The set of genes that control the expression of HLA is called

• the major histocompatibility complex.

• the panel reactive antibody.

• a haplotype.

• a serological match.

• a cross-match.

Rh factor refers to

• the ABO blood type system.

• a similar typing system to ABO.

• the presence or absence of an antigen on blood cells.

• is denoted by A, B or O.

• is denoted by + or -.

In a cross-matching test, a sign that the tissues of a donor and a recipient are compatible would be

• the absence of agglutination.

• the presence of agglutination.

• high levels of agglutination.

• a color change.

• a light flash.

The set of HLA antigens received from a parent is called a(n)

• histocompatibility.

• haplotype.

• panel reactivity.

• agglutination.

• match.

During PCR, what happens during the Denaturation step?

• DNA strands are separated according to size using gel electrophoresis.

• Primers form base pairs with the single-stranded template DNA.

• DNA polymerase adds new nucleotides to the primer to elongate the new strand.

• Hydrogen bonds between bases are broken using high heat to separate DNA strands.

Which of the following statements are true about DNA structure?

• The DNA backbone ("sides of the ladder") is made up of sugars and phosphates.

• The sugars and phosphates make up the unique code of each gene.

• The DNA backbone is the same for every person.

• Bases and sugars pair together to form the "rungs" of the DNA ladder.

• The sequence of bases is unique for each person.
