ANTH 101 Lecture Notes - Lecture 4: Allosome, Guanine, Zygosity
Document Summary
Rungs - base pairs are nitrogen based molecules. Dna unzips and two new strands are formed. Helps carry out the instructions contained in dna. Messenger rna (mrna) makes copies of select portions of dna called gene. Mrna copies a portion of dna (a gene) Goes inside nucleus of cell, opens up dna, and takes a snapshot. Once outside the nucleus, a ribosome can attach to the mrna. Ribosome is a structure composed of primarily rna. Use transfer rna to read the mrna three base pairs at a time. Amino acids build up and are held together by peptide bonds. A series of amino acids builds on the end of the ribosome until a stop codon in read. These series of amino acids form a polypeptide chain. Dna results in the formation of you. Genotype is the genetic code responsible for phenotype. The portion of dna read by rna resulting in the formation of different proteins.
