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.

Ms.Tim wants to find out how sleep affects students test scores.He organized two groups of students.In Group A, He has student s
Makovka662 [10]

Answer:

Independent Variable: Hours of sleep

Dependent Variable: Test scores

Experimental Group: Group A

Control Group: Group B

Explanation:

Hours of sleep is the independant variable because it is the factor being tested by the teacher. This is the factor that can be controlled.

Test scores is the dependant variable because it is the factor being affected by the changes in the independent variable. This is the variable being measured.

Group A is the experimental group because this is the one that has been altered or changed from what is normal.

Group B is the control group because nothing is being changed in this group but simply measured as a basis for comparison.
