a.double-stranded DNA,
b.four kinds of dNTPs, primers, origins of replication ligase, primers, nucleases topoisomerases, telomerases, polymerases nucleosome loosening,
c.four dNTPs, four rNTPs G-C rich regions, polymerases, chromosome nicks

Answer 1

The set of materials required for replication in both eukaryotes and prokaryotes includes double-stranded DNA, four kinds of dNTPs, primers, origins of replication, and ligase.

Step-by-step explanation:

The set of materials required for replication in both eukaryotes and prokaryotes includes:

1. Double-stranded DNA: the genetic material that serves as a template for replication.
2. Four kinds of dNTPs: deoxyribonucleotide triphosphates, which are used as building blocks to synthesize new DNA strands during replication.
3. Primers: short RNA or DNA sequences that provide a starting point for DNA polymerase during replication.
4. Origins of replication: specific sites on the DNA molecule where replication begins.
5. Ligase: an enzyme that seals the gaps between newly synthesized DNA fragments, called Okazaki fragments, on the lagging strand during replication.

Answer 2

Double-stranded DNA.

Step-by-step explanation:

Replication may be defined as the process of formation of the daughter DNA from the parent DNA with the help of enzymes and proteins. The three main process of replication are inititation , elongation and termination.

The double stranded DNA molecule undergoes the process of replication. Four different dNTPs - adenine, guanine, thymine and cytosine are required for the process of replication. Primers are required for initiation of the process of replication and ori region is the inititaion point of replication.

Thus, the correct answer is option (a).
