Genome

Question 1

What is a genome?

Answer 1

A complete set of genetic instructions

Question 2

How is the genome packaged?

Answer 2

Chromosomes

Coiled linear strands of DNA

Question 3

What are the two categories of DNA in the genome?

Answer 3

Unique and Repetitive

Question 4

How often is unique DNA present in the genome?

Answer 4

Once or a few times

Question 5

How much of the genome is Repetitive DNA?

Answer 5

60%

Question 6

What is unique DNA?

Answer 6

Protein coding, functional RNA, and regulatory regions (promoters, enhancers, introns, etc).

Question 7

How are unique sequences distributed?

Answer 7

Across all chromosomes

Some are denser than others

Question 8

What is repetitive DNA?

Answer 8

Satellite DNA, transposable elements, and gene families

Question 9

How is repetitive DNA distributed throughout the genome?

Answer 9

In two ways:
Interspersed
Tandemly repeated

Question 10

What is unique and repetitive DNA?

Answer 10

Unique DNA is present only once or a few times in the genome and includes protein coding, functional RNA, and regulatory regions (promoters, enhancers, introns, etc). Repetitive DNA makes up 60% of the human genome and is the same equence present multiple times in the genome. Repetitive DNA is distriuted in the genome as highly repetitive, tandem repeats, and interspersed repeats
