Question

1) Which one of the following would least likely be found in a cell that has entered M-phase?

Mitotic chromosomes

Nucleosomes

Heterochromatin

Histones

A nucleolus

Which of the following amino acids is likely to be the most abundant in Histone H1?

Leucine
Aspartate
Cysteine
Lysine
Phenylalanine

Nucleases:


work only in the 3' to 5' direction.
are the "beads" in the "beads on a string" form of chromatin.
supercoil DNA.
degrade nucleic acid chains.
are the "string" in the "beads on a string" form of chromatin.

Which one of the following is the most likely indicator that a cell is in interphase?

More heterochromatin than euchromatin
Most of the DNA is unfolded to 10-nm or 2-nm fibers
Presence of a nucleolus
Chromosomes are more tightly packed overall
Chromosomes are visible under light microscopy

Explanation / Answer

1)- option e is correct because nucleolus start to disappear in prophase.

2)- option d is correct because it is family of lysine rich protein.

3)- option b is correct.

4)- option d is correct because chromosomes are condensed in interphase.
