Quiz 1 Last year

Question 1

Mitochondria

Answer 1

Serve as the source of energy production for the cell. The mitochondria also contain a small amount of extra-genomic DNA (maternally contributed)

Question 2

Promoter

Answer 2

DNA sequence to which the transcription apparatus (RNA pol) binds to initiate transcription

Question 3

Transcription Factor

Answer 3

A protein that can regulate the rate of transcription of a gene by interacting with a DNA sequence that may or may not be near the gene

Question 4

Stratified epithelium

Answer 4

More than one layer of epithelial cells

Question 5

Cytoskeleton

Answer 5

consists of proteins that provide dynamic structural framework for the cell and can effect cell shape, locomotion, intracellular transport, and gene expression

Question 6

Four types of cell hormone communication

Answer 6

endocrine
intracrine
paracrine
autocrine

Question 7

Endocrine

Answer 7

Through the blood

Question 8

Intracrine

Answer 8

Acts on the same cell without secretion

Question 9

Paracrine

Answer 9

Stimulates adjacent cell without entering the blood

Question 10

Autocrine

Answer 10

Stimulates the same cell but is secreted first

Question 11

What is the difference between induced and spontaneous ovulation? give an example of each

Answer 11

Induced-ovulation happens after stimulation-cat
Spontaneous-ovulations happens every cycle-human

Question 12

How testosterone secretion/level is regulated by the hypothalamus and anterior pituitary gland

Question 13

describe how steroid hormones are deactivated and made water soluble for excretion in the urine and feces

Question 14

Describe how a transcription factor activated DNA and the pathway to the production of a protein in a tissue
