(a)

Summary Introduction

To draw: An ‘X’ above enhancers of all the given genes where the activators will bind for the transcription of gene 5.

Concept introduction:

Enhancers are distal control elements located away from the transcribing gene. The control elements of enhancers are short DNA nucleotide sequences. They regulate the expression of specific target genes by binding to the specific transcription factors. These may be either activators (activate transcription) or repressors (repress transcription). Specific activator proteins bind to the control elements of enhancers and promote the transcription.

(b)

Summary Introduction

To draw: A ‘dot’ above the enhancers will bind to green, blue, and orange activators present in a cell and identify which gene would be transcribed.

Concept introduction:

Enhancers are distal control elements located away from the transcribing gene. The control elements of enhancers are short DNA nucleotide sequences. They regulate the expression of specific target genes by binding to the specific transcription factors. These may be either activators (activate transcription) or repressors (repress transcription). Specific activator proteins bind to the control elements of enhancers and promote the transcription.

(c)

Summary Introduction

To identify: The activators that would be present in nerve cells and skin cells to ensure the transcription.

8. Aerobic respiration of a 5 mM solution of tripeptide that is composed of the following three amino acids; alanine, leucine and isoleucine. Alanine breaks down to pyruvate, leucine breaks down to Acetyl-CoA and isoleucine breaks down to succinyl-CoA.

9. Aerobic respiration of one lipid molecule. The lipid is composed of one glycerol molecule connected to two fatty acid tails. One fatty acid is 12 carbons long and the other fatty acid is 18 carbons long in the figure below. Use the information below to determine how much ATP will be produced from the glycerol part of the lipid. Then, in part B, determine how much ATP is produced from the 2 fatty acids of the lipid. Finally put the NADH and ATP yields together from the glycerol and fatty acids (part A and B) to determine your total number of ATP produced per lipid. Assume no other carbon source is available. fatty acids glycerol 18 carbons 12 carbons 0=
