WebLike DNA, RNA is made up of nucleotide consisting of a 5-carbon sugar ribose, a phosphate group, and a nitrogenous base. However, there are three main differences between DNA and RNA: RNA uses the sugar ribose instead of deoxyribose. RNA is generally single-stranded instead of double-stranded. RNA contains uracil in place of thymine. WebApr 28, 2024 · The ribosome contains three important regions – the P (peptidyl) site containing the growing polypeptide, the A (acceptor) site that receives a new charged tRNA and the E (exit) site through which a deacylated tRNA leaves the ribosome.

WebApr 12, 2024 · Ribosomes are downregulated in arrested cells leading to increased cytoplasmic diffusion.
