Chapter 13, Problem 1SA

A heterozygous individual has _______ for a trait being studied.

a. the same allele on both homologous chromosomes

b. two different alleles of a gene

c. a haploid condition, in genetic terms

Expert Solution & Answer

Summary Introduction

Introduction:

Individuals in the population carry a specific set of alleles, known as genotype. The examples of genotype are homozygous and heterozygous. The phenotype of a plant depends on its genotype, and it is the trait of the individual that can be observed.

Answer to Problem 1SA

Correct answer:

Two different alleles of a gene are carried by a heterozygous individual for a trait being studied. Hence, the correct answer is option b.

Explanation of Solution

Reason for correct answer:

Option b. is given as “two different alleles of a gene.”

Locus represents the “location of a gene” on a chromosome. Individuals carry two copies of a gene because their cells are diploid and pairs of the chromosome are present in these cells. These double copies of any gene can be similar, or they can vary as alleles. If an individual carries two different alleles at a particular locus then its genotype would be called heterozygous.

Reason for incorrect answer:

Option a. is given as, “the same allele on both homologous chromosomes.”

If an individual has the same allele on both homologous chromosomes then the individual would be known as homozygous. Hence, option a. is incorrect.

Option c. is given as, “a haploid condition, in genetic terms.”

In individuals there are always two copies of genes are present. So, a heterozygous individual is a diploid condition, not a haploid condition. Hence, option c. is incorrect.

Hence, the options a. and c. are incorrect.

Conclusion

Therefore, the alleles of a gene on both homologous chromosomes would be different in a heterozygous individual. Thus, the correct option is b.

Molecular Biology Please help with question. thank you You are studying the expression of the lac operon. You have isolated mutants as described below. In the presence of glucose, explain/describe what would happen, for each mutant, to the expression of the lac operon when you add lactose AND what would happen when the bacteria has used up all of the lactose (if the mutant is able to use lactose).5. Mutations in the lac operator that strengthen the binding of the lac repressor 200 fold 6. Mutations in the promoter that prevent binding of RNA polymerase 7. Mutations in CRP/CAP protein that prevent binding of cAMP8. Mutations in sigma factor that prevent binding of sigma to core RNA polymerase

Molecular Biology Please help and there is an attached image. Thank you. A bacteria has a gene whose protein/enzyme product is involved with the synthesis of a lipid necessary for the synthesis of the cell membrane. Expression of this gene requires the binding of a protein (called ACT) to a control sequence (called INC) next to the promoter. A. Is the expression/regulation of this gene an example of induction or repression?Please explain:B. Is this expression/regulation an example of positive or negative control?C. When the lipid is supplied in the media, the expression of the enzyme is turned off.Describe one likely mechanism for how this “turn off” is accomplished.
