During transcription

• protein is synthesized from amino acids.

• DNA is replicated.

• protein is synthesized from DNA.

• RNA is synthesized from DNA.

To express a gene, DNA is first transcribed into a corresponding strand of

• mRNA.

• mtDNA.

• rRNA.

• tRNA.

The DNA template ATGCGTTA is transcribed into an RNA strand with the sequence

• UACGCAAU.

• TACGCAAT.

• AUGCGAAU.

• UAACGCAU.

The nitrogenous base that is in RNA but not in DNA is

• urea.

• uracil.

• thymine.

• thiamine.

A codon consists of three consecutive

• DNA bases.

• tRNA bases.

• mRNA bases.

• amino acids.

The enzyme that synthesizes messenger RNA from a DNA template is

• DNA polymerase.

• reverse transcriptase.

• RNA polymerase.

• ligase.

Parts of an mRNA molecule that are removed before protein synthesis are called

• promoters.

• exons.

• introns.

• exomes.

Ribosomes begin translation of an mRNA transcript at the first

• tRNA.

• AUG.

• anticodon.

• promoter.

Type of bonds form between amino acids during elongation.

• Peptide
