Question 1

In humans sex chromozones are know as either x or y chromozones

Answer 1

True

Question 2

All stem cell reserch requires taking a human life

Answer 2

False

Question 3

If a gene for a sex linked trait is located on the x chromozone; then its only females that will get this trait

Answer 3

Flase; males do have an X chromosome

Question 4

In medelians gentics a dominate trait gets masked by a ressesive trait

Answer 4

False; a dominate trait masks a resive trait

Question 5

Mitosis results in 4 daughter cells with idential DNA

Answer 5

False; 2 daughter cells

Question 6

All cells contain DNA

Answer 6

True

Question 7

DNA contains regions that are called genes

Answer 7

True

Question 8

The sequence of genes and its instrustions have everything to do with the coding for protines

Answer 8

True

Question 9

Groups of specialized cells use protines to carry out funtions that are essential to the orginism

Answer 9

True

Question 10

All cells contain DNA and all cells do contain genes that can code for the formation of protines

Answer 10

False; Red blood cells

Question 11

Body tissues are systems of specialized cells with similar structures and funtions each of whoes funtions are mainly carried out by the protines they produce.

Answer 11

True

Question 12

Proper functioning of protines is reated to the proper functioning of cellls

Answer 12

True

Question 13

Gene sequence affects protine function which then affects the funtioing of the body tissuess

Answer 13

True

Question 14

Each chromozone consits of a single very long DNA molecule and each gene on the chromozone is a particular segment of the DNA

Answer 14

True

Question 15

The instructions for forming species chraraterisits have very much to do with the DNA

Answer 15

True

Question 16

All cells in an orginisum have the same gentic content but the genes expressed by the cell may be regulated in diffrent ways

Answer 16

True

Question 17

Not all DNA codes for a protine some segments are involved with structual functions and some are unknown
(Not all DNA codes do the same funtions)

Answer 17

True

Question 17

Our body cells contain gentic material containg 2 varients of each chromozone pair ( one from each parent)

Answer 17

True

Question 18

Multicellular orginisms are a collection of diffrent cells

Answer 18

True

Question 19

After mitosis daughter cells resive identical gentic information from a parent cell

Answer 19

True

Question 20

Mitotic cell divison dose produce 2 geneticly identical daughter cells from one parent cell

Answer 20

True

Question 21

Diffrences between cell types within a multicelluar organism are due to gene expression not genetic material within that orginism

Answer 21

True

Question 22

Cell mitosis allows for the groth of the organism and replace dead cells or damages cells

Answer 22

True

Question 23

Durring sexual reproduction chromozones swap sections of the chromosome durring meiotis

Answer 23

True

Question 24

Crossing over creates new gentic combonations and thus more gentic variation

Answer 24

True

Question 25

Although DNA replacation beofre meitosis is acurate errors can occur and this can lead to gentic variation

Answer 25

True

Question 26

Enviromental factors can affect expresion of traits and the probibilty of the occurances of traits in a population

Answer 27

True

Question 28

Gentic variations produced by mutation and meiosos can be inherited

Answer 28

True

Question 29

All organisms have the same number of chromosomes

Answer 29

All organisms have the same number of chromosomes

Answer 30

False
