Answer:
Option). It permits hydrogen bonds between DNA strands to dissociate.
Explanation:
PCR (polymerase chain reaction) techniques can bed defined as a technique, which is used for in vitro amplification of sample DNA. It is made up of three steps, denaturation, primer annealing, and extension.
The first step in PCR is heating of sample DNA to denature the double stranded DNA by breaking hydrogen bonding present between bases of double stranded DNA.
Due to this, double strands of DNA get separated and provide templates for synthesis of daughter DNA strands.
Thus, the correct answer is second option.
The area that would be most appropriate for the patient is in the back hallway, in a quiet and private room. This is because if there is a sudden noise, it can cause or trigger a seizure in a patient with severe preeclampsia. Therefore, the best room replacement should be far form the elevator, nurse's station and the nursery.
It needs to be copied into rna to make a new copy for cells to divide
When we divide the surface area by the volume, we get the surface area to volume ratio:
surface to volume ratio = surface area/volume = 32/8 = 4This ratio indicates how much exposure the cell has to the environment which is important in cells in regard to the transport, absorption, or secretion of materials.
