To produce a terminator nucleotide in Sanger DNA sequencing, a(n) ____ atom is removed from the hydroxyl group on the deoxyribos

jasenka [17]

Answer:

To produce a terminator nucleotide in Sanger DNA sequencing, a(n) oxygen atom is removed from the hydroxyl group on the deoxyribose sugar where it bonds with the adjacent phosphate group

Explanation:

DNA consists of a double helix made up of nucleotides.These nucleotides are arranged in such a way that each nucleotide has a phosphate group , a sugar and a nitrogenous base.

Sanger sequencing is a method of DNA sequencing which is actually based on the selective incorporation of the chain-terminating dideoxynucleotides by DNA polymerase during the DNA replication

The Sanger sequencing has following steps :

1) denature dsDNA using heat.

2) Make multiple copies of a segment.

3) Attach a primer.

4) Add to four polymerase solutions.

5) Grow complementary chains until termination dye.

6) Denature the grown chains.

7) Electrophorese the four solutions.

If a mother is type A and has a child who is type B what are the possible blood types of the father

jenyasd209 [6]

The possible father's blood groups are B, AB.

Explanation:

If the mother blood type of A, and the father blood type is AB, B then the child is B. Each biological parent donates one of their two ABO alleles to the child. The blood types in our body are classified as the four paternal blood types and the four maternal blood types.

The blood type has the 16 combinations of the blood samples. The genetic information from the body is independently inherited to the ABO blood types alleles. In the Rh factor, the genetic information is inherited from the one parent to another.
