postnew [5]

Answer:

There should be 10% thymine

Explanation:

DNA bases come in specific pairs. Guanine pairs up with cytosine and adenine pairs up with Thymine.

According to the problem the DNA sample was 40% cytosine and 40% guanine, so this is correct, there are equal amounts of cytosine and guanine. Now Thymine needs to have equal amounts as adenine, but adenine only has 10%.

If we match up the amount of adenine to thymine, we would have 15% adenine and 15% thymine, but that would excede 100%. So you need to match the thymine to adenine.

10% adenine + 10 % thymine + 40% cytosine + 40% guanine = 100%

love history [14]

Answer:

Chorionic villus sampling

Explanation:

Chorion is one of the extraembryonic membranes that surround the fetus and the amniotic cavity. The cells present in the chorion have the same genome and chromosomes as present in the fetus. Therefore, some of the chorionic tissues are collected from the chorionic villi. These tissues are then analyzed for any chromosomal abnormality. This process is called chorionic vill sampling. For the purpose, tissue collection can be done by inserting a catheter through the cervix or using a needle through the uterine wall.
