- DNA sequencing has become so rapid and because most genes are now being discovered at the level of DNA before they are discovered as mRNA or as a protein product, it is extremely useful to have a table of codons expressed as DNA.
- A nucleotide is one of the structural components, or building blocks, of DNA and RNA
- A nucleotide consists of a base
- The DNA nucleotide are adenine, thymine, guanine, and cytosine
- C, T, and U are called pyrimidines and each has a single nitrogen-containing ring. A and G are called purines and each has two nitrogen-containing rings.
- DNA replication begins with the "unzipping" of the parent molecule as the hydrogen bases between the base pairs are broken.
- DNA replication is the process of producing two identical replicas from one original DNA molecule.
- Biological process occurs in all living organisms
- Chromosomes must be replicated, divided, and passed successfully to their daughter cells
