Sharp teeth that are constantly replaced would be the answer! In order for it to be a specific adaptation you would need the detail of why the animal has that adaption for example fins for stability:)
I believe it gives you the answer. It should be one fifth or 20%. #TeamAlvaxic
1. Contains their own DNA
2. Contains ribosomes that closely resemble prokaryotic cells
3. Reproduce by fission, and they are independent from cells.
A chromosome is DNA wrapped around proteins knwn as histones. A gene is a part of the DNA that codes for a particular protein
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.
