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

in a petri dish. The researchers claim that the treated cells will fail to stimulate blood vessel formation. Based on information provided, provide reasoning to support their claim.

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.

Explain the cellular functions that occur when antibiotics attack a bacteria cell.
Alex73 [517]
That would be A.

Most antibiotics that are used for gram positive bacteria target the peptidoglycan cell wall, but the ones for gram negative bacteria are more advanced and specific and target the cell membrane and alter the cell’s function(processes of proteins and dna/gene expression).

Why do so many (~30%) gorilla babies die within the first few months of their lives?
katrin2010 [14]

(30%) gorilla babies die within the first few months of their lives because of inherent weakness of the infant or disease.

What is inherited disease?

Genetic factors play a role in almost all health conditions and traits, but there are some conditions in which genetic alterations play a role in almost all of the causes that cause the condition.

Genes are passed from parent to child, so are DNA changes within the gene. DNA changes can also occur spontaneously, first appearing in children of unaffected parents. This is called a new mutation, and the word mutation means change.

Therefore, (30%) gorilla babies die within the first few months of their lives because of inherent weakness of the infant or disease.

Gene flow _____.
nikitadnepr [17]

Answer: The correct answer for the blank is-

evens out genetic differences between populations

Gene flow or migration of gene can be described as a process of transfer of genetic variation from one population into another population. This process leads to change in the frequency of a gene variant ( that is called allele) in a particular population and it reduces the genetic differences between population.

If the process of gene glow is high, then the two population will be considered equivalent in genetic diversity.

Thus, Gene flow evens out genetic differences between populations
