Dna Makes Protein Research Paper

DNA makes proteins. DNA is stored in the nucleus and contains phosphates (a phosphate includes nitrogen bases). DNA is made up of these phosphates, but, in making polypeptides, or a protein, the nitrogen bases are the most important in his process. To make a polypeptide, the helicase unzips the double helix figure, making two rows, or strands, which are one side of all of the nitrogen bases. Floating nitrogen bases string the opposite of these sides, to make an original copy, but leave, ending in one strand of the opposite, original DNA strand. This is called mRNA, and the process of transcription is the process of the mRNA copying the original DNA strand and becoming a second strand. Because DNA is a double helix, it is two wide to fit through the nucleus, but the new mRNA can travel through the nucleus, because it is only one strand. …show more content…
There are two types of endoplasm reticulum(ER), they are rough ER and smooth ER. If a strand of mRNA is lucky enough to go through rough ER (called that because of the ribosomes on the walls of the canal) it can start, and complete the process of translation immediately. If an unlucky strand of mRNA goes through smooth ER, it passes into the cytoplasm. There, tRNA combines with the single strand of mRNA on a free-floating ribosome to form polypeptides (and to complete the process of translation). But how? Amino acids have a trio of tRNA on them. tRNA is just three nitrogenous bases. When mRNA is on the ribosome, it is understood that the nitrogenous bases are set into groups of three. These are called codons. Codons are already pre-determined by a triplet that was formed by the original DNA. This is called a DNA triplet. The amino acid and tRNA, which are already attached to it, are called an anti-codon, because they combine with the
