Trna - Guides d'étude, Notes de cours & Résumés

SimUText: Mendelian Pigs Latest 2023 Graded A+ Explain the general pathway of eukaryotic Membrane protein production in the nucleus of a diploid cell there are 2 alleles. They are both transcribed by RNA polymerase into premRNA. The premRNA is spliced and exits the nucleus where it is associated w/ a tRNA w/ the corresponding anticodon, causing the tRNA (linked to an amino acid) to bind to the ribosome. The mRNA does this by itself binding to the ribosome. The polypedide chain is synthesized. Ri...

Translation - Cellular components are able to read the genetic message in mRNA and translate the message into specific primary amino acid sequence of a protein How does tRNA structure allow for SPECIFICTY in translation? - 1. Plays critical role in ENABLING the translation of the information 2. Each type of tRNA molecule is not identical and can translate a specific codon into a specific amino acid What is the structure of tRNA? - - single RNA strand (70-90 nucleotide length) - four doub...
