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.
