Document Summary
We"ve cover production of mrna so far. Almost everything in our cells are carried out by proteins. Consist of polypeptide chains (string of amino acids) Amino acids linked together by peptide bonds. Come together in condensation reaction (lose water) One end always has amino group, the other carboxyl. Collinear: the beginning part of gene codes for each in linear fashion: 5" to 3". Translation can start on new message before its done being transcribed. Translation and transcription will keep starting when there"s a new spot. Polypeptide chain longer because it has translated more gene: moving left to right. In eukaryotes, transcription and rna processing occur in the nucleus, and translation occurs in the cytoplasm. We can have multiple translations at once or multiple translations, but they can"t be going on at the same time on the same molecule. Initiation: proteins come in, find mrna and find right part to start translation.
