Two different cells taken from the same human were viewed using a microscope - VCE - SSCE Biology - Question 11 - 2019 - Paper 1

The correct conclusion to reach when comparing the two cells is:

A. At any given time, the genes expressed in each cell may be different.

This statement is accurate because different cells can express different sets of genes depending on their functions and the physiological conditions they are in. For example, neutrophils are involved in immune responses while neurons are involved in signal transmission and processing in the nervous system.

B. All proteins in each cell will have similar tertiary structures.

This is incorrect, as different cell types typically produce different proteins which can have varied tertiary structures.

C. The two cells have the same proteome.

This is also incorrect, as the proteome of a cell can vary significantly based on the cell type and its functions.

D. The two cells have different genomes.

This statement is misleading; while the genomes will be the same as they come from the same individual, the expression of the genes can lead to different phenotypes.
