errors in dna replication can contribute to the development of: a. enhanced dna repair b. improved genetic integrity c. genetic disorders and diseases d. healthy cellular functions
what is the role of dna polymerase in dna replication? a. to unwind the dna double helix b. to seal gaps between dna fragments c. to initiate the replication process d. to add nucleotides to the growing dna strand
how are okazaki fragments formed during dna replication? a. by unwinding the dna double helix b. by continuous synthesis of the leading strand c. by synthesizing short segments on the lagging strand d. by the action of ligase sealing gaps
what initiates dna replication by unwinding the double helix? a. okazaki fragments b. helicase

Explanation:

1. DNA replication is the process that copies DNA before cell - division, ensuring each daughter cell gets an identical set of chromosomes.
2. Genetic integrity in DNA replication is crucial for accurate transmission of genetic information from one generation of cells to the next.
3. A mutation is an error that occurs during DNA replication, which can change the DNA sequence.
4. Errors in DNA replication can lead to genetic disorders and diseases as they alter the normal genetic code.
5. DNA polymerase adds nucleotides to the growing DNA strand during replication.
6. Okazaki fragments are formed by synthesizing short segments on the lagging strand during DNA replication.
7. Helicase initiates DNA replication by unwinding the double - helix structure of DNA.

Answer:

1. a. DNA replication
2. a. It ensures accurate transmission of genetic information
3. d. An error that occurs during DNA replication
4. c. Genetic disorders and diseases
5. d. To add nucleotides to the growing DNA strand
6. c. By synthesizing short segments on the lagging strand
7. b. Helicase
