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.
Answer:
A meter is a metric unit of length used worldwide by scientists to measure lengths and distances between objects.
<span>B) Plant-based diets are usually lower in saturated fat and higher in fiber, which reduces risk of heart disease.
Saturated fats increase the risk for heart disease, so they should be kept lower. Fiber may help reduce overall calorie intake by keeping you full for longer. That way you maintain a healthy weight, which is important for</span><span> reducing </span>cancer<span> risk.</span>
I believe the answer is D) all cells are produced from other cells
it divides organelles so don't they run into each other
