hn -RNA undergoes two additional processing. Out which, in one of them an unusual nucleotide (methyl guanosine triphosphate) is added to the 5' hnRNA. This is known as

A

Capping

B

Tailing

C

Splicing

D

Termination

Text Solution

Verified by Experts

The correct Answer is:
A
Capping is a post – transcription modification of mRNA in which methylated guanine residues are added at 5’ end of mRNA to form G – cap

Select the correct statements regarding the process of transcription in eukaryotes. (i) The strand of dsDNA which takes part in transcription process is called as coding strand. (ii) The enzyme RNA polymerase can catalyse polymerisation only in one direction i.e. , 5' rarr 3' . (iii) An unusual nucleotide methyl guanosine triphosphate is added to the 5' end of hnRNA during capping. (iv) During tailing process, adenylate residues (200-300) are added at 3' end in a template independent manner.

Assertion (A): Primary transcripts in eukaryotes are non-functional. Reason (R) Methyl guanosine triphosphate is attached to 5'-end of hnRNA.

Assertion: Primary transcripts in eukaryotes are nonfunctional. Reason: Methyl guanosine triphosphate is attached to 5' - end of hnRNA.

One mole of idea monoatomic gas at 300 K undergoes an adiabatic irrersible process due to which its interhnal energy decreases by 150 calories. If the process is carried out isobarically to obtain same work then the enthalpy change of the isobaric process is :

In addition to the normal process of oxidation of carbohydrates through glycolysis and Krebs' cycle, there is another process by which plants could oxidise carbohydrates to obtain energy. In this process, hexose sugars undergo oxidatibe degradation through 5-C sugar intermediates and hence it is known as pentose phosphate pathway (P P P). Which of the following statements is not true with regard to P P P?
