-transgenic animal

Question 2

what is stomatic cell nuclear transfer

Answer 2

cloning

Question 3

how is cloning done

Answer 3

-somatic body cell with desired genes is acquired
-and a nucleus is removed form egg cell
-nucleus is fused with denucleated egg cell

Question 4

Answer 8

-microinjection
-viral infection
-electroporation
-transfection

Question 9

whats CRISPR

Answer 9

-bacterial defence mechanism that cuts up viral DNA
-modified to cut the DNA at a specific spot on any genome in any cell/embryo
-can disrupt a gene or insert a new nucleotide of whole new gene where that DNA was cut
