Webwhy is the language of mRNA often described as a "triplet code"? because every three nucleotide has an amino acid. what are the three stages of translation? initiation, … WebThe transport of mRNA molecules from the nucleus of the cell to the cytoplasm is essential for protein synthesis. The mRNA molecule is moved through the nuclear pores by molecular motors, and once in the cytoplasm, it binds to a ribosome and is ready for translation. tRNA molecules, on the other hand, are not usually transported from the nucleus.

WebWhat is the function of the tRNAs? Transfer ribonucleic acid (tRNA) is a type of RNA molecule that helps decode a messenger RNA (mRNA) sequence into a protein. tRNAs function at specific sites in the ribosome during translation, which is a process that synthesizes a protein from an mRNA molecule.. Where does tRNA #2 move to after this … WebThe correct tRNA with its attached amino acid is selected at each step because each specific tRNA molecule contains a three-base sequence that can base-pair with its complementary code word in the mRNA. 3. … Web10 jul. 2024 · Three processes are required: (1) replication, in which new copies of DNA are made; (2) transcription, in which a segment of DNA is used to produce RNA; and (3) translation, in which the information in RNA is translated into a protein sequence.

"Web10 apr. 2012 · Of course, the length (and thus the mass) of an mRNA varies quite a lot, so it would seem likely that sometimes it's the ribosome that moves mostly, sometimes it's the mRNA, and sometimes it's both. Also, as shigeta and others have pointed out, there can be more than one ribosome attached to the same mRNA strand. " - How many trna molecules can a ribosome hold
