Hopefully these are correct
Answer:
The nucleus shrinks in size
The probability of producing a transgender = None ( D ) when the father is gay
The probability of producing male gamete is not affected by the sexual orientation of the Father because the production of the male gamete is carried by the spermatogonia found in the testes of a male. and every male specie regardless of your sexual orientation have testicles where the spermatogonia undergoes mitotic divisions to produce the male gametes.
Hence the probability of producing a transgender given that the father is gay is non-existent i.e.0%

Answer:
C) binding to mRNAs and degrading them or blocking their translation
Explanation:
<u>miRNAs:</u>
miRNAs is the abbreviation of MicroRNAs. These are the small noncoding RNAs of ∼22 nucleotides which can not code for peptides. miRNAs are responsible for gene expression regulation at the level of post transcription. They can do so by forming complementary base pairing with target mRNA and inhibiting their translation.
They silenced mRNA by the following processes:
(1) Cleavage of the mRNA strand into pieces,
(2) stopping mRNA from translation into proteins by ribosomes.
(3) Shortening of mRNA poly(A) tail and destabilizing it.
