Question

Understand all RNA polymerases' function, what type of RNA is transcribed by what polymerase. (Use genetic code form for this question) One strand of a section of DNA isolated from the bacterium E. coli reads: 5'-GTGCCTACCCATAGG-3'. (a) Suppose that an mRNA is transcribed from this DNA using the complementary strand as a template. What will be the sequence of the mRNA in this region (make user you label the 5' and 3' ends of the mRNA) (b) How many different peptides could potentially be made from this sequence of RNA, assuming that translation initiates upstream of this sequence? (c) What are these peptides?

Explanation / Answer

Ques-1:

Eukaryotes have developed three-polymerase system to control the synthesis of proteins during cell division as an evolutionary aspect.

These three-RNA polymerase system enable eukaryote to promote "profound protein synthesis" to break down macromolecules & to synthesize macromolecules efficiently as eukaryotes are more complex compared to simple single celled prokaryotes & single celled eukaryotes.

RNA polymerase I: This is going to code for large rRNA precursors, 28S, 5.8S, and 18S rRNAs are mainly coded in eukaryotes by RNA polymerase along with mRNA, tRNA

RNA polymerase II: This is going to promote DNA to code for mostly proteins

RNA polymerase III: This is going to promote synthesis of tRNAs including a few snRNAs. This is also going to promote synthesis of 5S ribosomal - RNA along with some small functional RNAs.
