The correct answer is:

(A) In metaphase I, tetrad sets of homologous chromosomes stay together as they line up along the center of the cell.

Explanation:

In meiosis, homologous chromosomes pair with each other (i.e., they form tetrads) and crossing-over occur. In mitosis, not of these things occur. In metaphase I of meiosis, tetrads follow on the metaphase plate. In mitosis, there is only one state and it creates two daughter cells

Answer:

It contains Uracil (U) instead of Thymine (T).

Reason for primer removal:

This is because of their uracil nucleotide which is absent in DNA. Instead of Uracil DNA contains Thymine nucleotide.

Explanation:

Primers:

Primers are a short sequence of RNA. These sequences attached to the 5' end are the requirement of DNA polymerase to start the process of replication.

Primer removal:

After replication, these short fragments of RNA are removed to replaced with DNA from the newly synthesized DNA strand.

Reason for primer removal:

This is because of their uracil nucleotide which is absent in DNA. Instead of Uracil DNA contains Thymine nucleotide.

Best Answer:

Because It contains Uracil (U) instead of Thymine (T).
