英语释义

• an organelle in the cytoplasm of a living cell; ribosomes attach to mRNA and move down it one codon at a time and stop until tRNA brings the required amino acid; when a ribosome reaches a stop codon it falls apart and releases the completed protein mole

  "the ribosome is the site of protein synthesis"

ribosome profilingRibosome profiling (also known as polysome profiling) is a technique that uses messenger RNA (mRNA) to determine what proteins are being translated. It produces a “global snapshot” of all the ribosomes active in a cell at a particular moment.

cytoplasmic ribosome胞质核糖体

active ribosome活性核蛋白体

prokaryotic ribosome原核核蛋白体

bound ribosome固着核糖体

英汉例句
