DNA or deoxyribonucleic acid is the molecule in living organisms wherein the genetic code or <em>genes</em> is stored. The structural conformation of DNA in the nucleus of the cells is called <em>chromatin </em><em />and in cell division, chromatin is grouped into a certain number (46, in humans, for instance) called <em>chromosomes.
</em>DNA provides instructions for hereditary such that a part of DNA is transcribed into messenger RNA or mRNA for the genetic code to be transported outside the nucleus. The mRNA is then translated into polypeptides to form proteins that form specific functions in the human body.<em>

Answer:
Explanation:
Mitosis. Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies - or 'replicates' - its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.
To measure the diameter of a organelle with a scale line of 1 µm.
- Measure the length of the scale line on the micrograph in mm, e.g. 1 µm = 17mm.
- Measure the diameter of the organelle in millimetres, e.g. = 60mm.
- True diameter of organelle.
<h3>How do you find the actual size of an organelle?</h3>
To calculate the actual size of a magnified specimen, the equation is simply Mixed6 :
Actual = Image size (with ruler) ÷ Magnification.
Thus, this is how we can measure the size of an organelle.
