Question

The sequences at the ends of linear chromosomes are called _______________. A protein that uses ATP hydrolysis to separate the two DNA strands during replication is called _______________. The small segments of DNA synthesized on the lagging strand during replication are called _______________ fragments. Addition of deoxyribonucleotides to DNA is catalyzed by ________________. DNA must be relaxed during replication by _______________. A. Single-stranded binding protein B. helicase C. model D. telomeres E. polymerase F. Holliday G. topoisomerase H. Okazaki

Answer 1

Answer: Telomeres, Helicases, Okazaki, DNA polymerase, Topoisomerase

Explanation:

1. Telomeres these are set of repetitive nucleotide sequence found at the end of a linear chromosomes they help preventing the DNA chromosome frrom sticking to other DNA chromosomes.

2. Helicases are proteins that uses energy (ATP) to unwind DNA strands during replication.

3. Okazaki fragments the small DNA nucleotide sequence synthesized separately on the lagging strand.

4. DNA polymerase are enzymes that catalyzes the addition of deoxyribonucleotides to DNA during replication.

5. Topoisomerase are enzymes that prevent single stranded DNA from supercoil, rumple and winding back during replication.
