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
trans- → across ex:transcription
point mutation → 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.
mutation → A chemical or physical agent that interacts with DNA and causes a mutation.
