There are 27 x 10⁷ cells in total for the given conditions of cell culture.
Since it is given that the cell culture contains 3 x 10⁵ cells per ml and there are 12 culture flasks in total. It is also given that each of the culture flask holds 75 ml of culture.
Therefore, to calculate the total capacity of the flasks the total number of flasks should be multiplied with the individual capacity of a flask:-
75 x 12 = 900 ml
Now, in order to calculate the total number of cells in the given culture., the total capacity of the flasks i.e. 900 ml should be multiplied with 3 x 10⁵ cells per ml in the following manner:-
900 x (3 x 10⁵) = 2700 x 10⁵ = 27 x 10⁷ cells

<u>Answer:</u>
<em>Polymers of amino acids can be both fibrous as well as globular protein. Hemoglobin is a globular but the collagen is the fibrous protein both being the amino acids.</em>
<u>Explanation:</u>
- <em>Soluble in water: </em>globular protein is soluble in water.
- <em>intermediate filaments:</em> fibrous protein
- <em>Insoluble in water:</em> fibrous protein is insoluble in water.
- <em>function as structural proteins in the cell:</em> fibrous protein.
- <em>some function as enzymes: </em>globular protein.
- <em>structure is somewhat spherical;</em> globular protein.
- <em>structure is rod-like:</em> fibrous protein
Once the DNA of a person has been copied it can be compared to the DNA of other people by using PCR (Polymerase Chain Reaction).
