Mitosis is important<span> because it is essential for growth and repair in the </span>body<span>. </span>Mitosis<span> happens when a parent cell divides, creating two identical copies, referred to as daughter cells. During this process, it is essential that the daughter cells are exactly the same with the same copies of DNA.</span>
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:
Freshwater is a precious resource on the Earth's surface. It is also home to many diverse fish, plant, and crustacean species. The habitats that freshwater ecosystems provide consist of lakes, rivers, ponds, wetlands, streams, and springs.
Light excites the electron in the electron transport train and once it goes down the train water replaces the missing electron. the electron transport chain brings it down, hydrogen gets pumped across then when it slides back down the other side, energy is created. chlorophyll is the goo stuff that lets it absorb the light. carbon dioxide goes into the calvin cycle and it rearranged uses energy from the first part. the products of this part is sugar (C6H12O6) and oxygen.
water and carbon dioxide go in, oxygen and sugar come out
