Small interfering rna, also known as rnai, is single-stranded rna that binds to mrna with a rna-induced silencing complex protein. according to the model, what is the most likely effect of rnai on the expression of the mrna? a) rnai degrades the mrna, preventing its translation. b) rnai increases the transcription of the target gene. c) rnai increases the translation of the specified mrna. d) rnai degrades the protein, preventing its phenotypic expression.

I believe the correct answer is A.) RNAi degrades the mRNA, preventing its translation.

Explanation:

This is because when RNAi degrades mRNA, it connects to the strand of mRNA and breaks it apart. The ribosomes then have to salvage the bits of the mRNA strand that remain.

the correct answer is b. possesses the characteristic of compartmentalization of organelles, wherein the organelles are bound by membranes.

explanation:

lizards have adapted to life in the desert. some desert lizards have toes with spiny scales to them run across the sand without sinking. some use the sand to hide from predators, or to search for small animals that they prey upon.
