Question

How many following statements are correct?
(A) Nucleus as a cell organelle was first described by Robert Brown as early as 1651.
(B) The interphase nucleus has highly condensed nucleoprotein fibres called chromatin.
(C) During different stages of cell division, cells show structured chromatin in place of the nucleus.
(D) Every chromosome essentially has a primary constriction which is also known as NOR.
(E) Many membrane-bound minute vesicles called microbodies that contain various enzymes are present in both plant and animal cells.

• A. One
• B. Two
• C. Three
• D. Four

Answer 1

Answer: (B)

Two

Answer is option B i.e. "Two"

• Correct statements are statements C and E because-
  

During cell division stages of eukaryotes instead of nucleus, DNA associated with histone proteins in a highly condensed nucleoprotein complex is called chromatin.
Microbodies are membrane-bound minute vesicular organelles. They are found in both plant and animal cells. They contain various enzymes and proteins.

• While, Nucleus was discovered by Robert Brown in 1831 and published in 1833.

• During interphase chromatin is distributed throughout the nucleus.
• Every chromosome essentially has a primary constriction which is also known as kinetochores. Nucleolus organiser regions (NORs) are chromosomal regions crucial for the formation of the nucleolus.
