- template strand
- nonsense mutation
- E site
- a 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.
- b 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.
- c The DNA strand that provides the template for ordering the sequence of nucleotides in an RNA transcript.
- d A mutation that changes an amino acid codon to one of the three stop codons, resulting in a shorter and usually nonfunctional protein
- e One of a ribosome's three binding sites for tRNA during translation. The place where discharged tRNAs leave the ribosome.
5 Multiple choice questions
- A coding region of a eukaryotic gene or expressed region
- 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.
- A mutation involving the addition of one or more nucleotide pairs to a gene.
- The premise that a gene is a segment of DNA that codes for one polypeptide.
- within ex: intron
5 True/False questions
TATA box → A rare change in the DNA of a gene, ultimately creating genetic diversity.
promoter → A specific nucleotide sequence in DNA that binds RNA polymerase and indicates where to start transcribing RNA
ribozyme → An enzymatic RNA molecule that catalyzes reactions during RNA splicing.
RNA processing → Modification of RNA before it leaves the nucleus, a process unique to eukaryotes.
trans- → opposite ex: anticodon
