Lesson 1.2 DNA Analysis

Question 1

Chromosome

Answer 1

Any of the usually liner bodies in the cell nucleus that contain the genetic material

Question 2

Cytosine

Answer 2

A component of nucleic acids that carries hereditary information in DNA and RNA In cells. Chemically, it’s a pyrimidine base.

Question 3

ADENINE

Answer 3

A component of nuclear acids, energy-carrying molecules such as ATP, and certain coenzymes. Chemically, it is a purine base.

Question 4

Deoxyribonucleic acid ( DNA )

Answer 4

A double-stranded, helical nucleic acid molecule capable of replicating and determining the inherited structure of a cells proteins

Question 5

Gel electrophoresis

Answer 5

The separation of nucleic acids or proteins, on the basis of their size and electrical charge, by measuring their rate of movement through an electrical field in a gel.

Question 6

Gene

Answer 6

A discrete unit of heredity information consisting of a specific nucleotide sequence in DNA ( or RNA, in some viruses )

Question 7

Guanine

Answer 7

A component of nucleic acids that carries heredity information in DNA and RNA in cells . Chemically, it is a purine base .

Question 8

Helix

Answer 8

Something spiral in form

Question 9

Model

Answer 9

A simplified version of something complex used, for example, to analyze and solve problems or make predictions

Question 10

Nucleotide

Answer 10

A building block of DNA, consisting a five-carbon sugar covalently bonded to a nitrogenous base and a phosphate group

Question 11

Restriction enzyme

Answer 11

A degradative enzyme that recognizes specific nucleotide sequence and cuts up DNA

Question 12

Restrictions fragment length polymorphisms

Answer 12

Differences in DNA sequence on homologous chromosomes that can result in different patterns of restriction fragment lengths (DNA segments resulting from treatment with restriction enzymes )
