Question

Which of the following statements is TRUE? Since RNA polymerase II can locate promoter sequences, most of eukaryotic gene regulation involves repressor action. Mediator is a sequence-specific DNA binding protein that binds to response elements in enhancers and promoter proximal sites. The universal genetic code is read 5 rightarrow 3'. and a protein is synthesized from the amino- to the carboxyl-terminus. Eukaryotic elongation factors (eEFs) bind to the 40S ribosomal subunit prior to formation of the translation initiation complex. Phosphorylation of tyrosine in a protein does not alter the isoelectric point of a protein. Which of the following steps in preparation of a eukaryotic mRNA occurs in a transcription factory in a eukaryotic cell? Transcription Capping Splicing Polyadenylation All of the above

Explanation / Answer

ANSWER:

43)TRUE, The universal genetic code 5'-3'.and a protein is synthesized from the amino to the carboxyl terminus.

44) SPLICING

In splicing, some sections of the RNA transcript (introns) are removed, and the remaining sections (exons) are stuck back together.
