q # 5 please
For the molecules below, in which case DNA polymerase will be able to start the eiation? RNA polymerase to start the transcription? Briefly explain. A. 3 GAATCTGC.5 S CTTAGACG-3 C. 1 3'-GAATCTGC-S 2 or5 GAATCTGCAA-3' 3'AGACGIT-5 5-CTT-3 D. 13'-GAATCTGC-s 2 5 GAATCTGCAA-3 3'AGACGUU-5 -CUU-3 ONA pol 2 RNA 6. The diagram below shows a structure of an cukaryotic different part of a gene. Using the pattern, label the diagram for the location of the following a. enhancer, b- promoter, c- transcription start, d- translation start; e- exon, i- intron, r. coding sequence, tl transcription stop, t2-translation stop gene. Each pattera refers to a a 45 pts Put the corresponding letter on top of the pattern to show the location b. (2 pt) How pre-mRNA trainseribed from this gene will look like? Just use letters (as above) c mature mRNA?(2 pts)Explanation / Answer
DNA polymerase can start the replication in cases:
C1 and D1.
DNA polymerases require a primer (a short strand of RNA or DNA, generally about 18-22 bases) with a free 3?-hydroxyl group, already base-paired to the template, to initiate the replication. They cannot start from scratch by adding nucleotides to a free single-stranded DNA template.
RNA polymerase can start the transcription in case
B.
RNA polymerase does not require primer to initiate transcription. It binds promoter region of a double stranded DNA and initiate transcription by taking one strand of DNA (3'->5') as template and synthesize an RNA strand complementary to it (similar to other strand of DNA, coding strand 5'->3').
