Compare and contrast the properties of DNA polymerase and RNA polymerase.

Drag the appropriate items to their respective bins.

Expert Solution

Only RNA	only DNA	both
Use ribonucleotide triphosphates as substrate	use deoxyribonucleotide triphosphates as substrate	dependent on a DNA sequence template
Can initiate strand synthesis	can only extend an existing strand	polymerize in a 5'-3' direction
	Can proofread using a 3'-5' exonuclease activity	catalyze the phosphodiester bond formation.

DNA and RNA Compare and contrast DNA and RNA. Discuss why humans did not evolve with one central repository of DNA, but rather it is replicated throughout the body? Your assignment should be 250-500 words in length. IN YOUR OWN WORDS PLEASE!!!! NO PLAGIARISM!!!!!!

9.) During the process of DNA replication, both DNA polymerase and RNA polymerase are involved in eventually creating the new daughter strand of DNA. T or F 10.) Replication begins at the origin of replication or ORI and transcription begins at the first codon for methionine. T or F 11.) The process of mapping, sequencing and analysis of proteins is called genomics. T or F 12.) The heavy chain constant domains of a given immunoglobulin molecule define its class. T...

The enzyme required for transcription is * RNA polymerase Restriction enzymes Splicesome DNA polymerase

Compare and contrast the difference between DNA and RNA synthesis in human cells.

You do a series of incubations to compare the properties of E. coli DNA polymerase I and III. After incubating DNA template prepared from bacteriophage T7 with one or the other polymerase for 20 min, you add an excess of a second template, phage T3 DNA and continue the reaction for a further 40 min. You compare the amounts of T3 synthesized to the amount of T7. Most of the DNA synthesized in the polymerase I incubations is found to...

A promoter is ______. a. a sequence in DNA that brings RNA polymerase near the site for transcription b. one or more eukaryotic proteins that bind to DNA near the start of a gene c. a protein that associates with bacterial RNA polymerase to help it bind to DNA d. a sequence in RNA that promotes the release of RNA polymerase from DNA Which of the following statements best describes the promoter of a protein-coding gene? a. A site where...
