Codon A sequence of three nucleotides that codes for a specific amino acid during protein synthesis. The genetic code uses 64... Polymerase An enzyme that synthesizes long chains of nucleic acids (DNA or RNA) by reading a template strand. DNA polymerase copies... Promoter (Genetics) A DNA sequence where RNA polymerase binds to begin transcription. Promoters control when, where, and how strongly genes... Replication The process by which DNA makes a copy of itself before cell division. Each strand serves as a template for a new complem... Telomere Repetitive DNA sequences at chromosome ends that protect genetic information. Telomeres shorten with each cell division,... Transcription The process of copying a gene's DNA sequence into messenger RNA. RNA polymerase reads the DNA template and synthesizes a... Translation (Biology) The process by which ribosomes decode messenger RNA to build proteins. Each three-nucleotide codon specifies one amino a...
