Biology rna polymerase simple definition
Webtranscription factor, molecule that controls the activity of a gene by determining whether the gene’s DNA (deoxyribonucleic acid) is transcribed into RNA (ribonucleic acid). The enzyme RNA polymerase catalyzes … WebTranslation is the final step in the path representing the central dogma of molecular biology: DNA to RNA to protein. Translation involves the ribosome, mRNA, tRNA and amino acids. It is the translation of genetic information from DNA into a triplet codon form, with codons for all 20 amino acids.
