Give facts about the cytoplasm of an unfertilized egg
shusha [124]

Answer:

The cytoplasm of the egg cell is same as like that of the ordinary cell's cytoplasm.

It has yolk in its center which contains nucleus, nucleolus and germinal spot.

The mammalian ova contains a small amount of nutritive yolk which provides the nourishment to the embryo for a time being.

The cytoplasm of the unfertilized egg contains some unevenly distributed proteins, specifically the cytoplasmic determinants.

These determinants are the substances that plays a major role in the oocyte formation and maturation. Sometimes they are clumped together and then divided heterogenitically.

PLS HELP I WILL GIVE BRAINLIST
ra1l [238]

There are four bases found in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T). Adenine forms a base pair with thymine, and cytosine forms a base pair with guanine. There is a one-to-one relationship in these base pairings (Chargaff’s rule), which means that if you know the percentage of any one of them within a given DNA sample, you can calculate the percentages of the other three. In this case, you're given the percentage of guanine, and you want to find out the percentage of adenine.

Since guanine base-pairs with cytosine and since there must be as much cytosine as there is guanine, 41% of the bases in this gene are cytosine as well. That means that adenine and thymine <em>together </em>make up the remaining 18% (100% − 41% G − 41% C) of the base pairs. If there must be an equivalence in the number of thymine and adenine bases per Chargaff's rule, then half of the remaining base pairs must comprise adenine and the other half comprise thymine. Half of 18% is 9%.

Thus, adenine makes up 9% of the bases in this gene.
