1)DNA codes for proteins that determine eye color.
2)DNA codes for mRSA that determines eye color.
3)DNA interacts with proteins to control eye color.
4) DNA contains pigments which make up eye color.

Thanks conexus student!

I think you misstyped 2) Should it be mRNA?

yes I did , mRNA .

That ought to give you a clue.

conexus student is right

That's correct! DNA codes for proteins that determine eye color.

To explain the process further, the DNA molecule is made up of genes, which are sections of DNA that provide the instructions for making specific proteins. In the case of eye color, there are specific genes that provide instructions for the production of proteins responsible for the pigmentation of the iris, the colored part of the eye.

These proteins, such as melanin, determine the amount and type of pigment present in the iris. The more melanin produced, the darker the eye color will be, while less melanin results in lighter eye colors. The specific combination of genes inherited from both parents influences the expression of these proteins, ultimately determining an individual's eye color.

So, in summary, the DNA contains genes that code for proteins, and these proteins are responsible for determining eye color by controlling the pigmentation of the iris.
