What helix shaped structure tells the cell when to grow and what to do?

Answer:

Deoxyribo Nucleic Acid (DNA) is a helix-shaped structure that tells the cell when to grow and what to do.  

Explanation:

DNA is made up of polynucleotide sequences that code for the information of the synthesis of the particular protein.

These proteins further help the host cells of different organs and tissues to carry out different functions like cell growth, cell division and cell-cell communication. Defects in DNA sequence can also leads to uncontrolled cell division and cell growth leading to tumor formation.
