Which part of chromatin is transciptionally inactive and active respectively?
1 Heterochromatin and Euchromatin
2 Nucleosome and Euchromatin
3 Euchromatin and heterochromatin
4 Chromosome and Euchromatin
Explanation:
Euchromatin is said to be transcriptionally active chromatin, whereas heterochromatin is inactive.

Which one of the following statements about the particular entity is true?
1 Centromere is found in animal cells, which produces aster during cell division.
2 Nucleosome is formed of nucleotides
3 The gene for producing insulin is present in every body cell.
4 DNA consists of core of eight histones.
Explanation:
The insulin producing gene is found in occurs in every body cell but it is not indicated in all cells. A nucleosome consists of a segment of DNA containing eight histone protein cores. A centromere found in chromosomes is a region of DNA where two chromatids are attached. While aster is produced by centriole (found in animal cells) during cell division.
