Deamination of adenine results in the formation of hypoxanthine. Hypoxanthine selectively base pairs with cytosine. If this error is not corrected, what base pair can the original A·T base pair be converted to after cycles of DNA replication?a) G·C b) C·G c) T·A d) A·G

Please provide explanation for each step

You are studying a colony of cells and determine that some of these cells have a mutated DNA polymerase I that results in loss of function of this enzyme. A)   What will the effect of the mutation in DNA polymerase I be on DNA replication? In your answer make sure to describe what would be observed in the leading and lagging strand and explain your reasoning.  B)   Will this mutation in DNA polymerase I have an impact on another step in DNA replication? In your answer make sure to indicate whether DNA replication will be impacted or not. If it is not, explain why. If it is impacted, then describe the step that is impacted and name the molecule or enzyme involved.

Xeroderma pigmentosum is a genetic disease caused by an error in the nucleotide excision repair process that fixes damage to DNA by ultraviolet light.  Studies have shown that it can result from mutations in any one of seven genes. What can you infer from this finding?   A) There are seven genes that produce the same protein B) These seven genes are the most easily damaged by ultraviolet light. C) There are seven enzymes involved in the nucleotide excision repair process. D) These mutations have resulted from translocation of gene segments.
