DNA Structure

What is the role of the sugar in a nucleotide?

• It forms the backbone of the DNA structure.

• It acts as a catalyst for DNA replication.

• It provides energy for cellular processes.

• It helps in the formation of proteins.

How does DNA control the functions of a cell?

• By directing the synthesis of proteins that perform various functions.

• By regulating the cell's energy production.

• By controlling the cell's shape and structure.

• By determining the cell's lifespan.
