Answer: D- Dicer
Explanation:
Dicer, also known as endoribonuclease Dicer or helicase with RNase motif, is an enzyme that in humans is encoded by the DICER1 gene. Being part of the RNase III family, Dicer cleaves double-stranded RNA (dsRNA) and pre-microRNA (pre-miRNA) into short double-stranded RNA fragments called small interfering RNA and microRNA, respectively. These fragments are approximately 20-25 base pairs long with a two-base overhang on the 5' ends. Dicer facilitates the activation of the RNA-induced silencing complex (RISC), which is essential for RNA interference. RISC has a catalytic component Argonaute, which is an endonuclease capable of degrading messenger RNA (mRNA).
<u>Answer:</u>
Jack is correct because a solution is not a type of mixture because the substances stay mixed together and cannot be separated. Each substance loses its primary physical properties.
Option: (D)
<u>Explanation:
</u>
- A mixture is composed of 'two or more different substances', physically combined and it is in the form of a solution, suspension or a colloid.
- A mixture may be homogeneous (salt and water) or heterogeneous (sand and water).
- A homogeneous mixture of two or more compounds is termed as solution. It has a solute and a solvent.
- The 'solute' is the substance dissolved in the solvent. Both lose their primary physical properties.
