Answer:
The correct answer is that the spliceosome is non-functional.
Explanation:
A spliceosome refers to a composite and large molecular apparatus found mainly inside the nucleus of the eukaryotic cells. The prime function of the spliceosome is to remove the introns from a transcribed pre-mRNA, that is, a kind of primary transcript.
In case if the spliceosome machinery gets failed to function, the mRNA will not remove the introns, that is, the non-coding parts and retains it. This will eventually lead to the formation of longer mRNAs.
Answer:to stop from extinction
Explanation:
Answer:
C) Three hydrogen bonds will form with guanine.
Explanation:
Generally the DNA molecule is made up of Purines bases of Adenine and Guanine,and Pyrimidine of Cytosine and Guanine.However,RNA contains a different pyrimidine of Uracil.Thus the pairing is A-U am C-G.The uracil replaces Thymine.
The structure above is a Pyrimidine,because it is made up of single ring structure(an heterocylclic aromatic structure) compare to double structure of purines. Heterocyclic means it is ring form.Aromatic means it has resonance bonds which shift with the rings for stability.
It is also contains of two substitutes at position 4 of the ring structure (amineNH2) and at 2 which is the Keto group(=0).Therefore the structure is Cytosine.
In RNA structure the Cytosine pair with the three hydrogen bonds with guanine,while Adenine pair with Uracil.This ensures stability of the RNA structure.
Both the plants and fungi possess the tendency to absorb nutrients from the soil. Plants do that with the help of roots and fungi does that with the help of hyphae.
Both the plants and fungi possess cell walls in the form of cellulose and chitin. However, only some of the plants possess the tendency to have rhizomes like ginger, lotus, turmeric, and several kinds of ferns.
Plants are mostly autotrophs, however, certain plants like insectivorous plants depend on others for their source of nutrition, that is, and insectivorous plants are heterotrophic. On the other hand, all the fungi show the heterotrophic mode of nutrition.
Only plants possess the tendency to perform the process of photosynthesis. In fungi, due to the absence of green pigment, that is, chlorophyll, they do not possess the tendency to perform photosynthesis.
Only fungi exhibit aseptate hyphae, these structures perform various functions in fungi. They comprise the cell sap or cytoplasm, also the nuclei comprising the genetic substance. It also helps in the absorption of nutrients from the surroundings.
Mainly the seeds are produced by plants and fungi produces spores.
