Chapter 14 - Section 3

Question 1

What techniques are used to study human DNA?

Answer 1

By using tools that cut, separate, and then replicate DNA base by base, scientists can now read the base sequences in DNA from any cell.

Question 2

What were the goals of the Human Genome Project, and what have we learned so far?

Answer 2

The Human Genome Project was a 13-year, international effort with the main goals of sequencing all 3 billion base pairs of human DNA and identifying all human genes.

Question 3

Bioinformatics

Answer 3

application of mathematics and computer science to store, retrieve, and analyze biological data

Question 4

Genomics

Answer 4

study of whole genomes, including genes and there functions

Question 5

What were the goals of the Human Genome Project, and what have we learned so far? 2

Answer 5

The Human Genome Project pinpointed genes and associated particular sequences in those genes with numerous diseases and disorders. It also identified about three million locations where single-base DNA differences occur in humans.

Question 6

Restriction Enzyme

Answer 6

enzyme that cuts DNA at a sequence of nucleotides

Question 7

Gel Electrophoresis

Answer 7

procedure used to separate and analyze DNA fragments by placing a mixture of DNA fragments at the end of a porous gel and applying an electrical voltage to the gel
