Correct question:
if a nondisjunction occurs at anaphase I of the first meiotic division, what will the proportion of abnormal gametes (for the chromosomes involved in the nondisjunction)?
Answer:
100%
Explanation:
Nondisjunction at meiosis-I means that two homologous chromosomes of at least one homologous pair fail to separate from each other during anaphase-I. This would result in the formation of one cell with one extra chromosome and the other with one less chromosome by the end of meiosis-I. Meiosis-II in these two cells would maintain this chromosome number in the daughter cells. Therefore, out of the total four gametes formed by the end of the meiosis, two would have one extra chromosome and would be denoted as "n+1". The rest of the two gametes would have one less chromosome and would be denoted as "n-1".
Answer:
Option (A).
Explanation:
Estrogen hormone is important for the regulation of the female menstrual cycle and their growth and development. Insulin is an important hormone that regulates the blood glucose level.
The hormones insulin and estrogen is placed in the mixture of 2:1 hexane/water. Insulin is hydrophilic molecule and can easily dissolce in water. Estrogen is a hydrophobic molecules and easily dissolve in hexane.
Thus, the correct answer is option (A).
The characteristic of bacteria that makes them efficient transgenic organisms to produce insulin or other medicines is they readily accept new genetic material.
<h3>What do you mean by Transgenic organisms?</h3>
Transgenic organisms may be defined as an organism whose genome has been modified by the insertion of one or more foreign (non-self) DNA sequences from another species via artificial means.
A Plasmid is a circular DNA that assists in the insertion of foreign DNA sequences into the bacterial cell.
Therefore, the characteristic of bacteria that makes them efficient transgenic organisms to produce insulin or other medicines is they readily accept new genetic material.
