The answer is an enzyme.
When cutting DNA, scientist uses enzymes called restriction enzymes. These enzymes are naturally produced in bacteria as a defense against phages. So, enzymes cut DNA of the phages and thus inactivate it. Also, these enzymes do not cat DNA randomly, but on specific sites. This characteristic of restriction enzymes is used for some molecular biology techniques. All species' DNA contains target sites of restriction enzymes, but most organisms do not have restriction enzymes. Therefore, restriction enzymes are suitable for different techniques.
Answer:
DNA
Explanation:
The nucleus is a central placed organelle in eukaryotic cells. It is said to contain the "blueprint of life" known as the DNA. The DNA is a structure located in the nucleus of the cell that encodes information necessary for the growth and development of the organism.
This information encoded by the deoxyribonucleic acid (DNA) of the cell includes how the organism will reproduce, hence, DNA is called the blueprint of life.
I am not entirely sure about this. So maybe my response can help you find the answer a little better if my answer is not entirely right?
These last three questions are referring to everything you just worked on. So all you would have to do is refer back to your previous answers. Recall that the titles of the "part 1, 2, and 3" are titled "crossing beak color and tail-feather length", "crossing beak color and feather color", and "mapping tail-feather length and feather color".
1.List the distances between each pair of genes:
beak color and tail-feather length: 20 MU
beak color and feather color: 16 MU
tail-feather length and feather color: 4 MU
2.Which two alleles are the farthest apart?
(the one that is 20 MU apart) Y and L
3.Which two alleles are the closest together?
(the ones that are 4 MU apart) L and B
