Answer:

The XY chromosomes refer to the gender chromosomes and a mutation to where a child is born with XXY chromosomes would mean that the child Would have Klinefelter syndrome. A child with XX chromosomes is a female and a child with XY chromosomes is a male. The mutation has an extra gamete.

I hope this helps! :)

The germ cell has 2 sets of chromosomes, and the four gametes will each have one set of chromosomes. To have enough DNA

ICE Princess25 [194]

Answer:

This question lacks options, the options are:

A. Halved

B. Doubled (x2)

C. Quadrupled (x4)

D. Octupled (x8)

The answer is B.

Explanation:

Via the process of meiosis, gametes are formed in order for sexual reproduction to occur. However, the chromosomal content of the gametes are reduced by half. According to this question, a germ cell is said to have 2 sets of chromosomes i.e. diploid, meaning that each daughter cell after meiosis will have one set of chromosome (haploid, n).

However, before any form of division can occur, the DNA (genetic material) of the cell must be replicated i.e. doubled in order to ensure that each resulting gamete has enough chromosomes. This is applicable in this question as well as the DNA in the germ cell must be DOUBLED (×2) via replication in order to have enough DNA for each gamete.

What is the sequence of the mrna made from the gene aaacaggtccca?

olga nikolaevna [1]

<span>The mRNA is made by using the gene AAACAGGTCCCA as a template for complementary base-pairing. The pairings are: G (Guanine) to C (Cytosine), C to G, T (Thymine) to A (Adenine), and A to U (Uracil, as Tyhmine doesn't occur in the RNA). The resulting mRNA is UUUGUCCAGGGU.</span>
