If adenine didn’t always pair with thymine and guanine didn’t always pair with cytosine, the new DNA ladders wouldn’t always be
zloy xaker [14]

Answer:

they wouldnt be identical because for example Guanine could be paired with thymine in the original DNA strand but could decide to pair with adenine in the replication DNA. that would make a different type of DNA.

Explanation:

DNA replication is a beautiful process. In DNA replication adenine only pairs with thymine and guanine only pairs with cytosine. this ensures that a replication of the DNA will be the same type of DNA.

Replication works like this. Helicase splits open the DNA and each side is copied by DNA polymerase. If let's say the nucleotide bases for side 1 are ATGCGA then the DNA polymerase will pair these with the matching bases TACGCT which will make the same DNA but if each base could pair with any base they want that could create a few different variations of the original DNA. ATGCGA could very well be paired with TCGACA or CGACTA which would created two different types of DNA.

Wilma and Stanley are expecting their first child, and a prenatal test indicates that the child has a chromosomal abnormality. T
rodikova [14]

Answer:

The cells analyzed might be a mosaic of different genomes

Explanation:

The human genome in every cell might not be the same and could give us some misrepresentation of what really happens on our genome. Chromosomal abnormalities are also a very common phenomena to be observed in human cells. For those differences in the genome of the child the test might have identified some altered cells with a type of chromosomal abnormality which was not latter identified or the abnormal cell might be also eliminated by its abnormal nature.
