Question

groups of specialized cells form body tissues. tissue function is carried out by the proteins that are produced by specialized cells. what is true about specialized cells?
a. the sequence of genes in the dna of specialized cells never determines how the cell functions.
b. specialized cell function is independent of the structure of the proteins produced by the cell.
c. the structure of the proteins produced by specialized cells is independent of the sequence of genes in the cells dna.
d. specialized cell function is largely determined by the structure of the proteins that the cell produces.

Explanation:

• Option A: The sequence of genes in DNA determines cell functions. So this option is wrong.
• Option B: Specialized cell function depends on the proteins produced by the cell. So this option is wrong.
• Option C: The structure of proteins is determined by the gene sequence. So this option is wrong.
• Option D: Cell function is largely determined by the proteins it produces. This is correct as proteins carry out most of the functions in a cell.

Answer:

D. Specialized cell function is largely determined by the structure of the proteins that the cell produces.
