Question

errors in dna replication can contribute to the development of:
a. healthy cellular functions
b. genetic disorders and diseases
c. improved genetic integrity
d. enhanced dna repair
what is the significance of genetic integrity during dna replication?
a. it enhances genetic diversity
b. it prevents mutations
c. it ensures accurate transmission of genetic information
d. it allows for faster cell division
what happens during the termination phase of dna replication?
a. nucleotides are added to the growing strand
b. specific sequences signal the completion of replication
c. dna strands are unwound
d. new dna strands are synthesized

Explanation:

First Question:

Errors in DNA replication mean incorrect copying of genetic material. Healthy functions (a) are not caused by errors. Improved integrity (c) and enhanced repair (d) are opposite to what errors cause. Errors can lead to mutations, which cause genetic disorders/diseases (b).

Genetic integrity in DNA replication is about preserving accurate genetic info. Enhancing diversity (a) is via mutations, not integrity. Preventing mutations (b) is part of it but the main significance is accurate transmission (c). Faster cell division (d) is not related to integrity.

Termination phase of DNA replication is when replication stops. Adding nucleotides (a) is elongation. Unwinding strands (c) is initiation. Synthesizing new strands (d) is elongation. Specific sequences signal completion (b) in termination.

Answer:

b. Genetic disorders and diseases
