Chapter 20, Problem 20.6PS

(a)

Summary Introduction

To determine: Whether the statement, “An enhancer may increase the frequency of transcription initiation for its associated gene when it is located 1000 nucleotides upstream of the gene’s core promoter.” is true or false.

Introduction: A short part of the DNA which is involved in increasing the probability of transcription of a particular gene is called an enhancer. It is usually 50-1500 base pairs long. Usually, proteins such as activators bind it to the DNA.

(b)

Summary Introduction

To determine: Whether the statement, “An enhancer may increase the frequency of transcription initiation for its associated gene when it is in the gene’s coding region.” is true or false.

Introduction: A short part of the DNA which is involved in increasing the probability of transcription of a particular gene is called an enhancer. It is usually 50-1500 base pairs long. Usually, proteins such as activators bind it to the DNA.

(c)

Summary Introduction

To determine: Whether the statement, “An enhancer may increase the frequency of transcription initiation for its associated gene when no promoter is present” is true or false.

Introduction: A short part of the DNA which is involved in increasing the probability of transcription of a particular gene is called an enhancer. It is usually 50-1500 base pairs long. Usually, proteins such as activators bind it to the DNA.

(d)

Summary Introduction

To determine: Whether the statement, “An enhancer may increase the frequency of transcription initiation for its associated gene when it causes looping out of the intervening DNA.” is true or false.

Introduction: A short part of the DNA which is involved in increasing the probability of transcription of a particular gene is called an enhancer. It is usually 50-1500 base pairs long. Usually, proteins such as activators bind it to the DNA.

(e)

Summary Introduction

To determine: Whether the statement, “An enhancer may increase the frequency of transcription initiation for its associated gene when it causes alternative splicing of the DNA.” is true or false.

Introduction: A short part of the DNA which is involved in increasing the probability of transcription of a particular gene is called an enhancer. It is usually 50-1500 base pairs long. Usually, proteins such as activators bind it to the DNA.
