- E site
- primary transcript
- a 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.
- b An initial RNA transcript; also called pre-mRNA when transcribed from a protein-coding gene
- c write ex: transcription
- d One of a ribosome's three binding sites for tRNA during translation. The place where discharged tRNAs leave the ribosome.
- e A complex assembly that interacts with the ends of an RNA intron in splicing RNA, releasing the intron and joining the two adjacent exons.
5 Multiple choice questions
- An enzymatic RNA molecule that catalyzes reactions during RNA splicing.
- Modification of RNA before it leaves the nucleus, a process unique to eukaryotes.
- 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.
- The synthesis of RNA on a DNA template.
- 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.
5 True/False questions
anti- → within ex: intron
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.
trans- → across ex:transcription
mutagen → A rare change in the DNA of a gene, ultimately creating genetic diversity.
