Answer:

B. misalignment of the chromosomes during anaphase I

Explanation:

Aneuploidy refers to an error in the chromosomal number of a cell. This occurs when the chromosomes fail to separate equally into individual cells, a process called MEIOTIC NONDISJUNCTION. Meiotic disjunction can occur in either the anaphase stage of meiosis I or meiosis II, however, different outcomes are produced.

When chromosomes fail to separate at meiosis I, it results in two gametes that lack that particular chromosome (n-1) and two gametes with two copies of the chromosome (n+1). This means that the four daughter cells will have an incorrect number of chromosomes, hence, the misalignment of the chromosomes during anaphase I will result in four aneuploid daughter cells.

What is semi-conservative DNA replication and how does it differ from conservative replication? Which type of DNA replication is
fredd [130]

Answer:

Semi-conservative DNA replication:

The semi-conservative model of DNA replication explains that the newly synthesized daughter DNA molecule contains one newly synthesized strand and one parental strand. This model of replication is important and explains the biological significance of replication. The DNA unwinds in this mode of replication.

Conservative model of DNA replication:

The conservative model of DNA replication explains that the newly synthesized daughter DNA molecules has the one DNA helix of parent and the other DNA helix are entirely new. This model does not has a biological significance. The DNA is not unwinds in this mode of replication.

The semi-conservative mode of DNA replication is found in the living organism.

Now that you have identified the components of DNA, can you describe how these components bind together to form a DNA molecule?
omeli [17]

The question is incomplete. The complete question is attached below.

Answer:

1. DNA is the polymer of deoxyribonucleotides that contain the nitrogenous base, pentose sugar and phosphate group. The phosphate is attached with the 3 C position of the deoxyribose sugar. This leads to teh formation of phosphodiester bond.

2. The DNA backbone consists of phosphate and sugar. The nitrogenous bases are inserted inside the DNA molecule. These nitrogenous bases are linked together by the hydrogen bonds.

3. The adenine binds requires two hydrogen bonds to bind with thymine. This provide complementary nature to the DNA molecule. Uracil is present instead of thymine in RNA .

4. The guanine binds requires three hydrogen bonds to bind with cytosine. More amount of energy is required to break their bonds.
