Answer:
A or B
Explanation:
To be honest both are accurate.
The DNA is condensed before replication in the form of chromosomes and then the chromosomes are divided.
The higher the GC content of a DNA, the higher the strength of the interchain interactions, and the higher the melting temperature.
DNA is Deoxyribonucleic Acid. It is the genetic material in maximum of the organisms. The DNA is a polymer made from nucleotides (sugar, nitrogenous bases and phosphate group). It is composed of two strands of phosphate and sugar backbone in an antiparallel direction. The nitrogenous bases present in DNA are Adenine (A), Thymine (T), Guanine (G) and Cytosine (C).
GC content refers to the total amount of Guanine and Cytosine present in the DNA. Since there exists a triple bond between G and C, more percentage of them provides strength to DNA. That is why high GC content denotes high melting temperature of DNA.

The correct answer for this question would be the second option. The one who invented he polymerase chain reaction (PCR) that allowed scientists to enlarge and study genetic material is Kary Mullis. PCR is <span> a technique that amplifies specific DNA sequences from very small amounts of </span>genetic material<span>. Mullis invented this while he is at Cetus. </span>
