ANTHRO 101 Lecture Notes - Lecture 6: East Los Angeles College, Polymer, Transfer Rna
Document Summary
Transcription: is the first step of gene expression, in which a particular segment of dna is copied into rna (mrna) by the enzyme rna polymerase. Both dna and rna are nucleic acids, which use base pairs of nucleotides as a complementary language. Translation: translation is the process in which cellular ribosomes create proteins. In translation, messenger rna (mrna) produced by transcription from dna is decoded by a ribosome to produce a specific amino acid chain, or polypeptide. Mrna: is a large family of rna molecules that convey genetic information from. Ribosomes: a minute particle consisting of rna and associated proteins, found in large numbers in the cytoplasm of living cells. Amino acids: a simple organic compound containing both a carboxyl ( . Codon: is a sequence of three dna or rna nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis.
