The _______________ pathway of RNA interference is a result of double stranded DNA entering a eukaryotic cell.

Biology
1 answer:
Anit [1.1K]2 years ago

Answer:

siRNA.

Explanation:

The RNA interference may be defined as the evolutionary conserved mechanism that helps in the gene regulation by the silencing of the small RNA molecules. Two main types are  siRNA and miRNA.

The siRNA (small interference RNA) is involved in the protection of the cell by destroying the exogenous ds DNA of the cell. The DICER  enzyme plays an important role in the processing of the small interference RNA and the guide strand of RNA is involved in the gene silencing.

Thus, the answer is option (a).

In humans, the DMD gene is required for proper muscle function. Mutations in the DMD gene display X-linked recessive inheritance
ANEK [815]

Answer:

Explanation:

As the inheritance is X-linked,recesson so for expression of muscular dystrophy in any given muscle,

\frac{enh1-    enh2+   enh3 -   DMD+ }{enh1-    enh2+   enh3 +   DMD+}

enh1+ /enh1 + = Shows muscular dystrophy in heart (Homozygous for -)

enh2+/enh2+ = Shows no muscular dystrophy in arms (Homozygous for +)

enh3-/enh3+ = variabl or mosaic for muscular dystrophy in leg muscles (Hetrozygous for enh3)

To which substance does ferredoxin transfer an electron?
Sonbull [250]

The right answer is NADP+.

Ferredoxin is an iron-sulfur protein that effects electron transfer in a large number of redox reactions in cell metabolism through Fe-S clusters whose iron cations oscillate between +2 (ferrous) oxidation states. and +3 (ferric). The first protein of this type was isolated in 1962 from the anaerobic bacterium Clostridium pasteurianum. A chloroplast-specific ferredoxin is involved in the cyclic and noncyclic photophosphorylation reactions of photosynthesis. In non-cyclic photophosphorylation, ferredoxin is the ultimate electron acceptor and reduces NADP + under the action of ferredoxin-NADP + reductase (EC 1.18.1.2) with FAD and a flavin group as cofactors:

2 ferredoxin- [Fe (2+) Fe (3+) S2 (-2)] + NADP (+) + H (+) ==> 2 ferredoxin- [Fe3 (+2) S2 (-2)] + NADPH .

1. Parasites

2. herbivores

3. phagocytosis

4. Plant

5. oxygen (O2)

6. gills

7. open

8. urea

9. Single-loop circulatory systems have one direction of blood flow. Typically in fish, oxygen is absorbed in the gills, flows in blood to the body organs, and back to the heart, which pumps it directly back to the gills. In double-loop circulatory systems, the heart has multiples of each chamber. Part of the heart pumps blood to the lungs, to get oxygen. This blood flows back to a different chamber where it then gets pumped to the body. Once its oxygen has been used up, it goes back to the heart to be pumped all over again to the lungs.

10. Freshwater animals have lower water and higher salt concentrations than the environment in their cells. This means water constantly tries to diffuse into the animals, which can bloat them. They have special cell processes that remove extra water.
