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...
