Correct option-(c) Polytene chromosomes develop from the chromosomes of diploid nuclei by successive duplication of each chromatid without their separation, as such, each chromosome has several strands of DNA. Here they are talking about the WT alleles being recessive. ALso if the initial...

Hi. I have been recently introduced to a website called targetscan which is both a database and a tool to discover recorded miRNA-target gene interactions. I'm stuck with some questions. For TargetScanMouse, when Hmga2 gene is used as the query/input, a number of miRNAs come out. If I choose...

I actually needed the simplest, or more precisely the shortest method to answer this question, as I was preparing for a MCQ-based exam. Thank you everyone for your pointers and inputs. Thank you Delta2. :)

The other side can be between, (7+3=)10 and (7-3=)4 cm, being an isosceles triangle, the third side should be either 7 or 3. As 3 is below the range so 7cm is the length of the other side. Thanks for the pointer.

Where did I go wrong?

Thank you so much. I got it. Your pointer really helped.

Considering the general Michaelis-Menten curve, in the region where S < Km, the V0- relationship is linear, so yes the reaction velocity doubles as S approximately doubles. It is not the same when S > Km, because the slope decreases, the rise of V0 with S will be less than double.

Using the formula V1S1=V2S2, I have found the volumes of stock solutions needed to make Tris-EDTA of the STE buffer. VTris=100ml and VEDTA=50ml. How to find out volume of sucrose ?

The relevant formua: V0= (Vmax x )/ (Km + ) From the question: 2(Vmax x 0.5)/ (Km + 0.5) = (Vmax x 1)/ (Km + 1) => 2(Vmax x 0.5)/ (Km + 0.5) = (Vmax x 1)/ (Km + 1) => 1 x (Km +1) = (Km + 0.5) Where am I making the mistake?

Source: paper When the cells were transfected with miRNA-mimic it increased the miRNA expression. Is this increase due to the activity of RNA-dependent RNA polymerase, which generates secondary miRNAs?

I think it is asking which out of the three can oxidize BH2. In that case, I think (b) is the correct option. Thanks for pointing out, I got confused after reading the question. I really is unclear. But if they are asking for the oxidant, shouldn't Y element be excluded?

😊 Thanks

Where have I gone wrong? According to the key, the right option is a.

The answer key says the correct option should be a, but I think it should be b. Because Y has a reduction potential same as the element B. An element is a good reducing agent only if its reduction potential is negative or less positive.

Thank you everyone for responding to this thread. @Ygggdrasil Thank you, for such a big help! I didn't think I could really find a scientific paper on top prescribed drugs and was mostly Googling. @DaveC426913 Thanks for sharing that you are on Dulaglutide. I thought Sulfonylurea and...
