What does DNA do?
DNA carries all of the information about your personal characteristics, that information is controlled by proteins, and each protein in encoded by a gene.
DNA also controls a lot of other things, such as heredity. In heredity, DNA is the reason you like the way you do and have the traits of parents. Genes in the DNA pass these traits from parent to offspring, or child. Then the DNA replicates during mitosis and meiosis and keeps doing that until you are made.
Second, replication, DNA replication occurs in the cytoplasm or nucleus, depending on whether or not it is a eukaryotic cell or a prokaryotic cell. The DNA inside the cell must unwind the double helix and allow enzymes to attach and create a new strand of DNA, so you will wind up with a new and old half of the DNA molecule.
Lastly is protein production, the DNA is made of a chain of nucleotide bases, ribosomes reads the codes on the chain that are usually codes for one particular amino acid. A type of RNA called tRNA, assembles the protein one amino acid at a time.
What is RNA?
Three Types of RNA.
There are 3 types of RNA. One being mRNA, or messenger, transcribes the genetic code from DNA into a form that can be read and used to make proteins, mRNA carries genetic information from the nucleus, to the cytoplasm of a cell.
Second is rRNA, or ribosomal, is located in the cytoplasm of a cell where ribosomes are found, rRNA directs the translation of mRNA into proteins.
Last is, tRNA, or transfer, like rRNA, it is located in the cellular cytoplasm and is involved in protein synthesis. It transfers amino acids to the ribosome that correspond to each three-nucleotide codon of rRNA.
