The signal transduction pathway allows the signal transduction pathway allows a cell to repair damage to its dna one cell to regulate the gene expression of another cell whole genomes to be sequenced genes from one organism to be inserted into the nucleus of another organism's cells

The correct answer will be option-one cell to regulate the gene expression of another cell

Explanation:

Signal transduction is the cascade of reactions taking place in the cell in response to a ligand or inducer. The signal transduction takes place at the molecular level in the cell but it shows its effect at a greater level.

There are many pathways of signal transduction but the main aim of the pathways is to regulate the functions of the cell through gene expressions.

The regulation of the gene expression of one cell by another cell is one of the ways of the signal transduction pathway like in apoptosis.

Thus, option-one cell to regulate the gene expression of another cell is the correct answer.

eukarya because is is like alche and b is bacteria and d is animals

explanation:

the backbone of the dna and rna compound is sugar phosphate.
