Answer:
Melanin helps the mouse survive because of the fur color. Its color helps it to blend into its surroundings, making it a lot harder for predators to kill it, as the predators have a harder time seeing the mouse.
Explanation:
they are strongest between latitudes of 30°N and 60°N. but they move every year, "following the sun".
Answer:
sigma subunit
Explanation:
Sigma subunit of RNA polymerase holoenzyme directs the enzyme towards the consensus sequences present upstream of the transcription start site. Completion of the initiation phase of transcription is followed by dissociation of sigma subunit from the transcription complex.
The protein NusA replaces the sigma subunit. The RNA polymerase leaves the promoter and starts the elongation
.
Answer:
Living
Explanation:
To function the brain send out signals to optimize and regulate the body and that's what makes you a living organism
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.
