Matching



This activity contains 2 questions.

Question 1.
Match the term with the definition.



A matching question presents 14 answer choices and 14 items. The answer choices are lettered A through N. The items are numbered 1.1 through 1.14. Screen readers will read the answer choices first. Then each item will be presented along with a select menu for choosing an answer choice. Using the pull-down menus, match each item in the left column to the corresponding item in the right column.
A The process of joining two complementary strands of DNA to form a double-stranded molecule.
B The outer layer of skin cells. These DNA-bearing cells often fall off or are rubbed off onto objects retrieved from crime scenes.
C A genetic locus useful for determining gender.
D Cells derived from the inner cheek lining.
E A technique for separating of molecules through their migration on a support medium while under the influence of an electrical potential.
F Abbreviation for deoxyribonucleic acid—the molecules carrying the body’s genetic information. DNA is double stranded in the shape of a double helix.
G The building blocks of proteins. There are twenty common amino acids. Amino acids are linked to form a protein. The types of amino acids and the order in which they’re linked determine the character of each protein.
H A rodlike structure in the cell nucleus, along which the genes are located. It is composed of DNA surrounded by other material, mainly proteins.
I A technique that simultaneously detects more than one DNA marker in a single analysis.
J Small structures located outside the nucleus of a cell. These structures supply energy to the cell. Maternally inherited DNA is found in each mitochondrion.
K The specific pairing of base A with T and base C with G in double-stranded DNA.
L The unit of DNA consisting of one of four bases—adenine, guanine, cytosine, or thymine—attached to a phosphate-sugar group.
M The total DNA content found within the nucleus of a cell. In humans, it is composed of approximately three billion base pairs of genetic information.
N Fewer than eighteen DNA-bearing cells.

Question 2.
Match the term with the definition.



A matching question presents 13 answer choices and 13 items. The answer choices are lettered A through M. The items are numbered 2.1 through 2.13. Screen readers will read the answer choices first. Then each item will be presented along with a select menu for choosing an answer choice. Using the pull-down menus, match each item in the left column to the corresponding item in the right column.
A An unstained object adjacent to an area on which biological material has been deposited.
B A short strand of DNA used to target a region of DNA for replication by PCR.
C The synthesis of new DNA from existing DNA.
D A region of a chromosome that contains multiple copies of a core DNA sequence that are arranged in a repeating fashion.
E Chemicals that act as scissors to cut DNA molecules at specific locations.
F Short tandem repeats located on the human Y chromosome. Their utility in forensic science is that they originate only from a male donor of DNA.
G A substance composed of a large number of atoms. These atoms are usually arranged in repeating units, or monomers.
H A region of a DNA molecule that contains short segments consisting of three to seven repeating base pairs.
I One-trillionth of a gram, or 0.000000000001 gram.
J Different fragment lengths of base pairs that result from cutting a DNA molecule with restriction enzymes.
K A procedure used to determine the order of the base pairs that constitute DNA.
L A technique for replicating or copying a portion of a DNA strand outside a living cell. This technique leads to millions of copies of the DNA strand.
M Polymers of amino acids that play basic roles in the structures and functions of living things.
