DNA And Cloning

Question 1

What is a gamete and what do they carry

Answer 1

Gametes are sex cells such as sperm and egg which carry genetic info

Question 2

What is a gene

Answer 2

Section of DNA, coding for the development of one characteristic

Question 3

Where is DNA carried in most cells

Answer 3

In the nucleus

Question 4

How can plants be cloned

Answer 4

Plants can be cloned by:

Cuttings:small section of plant is cut of and put in rooting powder.The plant is grown genetically identical to the parent

Question 5

How can cells be cloned using tissue culture

Answer 5

Small group of cells are removed and grown in a growth medium such as agar

Question 6

What is genetic engineering and how is it done

Answer 6

Genetic engineering is when genes of one animal are inserted into another. E.g. Human gene cut using enzymes and placed within DNA of bacterium

Question 7

What is mutation and what can it lead to

Answer 7

A mutation is a change in DNA or characteristics. This can lead to negative change, leading to evolution

Question 8

How can adult cells be cloned

Answer 8

Nucleus of adult cell removed, and nucleus of ovum removed. Original nucleus then inserted into ovum, resulting in clone of adult

Question 9

What are GM crops and the concerns

Answer 9

GM crops have been genetically engineered to have the best genetic make up so resistant to specific diseases, increasing yield.
Uncertainty on human health when GM crops are consumed

Question 10

Ethics of genetic engineering

Answer 10

Should we be playing God?

There has been no long term testing

Question 11

Ethics of cloning

Answer 11

Same gene pool so we all are affected by disease
