Question 16

AB is

Answer 16

the universal recipient (AB+)

Question 17

O is

Answer 17

the universal done

Question 18

O has an

Answer 18

absence of antigens

Question 19

Rh Factor

Answer 19

+ or - that goes on the blood types.

A chemical on the surface of blood.

Question 20

Antigen

Answer 20

there are two antigens on blood, A and B

Question 21

Antibody

Answer 21

In plasma of blood against the opposite of the antigens you have.

So if you have A antigens, then you have B antibodies, and vice versa.

Question 22

AB has no

Answer 22

antibodies.

Question 23

O has

Answer 23

A and B antibodies

Question 24

+ can get

Answer 24

+ or - types

Question 25

- can only get

Answer 25

- types

Question 26

A+ can only get

Answer 26

A+, A- | O-. O+

Question 27

Gel Electrophoresis

Answer 27

is a technique that separates DNA molecules based upon their relative size to analyze different properties of genetic material

Question 28

Gel Electrophoresis is a method that

Answer 28

separates macromolecules such as DNA fragments on the basis of fragment size and the electrical charge of the molecule.

Question 29

In this technique (gel electrophoresis)

Answer 29

fragments of a DNA molecule are forced across a span of gel, motivated by an electrical current

Question 30

DNA molecules have a

Answer 30

negative electrical charge

Question 31

How are the DNA samples prepared?

Answer 31

A sample of DNA is taken from a person. Example: from blood or from an inner cheek cell swab. Restriction enzymes are added to the DNA in a solution.

Question 32

The restriction enzymes cut the DNA into fragments at specific ares called

Answer 32

restriction sites.

Question 33

the key to this process is this:

Answer 33

every human has restriction sites on their DNA molecules in different places. Which means that the fragments that my DNA is cut into will not match the size fragments that your DNA is cut into.

Question 34

Electrophoresis results:

Answer 34

the DNA fragments are loaded by pipette into loading wells formed in a gel. The gel is covered by a buffer solution and placed in an electric chamber. The electric current forces the charged DNA fragments to diffuse through the gel.

Question 35

Since small molecules diffuse more quickly than large ones,

Answer 35

the small DNA fragments will diffuse more quickly through the gel than the large ones. The DNA will appear as dark colored bands in the gel.

Question 36

Since each humans DNA will have been cut into unique size fragments,

Answer 36

then each persons DNA will have its own unique distinctive banding pattern in the gel.

Question 37

DNA gel electrophoresis can be used to

Answer 37

identify DNA from a crime scene and match it to a suspect. It can also be sued to identify the father of a child in cases of disputed paternity.

Question 38

clumping in blood indicates

Answer 38

antigen is present
