BIOXII06: MOLECULAR BASIS OF INHERITANCE

343123 The coiling of double strands in B-DNA is:

1 Right- handed
2 Parallel
3 Left -handed
4 Symmetrical
BIOXII06: MOLECULAR BASIS OF INHERITANCE

343124 Read (i) to (v) and find the correct option
i. Nitrogen base is linked to pentose sugar through N-glycosidic linkage
ii. Phosphate group is linked to 5' - \(\mathrm{OH}\) of a nucleoside through phosphoester linkage iii. Two nucleosides are linked through \(3^{\prime} \rightarrow 5^{\prime}\) N-glycosidic linkage
iv. Negatively charged DNA is wrapped around positively charged histone octamer to form nucleosome
v. Chromatin that is more densely packed and stains dark is called euchromatin

1 i alone is wrong
2 iv alone is wrong
3 iii and \(v\) are wrong
4 i, ii, iii wrong

343125 Information flow or central dogma of modern biology is

1 RNA - Proteins- DNA
2 DNA - RNA - RNA
3 RNA -DNA- Proteins
4 DNA - RNA -Proteins
