Examples of proliferative cells in the body

Back 1

Skin fibroblasts

SMooth muscle cells

Endothelial cells that line blood vessels

Epithelial cells of most internal organs

Front 2

Pyrimidines

Back 2

Front 3

Which amino acid contains a sulfhydryl?

Back 3

Cysteine

-SH

Front 4

Inhibition of phosphofructokinase-1 by ATP is an example of what kind of inhibition?

Back 4

Allosteric and Feedback inhibition

Front 5

A transcription factor must contain what kind of signal?

Back 5

Nuclear localization sequence

Front 6

Ubiquitination

Back 6

can affect proteins in many ways: it can signal for their degradation via the proteasome, alter their cellular location, affect their activity, and promote or prevent protein interactions.

Front 7

Proteasome

Back 7

Breaks down "garbage" protein

Completely degrades it

Different from protease which just hydrolyzes bond

Front 8

If a protein becomes denatured and inserted into the inner membrane of mitochondria:

Back 8

Choose answer: proton gradiant across inner membrane will dissipate

(not ETC will cease)

Front 9

GAPDH - Glyceraldehyde 3 phophate dehydrogenase

Back 9

Catalyzes glyceraldehyde 3 phosphate ---> 1,3 biphosphoglycerate

Front 10

What is the best test to use to measure posttranslational modification of proteins (e.g. histone acetylation)

Back 10

Western blot

Front 11

Southern Blot

Back 11

DNA

Front 12

Northern blot

Back 12

RNA

Front 13

Vasopressin

Back 13

Regulates fusion of aquaporins with apical membranes of collecting duct epithelial cells

ADH - increase H20 permeability

Front 14

Apical membrane

Back 14

Membrane of polarized cells - surface of membrane that faces inwards to the lumen

Front 15

If bacteria enters the blood stream from the small intestine, which will be the first major organ that it will encounter

Back 15

LIVER

-Blood from small intestine is transported first to liver, which regulates nutrient distribution and removes toxins form the blood

Front 16

How to find percent increase or decrease of two numbers

Back 16

Front 17

Compared to the WT, a mutation resulting in the addition of a nucleotide (not effect stop codon) will result in:

Back 17

Both will have the same amino terminal, but different primary carboxyl terminal sequence

(since another nucleotide is added)

N->C

Front 18

Malate, Succinate, alpha-ketoglutarate

Back 18

Produced during Krebs cycle

Front 19

Centromere vs centrosome

Back 19

Centromere: Part of chromosome that links sister chromatids

Centrosome: Cell organelle, center for microtubule organization

Front 20

Kinetochore

Back 20

Complex of proteins associated with centromere of chromosome during cell division, to which microtubules of spindle attach.

Front 21

Microtubules originate from ________ for cellular transport

Back 21

Centrosome

Front 22

T cell receptors from cytoxic T lymphocytes target:

Back 22

CTL target viral antigens presented on the surface of the virus infected cells

Front 23

Which regions are highly specific?

Back 23

Regions 1 and 3 are the variable portion of the light an heavy chain

antigen recognition

Front 24

Where in the human male reproductive system do gametes become motile and capable of fertilization?

Back 24

Sperm is produced in seminiferous tubules of testes, completes maturation and becomes motile in the epididymis

Front 25

______ is required to break the bond between actin filament and myosin head
