The trenbolone acetate caused frank's testicles to shrink<span> because the steroid is taking over
the job of the testes so the testes don’t have to do as much work making them
less muscular. Trenbolone acts in the same way
that testosterone acts, but the esterified form of the hormone is approximately
3 times more potent than the naturally occurring hormone; that is, 3 times more
testosterone is required to produce the same effects as a particular amount of
trenbolone acetate. </span>Some of
its trade names are Trenbol, ester derivative and synthetic steroid. Its chemical structure is similar
to that of testosterone, the naturally occurring hormone that is produced by
the testicles.
Answer:
Basically the translation of CK-B protein is inhibited in the U937D cells, despite the fact that the CK-B protein is bounded to the ribosomes. This is because(<u>mechanisms)</u> the translation is inhibited by the binding of translational repressors to the 3’UTR of the CK-B mRNA rather than the actual CK-B mRNA 3'UTR.
Furthermore, the soluble protein inhibitions is due to the reaction of the U937 cells to the short RNA sequences with the 3’UTR.
<u>The introduction of these sequences(shot segement of RNA) </u>into the U937D cells leads to CK-B synthesis. This makes 3’UTR sequences to bind to the translational repressor proteins, thus preventing them from binding to the CK-B mRNA
.
COMPLETED QUE.
A common feature of many eukaryotic mRNAS is the presence of a rather long 3' UTR, which often contains consensus sequences. Creatine kinase B (CK-B) is an enzyme important in cellular metabolism. Certain cells—termed U937D cells—have lots of CK-B mRNA, but no CK- B enzyme is present. In these cells the 5’ end of the CK-B mRNA is bound to ribosomes, the mRNA is apparently not translated. Something inhibits the translation of the CK-B mRNA in these cells. Researchers introduced numerous short segments of RNA containing only 3’UTR sequences into U937D cells. As result, the U937D cells began to synthesize the CK-B enzyme, but the total amount of CK-B mRNA did not increase. The introduction of short segments of other RNA sequences did not stimulate the synthesis of CK-B; only the 3’UTR sequences turned on the translation of the enzyme. Based on these results, <u>purpose a mechanism for how CK-B translation is inhibited in U937D cells. Explain how the introduction of short segments of RNA containing the 3'UTR sequences might remove the inhibition.</u>

Hello there ^ _ ^
The portion of the DNA molecule that is translated is composed of anticodens.
Good luck!
Answer:
The box will not move because balanced forces are acting on it.
Explanation:
According to Newton's first law of motion, an object will remain in its state of rest or motion along a straight line unless acted upon by an unbalanced force.
An unbalanced force is an individual force acting on any side of an object which is not balanced by a force of equal magnitude acting in the opposite direction.
From the image, two forces of equal magnitude of 10 N are pulling the 100 kg box in opposite directions. Since the two forces, 10 N each are pulling the object in opposite directions, they are balanced forces. Therefore, the box will not move because balanced forces are acting on it.
