Fundamentals Of Cell Bio Pt. 2

Front 1

Sodium potasium pump

Back 1

every 3 Na+ pumped out of the cell, 2 K+ are pumped in. a cell can use 1/3 of its energy to maintain this balance.

Front 2

cellular cytoskeleton

Back 2

maintains cell shape. aids in transportation and communication.

Front 3

mitochondria

Back 3

power house of cell

Front 4

packages molecules to be exported from the cell

Back 4

golgi apparatus

Front 5

ribosomes

Back 5

site for protein synthesis

Front 6

contains cellular dna

Back 6

Nucleous

Front 7

site for photosynthesis

Back 7

chloroplasts

Front 8

lysosomes

Back 8

cells "garbage disposal"

Front 9

nucleolus

Back 9

Area in nucleous where rRNA is made

Front 10

molecule that gathers photons of light

Back 10

chlorophyll

Front 11

Enzyme

Back 11

biological catalyst

Front 12

reactants in enzyme reaction

Back 12

substrate

Front 13

eukaryotic vs. prokaryotic structure

Back 13

eukaryotes are compartmentalized(specific organells for specific celular functions.) ... prokaryotes have cell wall. eukaryotes have nucleous.

Front 14

describe plasma membrane

Back 14

Fuck That Shit Bitch

Front 15

DNA replication requires:

Back 15

DNA + RNA nucleotides

Front 16

synapsis occurs durring

Back 16

prophase I

Front 17

In the Go stage of the cell cycle, cells divide....

Back 17

do not divide

Front 18

When the product of one gene influences the activity of another gene this is called:

Back 18

Epistasis

Front 19

Mutations can occur from:

Back 19

Additions or deletions

Front 20

The fact that 1/2 of the genetic information of the offspring of sexually reproducing organisms comes from each parent is the result of:

Back 20

Segregation

Front 21

DNA synthesis is discontinuous on the ___ strand

Back 21

lag

Front 22

The founder of modern genetics:

Back 22

Gregor Mendel

Front 23

cell cycle-

Back 23

stages through which one cell passes between one division and the next. includes all stages of interphase and mitosis.

Front 24

crossing over

Back 24

occurs in prophase I when chromesomes become intertwined. This exchange of genetic info increases diversity.

Front 25

linkage group

Back 25

Example....The body color gene and the wing size gene were not assorting independantly but were inherited together.

Front 26

kinase

Back 26

enzyme that transfers a phosphate group from ATP to another molecule.

Front 27

mitosis vs. meiosis

Back 27

Mitosis occurs in all organisms while meiosis occurs in humans animals plants and fungi.
Mitosis produces 2 daughter cells while meiosis produces 4.

Mitosis-asexual reproduction...meiosis-sexual.
Mitosis produces 2 diploid daughter cells...meiosis produces 4 haploid.
Meiosis- crossing over occurs

Front 28

Cell contains 2 complete sets of chromesomes

Back 28

diploid

Front 29

Heterozygote is intermediate to both homozygotes

Back 29

incomplete dominance

Front 30

Haploid

Back 30

cells contain 1 complete set of chromesomes

Front 31

genes are located on different chromesomes

Back 31

independant assortment

Front 32

test cross

Back 32

cross done to determine if parent is homozygous or heteroygous

Front 33

trait expressed in homozygous or heterozygous individuals

Back 33

dominant

Front 34

trait which is only expressed in a homozygous individual

Back 34

recessive

Front 35

why are X-linked recessive traits more commonly seen in males that in females?

Back 35

women have 2 X chromesomes while men only have 1. Therfore the cross between the two often result in incomplete dominance.

Front 36

What is RNA primers role in DNA replication?

Back 36

readys each base for replication.
