The double helix will be split by DNA helicase and transcribed by Pol III HE to make an exact replica of each strand. Pol III HE will synthesize the new phosphodiester-bonded deoxyribose backbone with the help of primase to act as an RNA primer and supply the 3 ' piece for Pol III HE to use to synthesize the DNA in the 5 ' to 3 ...

The process could not begin at the blue triangle because helicase is needed to separate the strands of DNA and initiate the process. TGF-B1 is a protein that affects cell growth and differentiation. Scientists conducted an experiment where epithelial cells were treated with transforming growth factor beta 1 (TGF-B1) in the laboratory.

To sketch the helicase on the provided diagram using a small square, locate the replication fork where the DNA strands separate. Indicate the position of the helicase at this point by drawing a small square and then draw arrows to show the directionality of the newly fragmented lagging strand from 5' to 3'.

What factors control the height of the activation barrier for helicases? What is one main difference between an active helicase and a passive helicase? What is the consequence of employing an active helicase, relative to transcription or replication, when considering rate of unwinding and translocation along the

Question: Which arrow(s) point(s) to the location of helicase in the following image? 0.26cm OC A and E Band D Show transcribed image text There are 4 steps to solve this one.

Question: Which of the following describes a function of DNA helicase?Multiple Choicere-creates the broken hydrogen bonds so that DNA becomes double-stranded againadds nucleotides to the growing 3' end of the new DNA strandconnects the Okazaki fragments and seals any breaks in the sugar-phosphate backbonecreates the lagging strand in semiconservative

One allele, called rs, confers resistance to RS2014, an antibiotic that works by inhibiting helicase activity. Bacteria with the rss allele are sensitive to RS2014. Another allele, called ts produces a temperature sensitive mutation of the helicase. In bacteria with the ts allele, helicase is inactivated at 42 °C but functions normally at 37 °C.

Question: Rho helicase terminates transcription by: a. melting the RNA-DNA duplex, which causes RNA polymerase to fall off. b. catalyzing the formation of RNA hairpins that displace RNA polymerase. c. melting the DNA helix, which prevents RNA polymerase from advancing. d. melting the DNA helix to reveal a transcription termination sequence.
