Answer:
The answer is letter A.
Explanation:
In virto fertilisation is a reproductive process, in which, embryos are produced after the extraction of the egg and the sperm from the childless couple.
First the woman is submited to a threatment to stop her menstrual cycle, then the doctor puts her under hormones threatment to estimulate her ovaries to develop follicles. After this step, a HCG is injected at her, so that the doctor can collect the eggs.
The man provide his semen after ejaculating in a dispenser. The physicians mix the egg and the semen and check if the fertilisation has been successful.
If the result is positive, the embryos are implanted inside of the woman's uterus.
After a few weeks the woman should take a pregancy test to confirm the pregnancy.

Explanation:
Answer:
mRNA that encodes multiple different polypeptide products
Explanation:
Polycistronic mRNA is a single molecule of mRNA that contains many genes, each one with its own start codon AUG, and therefore can be translated into many different polypeptides.
The polypeptide products usually have a related function, they can be either different subunits of a particular protein, or participate in a metabolic process.
Polycistronic mRNA is typically found in prokaryotes.
Answer:
The answer is mother in meiosis II
Explanation:
nondisjunction can be defined as the failure of the segregation of the child chromosomes in meiosis I and meiosis II resulting in gametogenes. This results in abnormal gametes with some chromosomal imbalance being formed and subsequent fertilization of these gametes results in a generation of abnormal individuals.
According to exercise, red-green color blindness follows an X-linked recessive pattern and the phenotype is only expressed. the father cannot bring the possibility of color blindness to his children, and the nondisjunction, defined earlier, cannot occur in either meiosis I or meiosis II. As a conclusion we can say that it may have a place in meiosis I or meiosis II corresponding to the mother and although the mother's condition may be normal, the first child would be compromised with color blindness, therefore, the mother is the carrier.
