5 Multiple choice questions
- An enzyme that links together the growing chain of ribonucleotides during transcription.
- The synthesis of RNA on a DNA template.
- The premise that a gene is a segment of DNA that codes for one polypeptide.
- A mutation involving the addition of one or more nucleotide pairs to a gene.
- Modification of RNA before it leaves the nucleus, a process unique to eukaryotes.
5 True/False questions
transcription unit → The synthesis of RNA on a DNA template.
E site → One of a ribosome's three binding sites for tRNA during translation. Holds the tRNA carrying the next amino acid to be added to the polypeptide chain.
primary transcript → An initial RNA transcript; also called pre-mRNA when transcribed from a protein-coding gene
missense mutation → The most common type of mutation, a base-pair substitution in which the new codon makes sense in that it still codes for an amino acid.
transfer RNA (tRNA) → An RNA molecule that functions as an interpreter between nucleic acid and protein language by picking up specific amino acids and recognizing the appropriate codons in the mRNA.
