Proteins required for nuclear import Ran : a monomeric G protein that exists in two conformations, one when bound to GTP and a different one when bound to GDP. Importin α and β : a heterodimeric nuclear- import receptor. Importin α binds to NLS, importin β binds to FG-nucleoporins.

The genetic code The genetic code is comma-less (no interruptions between codons), overlapping (it can be read in three possible frames), and degenerate (more than one codon can encode the same amino acid). The AUG codon for methionine is the usual start codon. Three codons (UAA, UAG, and UGA) function as stop codons.

are involved in protein synthesis Messenger RNA: carries the genetic information from DNA in the form of codons. Transfer RNA: deciphers the codons in mRNA. Each type of amino acid has one or more tRNAs which bind it and which can carry it into a growing polypeptide chain. tRNA has a three-nucleotide anticodon that
