Sonbull [250]

Answer:

Delivered small RNAs can inhibit protein A production through the RNA interference (RNAi) mechanism, and thus impairs angiogenesis  

Explanation:

The pregnancy-associated plasma protein-A is a protease enzyme involved in the formation of new blood vessels by increasing insulin-like growth factor I (IGF-I) bioavailability. Moreover, small RNAs (<200 nucleotides in length, generally 18 to 30 nucleotides) are non-coding RNA molecules that function in RNA silencing through the RNA interference (RNAi) pathway. Small RNAs are widely used in molecular biology laboratories because they can be delivered into specific cells in order to silence target mRNAs such as, in this case, the mRNA encoding protein A, by complementary base pairing and thereby inducing translational repression. In consequence, mRNAs complementary to delivered small RNAs are silenced through RNAi pathways, i.e., by cleavage of the target mRNA and/or mRNA destabilization.

PLS SOMEONE DRAW ME Punnett square FOR THIS ASAP,
allochka39001 [22]

Answer:

Punnett square drawn below:

Explanation:

Sorry if it's messy. Since brown coat is dominant to black coat, that would mean that the genotype for brown is either Aa or AA. Since it says it's a pure breeding brown mouse and that all of the offspring are brown, that means that the genotype for the pure breeding brown mouse is AA. As for the black coated mouse, black is reccessive, meaning the genotype would be aa. So... AA x aa = 100% Aa
