Answer:
It is required that the seed region of the processed dsRNA molecule bind to the mRNA of mex-3 in order to inhibit its translation
Explanation:
Double-stranded RNAs are small interfering non-coding RNAs (about 20 nucleotides in length) that, after processing, can bind by complementary base pairing to RNAs and thus inhibit protein translation by a mechanism referred to as 'RNA interference' (RNAi). The base pairing is not always perfect; however, the guide strands of dsRNAs can conserve their ability to inhibit the translation if the complementarity is enough good to match target RNA sequences. The critical region in the dsRNA that is required to bind target RNAs is known as seed region, and consists of 6 to 8 nucleotides in length.
Nitrogen Fixation- Special bacteria convert the nitrogen gas (N2 ) to ammonia (NH3) which the plants can use. Step 2- Nitrification- Nitrification is the process which converts the ammonia into nitrite ions which the plants can take in as nutrients.
From what I remember from my bio class, the answer should be True. Hope this helps :)
It's an adaption of the Southern blot procedure, used to identify specific amino - acid sequences in proteins.
Answer:
The genes are linked and 10 mu apart.
Explanation:
A female AaBb rabbit is test crossed with a male rabbit (aabb). The male can only produce<em> ab</em> gametes (all the progeny will have ab on one of the homologous chromosomes).
If the genes assorted independently, the female would produce 4 types of gametes with the same frequency: 1/4 AB, 1/4 Ab, 1/4 aB and 1/4 ab.
However, the observed AB and ab gametes were much more frequent than Ab and aB, which means that the genes are linked and alleles on the same chromosome do not assort independently during meiosis.
Recombination is a rare event, so the most abundant gametes are the parentals. That is how we know that the mother had the AB/ab genotype. The recombinant gametes therefore are Ab and aB.
Distance (mu) = # Recombinants × 100/ Total progeny
Distance = (54 + 46) × 100/ 1000
Distance = 100 × 100/1000
Distance = 10 mu
