If the deficiency of DAM (deoxyadenosine) methylase will decrease, increase or will have no effect on the mutation rates should be explained. Concept introduction: Deoxyadenosine methylase is commonly referred to as DAM methylase. This is an enzyme that catalyzes the addition of methyl ( CH 3 ) group to the adenine of the sequence of 5 ' − GATC − 3 ' in the DNA (Deoxyribonucleic acid) which is newly synthesized.

Chapter 23, Problem 1P

Interpretation Introduction

Interpretation:

If the deficiency of DAM (deoxyadenosine) methylase will decrease, increase or will have no effect on the mutation rates should be explained.

Concept introduction:

Deoxyadenosine methylase is commonly referred to as DAM methylase. This is an enzyme that catalyzes the addition of methyl ( CH3 ) group to the adenine of the sequence of 5'−GATC−3' in the DNA (Deoxyribonucleic acid) which is newly synthesized.

Expert Solution & Answer

Explanation of Solution

The process of addition of methyl group to the adenine of the sequence of 5'−GATC−3' in the DNA can be referred to as DNA methylation. The process of DNA methylation stabilizes the newly synthesized DNA as well as help in the development of embryo and cell differentiation.

During the process of replication, methylated DNA strand remains temporarily unmethylated. Thus, in the two strands of DNA, one strand of DNA remains methylated, while the other strand of DNA remains unmethylated. This situation is referred to as hem-methylation. The unmethylated strand of DNA quickly methylates in the presence of enzyme dam methylase.

In the deficiency of enzyme dam methylase, DNA is left completely unmethylated. Also, the unmethylated DNA has more probability to undergo mutation. Thus, the deficiency of dam methylase enzyme increases the spontaneous mutation rates.

1. During a feeder study, a small amount of [6-14C]glucose is added to aerobic yeast culture. Where would the 14C label appear in oxaloacetate at the end of one full Krebs cycle? (In this sugar, C6 of glucose is labeled as 14C.) Take this sugar through glycolysis, PDC, and the Krebs cycle until you learn where the label winds up, in oxaloacetate or something else. For full credit, defend your answer by showing me at least the labeled structures of pyruvate, acetyl-CoA, citrate, and all subsequently labeled structures until you get to either labeled oxaloacetate or wherever the labels winds up.
