Question

1) What is the ultimate goal of the Human Genome Project?

A) to rid the human population of genetic disease

B) to better understand the genes and regulatory elements of the genome

C) to map all the genes in the genome so they can be edited with CRISPR-cas

D) to understand all of the proteins generated in a cell

2) ________ alleles are those that are not epistatic over nonallelic genes that influence the same phenotypic characteristic.

A) Additive

B) Nonadditive

C) Threshold

D) Discontinuous

3) A PCR was designed to clone a DNA sequence of 1.5 kb. When the products were run on an agarose gel, there was a smear of bands ranging from 1.5 kb to 6 kb. Which of the following is a reason for this result?

A) the polymerase overran the reverse primer

B) the polymerase denatured

C) one of the primers did not bind

D) the thermocycler malfunctioned

Answer 1

1. Option B.

The aim of human genome project was that to provide complete sequence of the human genome.

2. Option A. Additive alleles.

Additive allele determine the phenotype based on the presence or absence of that allele. Phenotype resulting from additive allele depends on the number of alleles present.

3. C. One of the primers did not bind.
