The component of the cell that determines paternity resides in the…

A. centrosome

B. ribosome

C. nucleus

D. mitochondria

QUICK ANSWER…

C

DETAILS…  

The component of the cell that determines paternity resides in the DNA which is located in a cell organelle called the nucleus.

The determination of the paternity of an organism can be done by the analysis of DNA molecules which can be found in its cell nucleus. The DNA is often seen as the hereditary material found in the Nucleus.

Now for the right answer to the above question:

  1. DNA not found in the centrosome. So, A is incorrect.
  2. DNA not found in the ribosome. B is also incorrect.
  3. DNA, especially the hereditary n-DNA is found in the nucleus. So, C is correct.
  4. D is incorrect; although the mitochondria contains a small amount of DNA called mtDNA, they are concerned with energy synthesis and not paternity.

KEY-POINTS…

You may please note that:

  • The nucleus is the major container of DNA which could determine paternity.
  • Mitochondria and chloroplast are other organelles that contain small amounts of mtDNA and cpDNA respectively, but these does not determine paternity.
