Web1. small subunit attaches to the mRNA with methylated cap and moves to the initiation site 2. tRNA anticodon binds to the start codon and the large ribosomal subunit binds so that the tRNA is in the P site 3. The next tRNA attaches to the next codon in the A site 4. The amino acid from the first codon is transferred to the second by peptidyl transferase and the first … The ribosome has three binding sites for tRNA molecules that span the space between the two ribosomal subunits: the A (aminoacyl), P (peptidyl), and E (exit) sites. In addition, the ribosome has two other sites for tRNA binding that are used during mRNA decoding or during the initiation of protein synthesis. These are the T site (named elongation factor Tu) and I site (initiation). By convention, the tRNA binding sites are denoted with the site on the small ribosomal subunit liste…

DNA vs. RNA – 5 Key Differences and Comparison

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. Web17 mrt. 2024 · Transfer RNA, or tRNA, is a specialized RNA molecule that brings amino acids to the ribosome for protein production. In eukaryotic cells, tRNA is made by a special protein that reads the DNA sequence and makes an RNA copy, or pre-tRNA. Pre-tRNA is processed once it leaves the nucleus. How does mRNA become tRNA?
