DNA Structure, Replication, Mitosis, Cell Differentiation

Front

What is the structure of DNA?

Back

DNA is structured as a double helix, consisting of two strands that wind around each other.

Front

What are the building blocks of DNA?

Back

The building blocks of DNA are nucleotides, which are composed of a phosphate group, a sugar (deoxyribose), and a nitrogenous base.

Front

What base pairs with Adenine in DNA?

Back

Thymine pairs with Adenine in DNA.

Front

What is the process of copying DNA before cell division called?

Back

The process of copying DNA before cell division is called DNA replication.

Front

What are the two main functions of DNA?

Back

The two main functions of DNA are to store genetic information and to provide instructions for protein synthesis.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells.

Front

What is the role of the phosphate group in a nucleotide?

Back

The phosphate group helps form the backbone of the DNA strand and connects to the sugar of the next nucleotide.

Front

What is cell differentiation?

Back

Cell differentiation is the process by which a less specialized cell becomes a more specialized cell type.

Front

What is the significance of the double helix structure of DNA?

Back

The double helix structure allows for the stable storage of genetic information and the accurate replication of DNA.

Front

What is the difference between DNA and RNA?

Back

DNA contains deoxyribose sugar and thymine, while RNA contains ribose sugar and uracil.
