- point mutation
- a opposite ex: anticodon
- b A change in a gene at a single nucleotide pair
- c A mutation involving the addition of one or more nucleotide pairs to a gene.
- d A specific nucleotide sequence in DNA that binds RNA polymerase and indicates where to start transcribing RNA
- e An enzymatic RNA molecule that catalyzes reactions during RNA splicing.
5 Multiple choice questions
- In prokaryotes, a special sequence of nucleotides in DNA that marks the end of a gene. It signals RNA polymerase to release the newly made RNA molecule, which then departs from the gene.
- out, outside, without
- A cell organelle constructed in the nucleolus and functioning as the site of protein synthesis in the cytoplasm; consists of rRNA and protein molecules, which make up two subunits.
- 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.
- A noncoding, intervening sequence within a eukaryotic gene.
5 True/False questions
P site → One of a ribosome's three binding sites for tRNA during translation. Holds the tRNA carrying the growing polypeptide chain. (P stands for peptidyl tRNA
RNA splicing → The removal of noncoding portions (introns) of the RNA molecule after initial synthesis.
intro- → A noncoding, intervening sequence within a eukaryotic gene.
deletion → 1) A deficiency in a chromosome resulting from the loss of a fragment through breakage. (2) A mutational loss of one or more nucleotide pairs from a gene.
poly- → opposite ex: anticodon
