- One of a ribosome's three binding sites for tRNA during translation. The place where discharged tRNAs leave the ribosome.
- The synthesis of a polypeptide using the genetic information encoded in an mRNA molecule. There is a change of languagefrom nucleotides to amino acids
- 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 True/False questions
P 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.
TATA box → A rare change in the DNA of a gene, ultimately creating genetic diversity.
ribosome → 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.
base-pair substitution → A mutation occurring when the number of nucleotides inserted or deleted is not a multiple of three, resulting in the improper grouping of the following nucleotides into codons.
transcription → The synthesis of RNA on a DNA template.
