4.02 FOA DNA and Biotechnology in Animal Science

Front

What is a chromosome?

Back

A structure that holds the genetic information of a cell.

Front

What is DNA?

Back

Deoxyribonucleic acid, the coded material in all cell nuclei that determines what that cell and its successive cells will become. Its structure is a double helix.

Front

What is a gene?

Back

A small section of DNA.

Front

What is gene mapping?

Back

The process of both finding and recording the locations of genes.

Front

What are bases in DNA?

Back

Bases are like rungs of a ladder that hold the two sides of the DNA strands together. They include Adenine (A), Thymine (T), Guanine (G), and Cytosine (C).

Front

Which bases pair together in DNA?

Back

Adenine (A) pairs with Thymine (T), and Guanine (G) pairs with Cytosine (C).

Front

What is the significance of the sequence of bases in DNA?

Back

The sequence of the bases between the DNA strands is the code by which a gene controls a specific trait.

Front

What is animal cloning used for in biotechnology?

Back

Animal cloning is used for product uniformity, saving endangered species, and research purposes.

Front

What is BST in animal science?

Back

Bovine somatotropin, a hormone produced in the pituitary gland of cattle that increases milk production.

Front

What is artificial insemination (AI)?

Back

The introduction of male sperm into the reproductive tract of a female by means other than natural mating.
