The researchers introduced a small RNA complementary to a portion of the mRNA encoding protein A into the Brec-MUT cells growing

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.

What is the probability that each of the following pairs of parents will produce the given offspring: 1. AABbCc x aabbcc à AaBbC

ICE Princess25 [194]

Answer:

1) AaBbCc, 50% - 2) AAbbCC, 3,125% - 3) AaBbCc is 12,5%.

Explanation:

1º cross.

Parental) AABbCC x aabbcc

Gametes) ABC AbC ABC AbC ABC AbC ABC AbC

abc abc abc abc abc abc abc abc

Punnet Square) Only filled with the progeny genotype AaBbCc.

ABC AbC ABC AbC ABC AbC ABC AbC

abc AaBbCc --- AaBbCc --- AaBbCc --- AaBbCc ---

F1 Genotype) 32/64 AaBbCc

32/64 AabbCc (shown as the symbol "---" in the

punnet square)

The probability of producing offspring with genotype AaBbCc is 50%.
