Answer:
mRNA is “messenger” RNA. mRNA is synthesized in the nucleus using the nucleotide sequence of DNA as a template. This process requires nucleotide triphosphates as substrates and is catalyzed by the enzyme RNA polymerase II. The process of making mRNA from DNA is called transcription, and it occurs in the nucleus.
Yes, an amniocentesis is necessary.
While both the woman and the husband may not exhibit sickle cell anemia, they could be carriers of the sickle cell recessive gene. If she is heterozygous for sickle cell allele, because of her father, and the man has no recessive gene, then the child has no chance of exhibiting the disease but has a 0.5 chance of being a carrier.
However, if the man is also a carrier, the child has a 0.25 probability of having sickle cell anemia.
