Multiple choice

Cell division is, where a parent cell is divided into 2 or more daughter cells. Typically, cell division occurs as part of larger cell cycle. In eukaryotes, it is of 2 types: vegetative (daughter cell is similar to parent cell) & reductive (chromosome number in daughter cell is decreased by half for producing haploid gametes) cell division. Prokaryotes also possess vegetative cell division termed as binary fission.

The mitosis promoting factor (MPF) that propels the animal cell into division stage has 2 important sun units: 1 is catalytic & other is regulatory. Which of following is regulatory sub unit of MPF?

  1. Ubiquitin

  2. Cyclin

  3. Cdk (Cyclin dependent kinase)

  4. Proline

C Correct answer
Explanation

The mitosis promoting factor (MPF) that propels the animal cell into division stage has 2 important sun units: 1 is catalytic & other is regulatory. Cdk (Cyclin dependent kinase) is a protein kinase family which regulates cell cycle. It also regulates transcription, processing of mRNA & differentiation of nerve cells.
