Centre of DNA Fingerprinting and Diagnostics (CDFD) is located at Hyderabad.
In a bacterium, the amount of adenine was found to be 18 per cent. Suggest the cytosine base composition from the following
According to Chargaff’s rule,
(A + T) + (G + C) = 100%
(A = T) + (G = C) = 100%
(18% + 18%) + 2G = 100%
36% + 2G = 100%
2G = 100% – 36%
G = 32%
In which of the following combinations, the compounds in ascending order based on their molecular weights are arranged?
The arrangement of compounds in ascending order according to their molecular weight is AMP, ADP, ATP, RNA, DNA
If a segment of an mRNA molecule has the sequence 5’ GUACCGAUCG 3’, which of the following could have been the template DNA molecule?
The correct answer is 3' CATGGCTAGC 5'
hn-RNA undergoes two additional processing. Out of which, in one of them an unusual nucleotide (methyl guanosine triphosphate) is added to the 5’-end of hnRNA. This is known as
Heterogeneous nuclear RNA (hnRNA) undergo two additional processing known as capping and tailing. In Capping an unusual nucleotide (methyl guanosinetriphosphate) is added to the 5’ end of hnRNA. In tailing, a adenlate residues (200-300) are added at 3’ end in template independent manner. In splicing, intorns are removed and exons are joined in a definite order.
The technique of DNA fingerprinting involves the following events in the order
1isolation of DNA
2-DNA digestion by Restriction Endonuclease
3-DNA separation
4-Southern blotting
(5)Hybridisation
(6)Autoradiography
