Chromosomes first become visible during prophase.
Cell lysis is used to break open cells to avoid shear forces that would denature or degrade sensitive proteins and DNA. Cell lysis is used in western and Southern blotting to analyze specific proteins, lipids, nucleic acids, reporter assays, immunoassays, and protein purification. Hope this helps:)

Answer:
The correct option is C. Color blindness is an example of sex-linked traits.
Explanation:
Sex-linked traits can be described as those traits for which genes are present on the sex chromosomes. In humans, as X chromosome is a lot bigger than the Y chromosome, hence majority of the sex-linked traits are present on the X chromosome.
Colour blindness is an X linked trait and is more common to men than to women. This is because the gene for colour blindness is present on the X chromosome. As men have only one X chromosome so they have more chances of this disease.
