The accuracy of the statement, “alternate exons ‘2 and, 3’ in human α-tropomyosin gene have the same number of nucleotides ”. Introduction : During RNA processing, alternate splicing of pre-mRNA produces different mRNA variants from a single gene. This results in synthesis of multiple isoforms of protein encoded by a single gene. In this, certain exons may be included or excluded from the mature mRNA.

Question

In a population of Jackalopes (pictured below), horn length will vary between 0.5 and 2 feet, with the mean length somewhere around 1.05 feet. You pick Jackalopes that have horn lengths around 1.75 feet to breed as this appears to be the optimal length for battling other Jackalopes for food. After a round of breeding, you measure the offsprings' mean horn length is 1.67. What is the heritability of horns length (h2)? Is Jackalope horn length a heritable trait? (4 pts)? 12pt v R Paragraph V BIU A श्र > B

Answer 1

Question

Chapter 6, Problem 8P

A.

Summary Introduction

To determine: The accuracy of the statement, “alternate exons ‘2 and, 3’ in human α-tropomyosin gene have the same number of nucleotides”.

Introduction: During RNA processing, alternate splicing of pre-mRNA produces different mRNA variants from a single gene. This results in synthesis of multiple isoforms of protein encoded by a single gene. In this, certain exons may be included or excluded from the mature mRNA.

B.

Summary Introduction

To determine: The accuracy of the statement, “alternate exons ‘2 and, 3’ in human α-tropomyosin gene must each contain an integral number of codons (that is, the number of nucleotides divided by 3 must be an integer)”.

Introduction: During RNA processing, alternate splicing of pre-mRNA produces different mRNA variants from a single gene. This results in synthesis of multiple isoforms of protein encoded by a single gene. In this, certain exons may be included or excluded from the mature mRNA.

C.

Summary Introduction

To determine: The accuracy of the statement, “alternate exons ‘2 and, 3’ in human α-tropomyosin gene must each contain a number of nucleotides that when divided by 3 leaves the same remainder (that is, 0, 1, or 2)”.

Introduction: During RNA processing, alternate splicing of pre-mRNA produces different mRNA variants from a single gene. This results in synthesis of multiple isoforms of protein encoded by a single gene. In this, certain exons may be included or excluded from the mature mRNA.

There are many differences between DNA replication happening during mitosis in a Douglas fir tree growing in the Oregon Cascade Mountains and DNA replication happening during a PCR reaction in a forestry research lab at Oregon State University where the laboratory is amplifying a Simple Sequence Repeat. Complete the following table that compares the two DNA replication events in terms of the primers, the nucleotides, the polymerase, and the target sequence. Additionally, give a general value for the number of copies of the template DNA after one S phase in one cell and after the lab has completed the PCR reaction.
