12+ Biology Replication Transcription Translation Pictures. Genes provide information for building proteins. Evolution (dna replication is not perfect).
This is a fascinating subject that is certain to advance rapidly over the next few years. Transcription is the first of several steps of dna based gene expression in which a particular segment of dna is copied into rna (especially mrna) by the enzyme rna polymerase. A) different enzyme for synthesis of lagging and leading strand.
The portion of the dna that codes for genes is transcribed, or copied, into messenger rna, known as mrna.
The synthesis of rna is called transcription because it is simply the copying of dna language into rna. Evolution (dna replication is not perfect). Dna, mrna, trna, rrna, and amino acids. Genes provide information for building proteins.
