Question 3

Why are the complementary base-pairing rules so important when a cell needs to copy its DNA?

Accepted Answer

A)  The cells need both strands to be accurate because each strand codes for one half of the gene. 
B)  As long as there is one strand, a copy can be made by following the pairing rules. 
C)  Unless the bases pair up correctly, the DNA strand can break apart. 
D)  Transcription cannot proceed unless the pairs are in the proper sequence.

Question 4

A goal of genomics is to ________.

Accepted Answer

A)  understand the mechanisms that control gene expression 
B)  provide a way to produce large quantities of a particular gene product 
C)  manipulate genetic material for human purposes 
D)  regulate how genes are expressed without changing the protein they encode

Question 5

Scientists study the genomes of many different living organisms besides humans, including, for example, fruit flies, yeasts, and mice. Of what value is understanding the genes of a mouse in comparison to those of a human? Are the two even remotely comparable?

Accepted Answer

The answer of Scientists study the genomes of many different...

Question 6

UV rays from the sun cause a specific type of improper base pairing called a thymine dimer. If a cell cannot correct this problem, the section of DNA can be removed, causing a deletion of several nucleotides. What will this cause?

Accepted Answer

A)  A point mutation forms that leads to a change in one amino acid. 
B)  A point mutation forms that leads to changes in a handful of amino acids. 
C)  The codons shift by one letter, and all the codons before the mutation are changed. 
D)  The codons could shift by one letter, and all the codons after that point would be off.

Question 7

Changes in the DNA are called ________.

Accepted Answer

The answer of Changes in the DNA are called ________....

Question 8
