- A scientist mutates elF-2 to eliminate its GTP hydrolysis capability. How would this mutated form of elF-2 alter translation? Initiation factors would not be able to bind to mRNA The large ribosomal subunit would not be able to interact with itiRNA transcripts tRNAi-Met would not scan mRNA transcripts for the start codon elF-2 would not be able to interact with the small ribosomal subunit.Add-ons Help Last edit was 4 minutes ago Times New.. - BIUA 11 + Using the table the other page- transcribe the RNA sequence int codons and their amino acids: CAU TTG TAU UTA AAA TGG GCG Translation Mechanics Now that you are an expert code breaker, we can start to talk about thanslation. Let's go over the key players in the process. MRNA. The mRNA is the code that is translated into a functional protein. It is created through transcription and a series of subsequent editing steps, which we have described in detail already. The mature mRNA comprises codons that will code for the production of a protein. lili 日Of all of the different codons that exist, three of them ___. do not specifiy a particular amino acid and are signals to terminate translation do not specifiy a particular amino acid and are signals to begin translation are involved in mutations cannot be copied give the signal to stop translation
