Answer:
Angiosperms evolved during the late Cretaceous Period, about 125-100 million years ago.

1.What is the probability that a sperm from the father will contain the PKU allele?
Probability = ½
2.What is the probability that an egg from the mother will contain the PKU allele?
Probability = ½
3.What is the probability that their next child will have PKU?
Probability = ¼ (because each parent has ½ chance ½ X ½ = ¼)
4.What is the probability that their next child will be heterozygous for the PKU gene?
Probability = ½ (because each parent has ½ chance of donating the ‘P’ allele and ½ chance of donating the ‘p’ allele (½ x ½) + (½ x ½) = ½
Answer:
May be Nutritional but no sure
Answer:
The correct answer will be- Golgi apparatus
Explanation:
The proteins are synthesized in the ribosomes whether they are attached to the endoplasmic reticulum or free. These synthesized proteins enter the lumen of the endoplasmic reticulum where they get packaged to go to Golgi apparatus.
The Golgi apparatus is the site of post-translational modification of the secreted proteins like ubiquitination, acetylation, phosphorylation and many others.
Thus, the Golgi apparatus is the correct answer.
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.
