HEREDITY

3
Q

are composed of smaller units called genes (DNA)

A

CHROMOSOMES

4
Q

A gene’s specific position along a chromosome is called

A

LOCUS

5
Q

PAIRS OF GENES that carry the same traits and are located at the same place on pairs of chromosomes

A

ALLELES

6
Q

The simple addition, deletion, or manipulation of a single trait in an organism to create a desired change

A

GENETIC ENGINEERING

7
Q

Artificially copying a piece of DNA from one organism and joining this copy of DNA into the DNA of another organism

A

GENETIC ENGINEERINH

8
Q

It allows genes from one organism to be inserted into a cell of a different organism of a different species

A

GENETIC ENGINEERING

9
Q

The altered DNA is called

A

RECOMBINANT DNA

10
Q

This is where tiny segments of a gene are taken out and
replaced by different genes

A

GENE SPLICING

11

Is a stretch of DNA that codes for a type of protein that has a function in the organism

A

GENE

17
Q

It is a UNIT OF HEREDITY in a living organism. All living things depend on it

A

GENE

18
Q

these HOLD THE INFORMATION to build and maintain an organism’s cells and PASS GENETIC TRAITS to offspring

A

GENE

19
Q

The EXCHANGE of corresponding DNA segments between adjacent chromosomes during the special type of cell division that RESULTS IN THE PRODUCTION OF NEW GENETIC MAKE UP

A

RECOMBINANT

20
Q

In genetic engineering, recombination can also refer to artificial and deliberate recombination od pieces of DNA, from different organism, creating what is called __________

A

RECOMBINANT DNA

GENE PHRAMING

30
Q

One of the first mammals engineered successfully for the purpose of pharming was a sheep born in 1990and created by scientist led by British developmental biologist Ian Wilmut at Roslin Institue in Scotland.

32
Q

Is the transplantation of living cells, tissues, or organs from on species to another

A

XENOTRANSPLANTATION

33
Q

It involved modifying human DNA either to repair it or to replace a faulty gene
* The idea of this is to overcome the effects of a mutation which causes a genetic disease
* Cystic fibrosis is the best-known disease where this has been tried

A

GENE THERAPY
