BIOXII06: MOLECULAR BASIS OF INHERITANCE
342901
Nucleosome contains:
1 Both DNA and histone protein
2 Only DNA
3 Only histone protein
4 Both DNA and RNA
Explanation:
The nucleosome contains 146 DNA base pairs wrapped in super helical turns around a histone octamer that consists of 2 copies each of the core histones H2A, H2B, \(\mathrm{H} 3\), and \(\mathrm{H} 4\) and linker DNA contain 54, total \(200 \mathrm{Npb}\) in some Nucleosome

The DNA in nucleoid is organised in
1 Large loops held by histones
2 Large loops held by nucleotides
3 Large loops held by sugar
4 Large loops held by proteins
Explanation:
The DNA in nucleoid is organised in large loops held by proteins

Find the correct statement with respect to structure of Euchromatin?
1 Loosely packed, Stain light
2 Loosely packed, Stain dark
3 Densely packed, Stain light
4 Densely packed, Stain dark
Explanation:
In a typical nucleus, some region of chromatin are loosely packed (and stains light) and are referred to as euchromatin.

342904
Assertion : Euchromatin is said to be transcriptionally active. Reason : Because it is more densely packed and stains dark.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
Explanation:
Euchromatin is said to be transcriptionally active, because it is loosely condensed and accessible by RNA polymerase. More densely packed and stains darkly is Heterochromatin.
