Chapter 18, Problem 27P

Summary Introduction

a.

To determine:

The important sequences that are required to regulate the hunchback gene expression that is found in the transcriptional regulatory region of the hunchback.

Introduction:

The genes are the sequence of nucleotides that are present on the chromosomes and encode for a specific protein that plays a crucial role in the functioning of the different processes in an organism. The gene is located at specific gene loci and can be structural or regulatory in nature.

Summary Introduction

b.

To determine:

The sequence elements that code for specific protein domains that are found in the structural region of hunchback.

Introduction:

The genotype is the genetic constitution of the organism, while the phenotype refers to the external characters visible in an organism. The alleles are the contrasting forms of a gene, and one of them is dominant, and the other is recessive.

Summary Introduction

c.

To determine:

The significant sequence that is present in the 3’ UTR of the hunchback mRNA and the importance of the sequence.

Introduction:

The two stages of protein synthesis are transcription and translation. The transcription is the process where the DNA is converted into the mRNA by the action of DNA polymerase. A single strand of the DNA works as a template and leads to the formation of an mRNA molecule that is formed inside the nucleus. This mRNA is then transported into the cytoplasm where it is converted into protein chains through the action of tRNA and ribosomes.

When the amino acid levels in eukaryotic cells are low, general protein synthesis is reduced. Gcn4 translation, however, is increased. A. What would happen under high and low amino acid conditions if only one of the upstream ORFs were deleted from Gcn4? B. What would happen under high and low amino acid conditions if all of the upstream ORFs were deleted from Gcn4?

A human gene was initially identified as having three exons and two introns. The exons are 456, 224, and 524 bp,whereas the introns are 2.3 kb and 4.6 kb.a. Draw this gene, showing the promoter, introns, exons,and transcription start and stop sites.b. Surprisingly, this gene is found to encode not onebut two mRNAs that have only 224 nucleotides incommon. The original mRNA is 1204 nucleotides, andthe new mRNA is 2524 nucleotides. Use your drawing

a. How do bacteria increase the efficiency of gene expression? Is this possible in eukaryotes? b. A mutation in the promoter of Gene K disrupts an enzyme binding site and results in the loss of Gene K expression. Is this change in gene expression likely happening at the transcriptional or the translational level? Explain. c. Propose three different mutations to prevent initiation, elongation, and termination of bacterial transcription, respectively. Explain how/why each mutation would prevent its respective step. (Hint: mutations can be in genes that encode proteins or regulatory DNA sequences)
