WebApr 9, 2024 · Figure 15.3. 2: Eukaryotic mRNA contains introns that must be spliced out. A 5' cap and 3' poly-A tail are also added. A scientist splices a eukaryotic promoter in front of a bacterial gene and inserts the gene in a bacterial chromosome. Would you expect the bacteria to transcribe the gene? WebOnce transcribed, eukaryotic mRNA typically undergoes substantial alteration that includes - linkage to histone molecules - fusion into circular forms known as plasmids - union with ribosomes - excision of introns excision of introns The primary structure of a protein is determined by - pleated sheets.

WebDec 8, 2014 · This paper is a review of currently available data concerning interactions of tRNAs with the eukaryotic ribosome at various stages of translation. These data include the results obtained by means of cryo-electron microscopy and X-ray crystallography applied to various model ribosomal complexes, site-directed cross-linking with the use of tRNA … WebOnce the mRNA is produced, it must be processed before it can be translated into a protein. This processing includes the addition of a cap and a poly-A tail to the mRNA strand. The cap and poly-A tail protect the mRNA from degradation and also help the mRNA bind to the ribosome, the organelle responsible for protein translation. spar victor hugo
