How are the DNA polymerases used in nature (DNA replication) and sequencing different?

What other steps in DNA sequencing are different than prokaryotic DNA replication?

Solutions

Expert Solution

(a)DNA polymerase replication:

-DNApolymerase are enzymes that synthesize DNA molecules from deoxyribonucleotides, the building blocks of DNA. These enzymes are essential for DNA replication and usually work in pairs to create two identical DNA strands from a single original DNA molecule. During this process, DNA polymerase "reads" the existing DNA strands to create two new strands that match the existing ones.

DNA polymerase adds nucleotides to the 3'- end of a DNA strand, one nucleotide at a time.

DNA sequencing:-is the process of determining the precise order of nucleotideswithin a DNA molecule. It includes any method or technology that is used to determine the order of the four bases—adenine, guanine, cytosine, and thymine—in a strand of DNA.

structure of DNA has four bases: thymine (T), adenine (A), cytosine (C), and guanine (G). DNA sequencing is the determination of the physical order of these bases in a molecule of DNA.

The DNA polymerases used over many years for Sanger dideoxynucleotide termination sequencing of DNA have had one common feature: they all were intentionally chosen to lack 3’à 5’ exonuclease activity, the proofreading function that many DNA polymerases carry to maintain high fidelity. Why would having proofreading exonuclease activity within the polymerase be detrimental to the Sanger sequencing technique? If you were to substitute a polymerase with proofreading capability, how might that affect the distribution of the bands of DNA produced...

You are curious how the three eukaryotic DNA polymerases assemble at the replication origin. To study this, your lab has purified DNA polymerases, a DNA template with a replication origin, and a procedure for measuring DNA-bound polymerases. You carry out experiments to see the effect of leaving out a DNA polymerase and obtain the results in the table. POLYMERASES INCLUDED DNA-BOUND POLYMERASE α, ε ε α, δ δ δ, ε δ, ε α, δ, ε α, δ, ε 4.
