polymerase chain reaction (PCR) do Makes more copies of a sample of DNA

<u>Explanation:</u>

A procedure to create several portraits of a distinct DNA section is termed as Polymerase chain reaction. In other words, it is a lab routine handled to compose various representations of a portion of DNA. PCR is extremely explicit and can be utilized to increase, or model, a particular DNA destination from a hybrid of DNA particles.

In PCR, the effect is regularly cycled within a range of temperature variations, which deduct countless models of the destination range to be exhibited. PCR intends to obtain sufficient of the objective DNA region that it can be examined or applied in some other way.

Chromosomes are composed of deoxyribonucleic acid (DNA) mole

There are mainly two molecules that function as genetic material in living organisms.

These are ribonucleic acid(RNA) and deoxyribonucleic acid(DNA).

The organisms having DNA as genetic material require packaging of DNA as it is a long polymer of deoxyribonucleotides.

In the case of human beings, the length of DNA in a cell is approximately 2.2 meters which is very large as compared to the size of the nucleus( approximately 10^-6 meters).

So, the DNA has to be made compact for it to be present inside the nucleus of a cell.

Therefore, the DNA present inside the nucleus of a cell undergoes coiling and compaction through several stages before finally becoming a chromosome, which is shown in the adjoining diagram.

Thus, chromosomes are composed of deoxyribonucleic acid (DNA) molecules.
