DNA Structure and Pairing Concepts

Front

What is the structure of DNA?

Back

DNA is a double helix composed of two strands of nucleotides, which include a sugar, a phosphate group, and a nitrogenous base.

Front

What are the four nitrogenous bases in DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).

Front

What is base pairing in DNA?

Back

Base pairing refers to the specific pairing of nitrogenous bases: Adenine pairs with Thymine (A-T) and Cytosine pairs with Guanine (C-G).

Front

What is the role of the active site in an enzyme?

Back

The active site is the region on an enzyme where substrate molecules bind and undergo a chemical reaction.

Front

What is a substrate in enzymatic reactions?

Back

A substrate is the reactant molecule upon which an enzyme acts.

Front

What is the enzyme-substrate complex?

Back

The enzyme-substrate complex is the temporary molecule formed when an enzyme comes into perfect contact with its substrate.

Front

What is the complementary DNA sequence for the strand AAT GGC?

Back

The complementary DNA sequence is TTA CCG.

Front

What are the products of photosynthesis?

Back

The products of photosynthesis are glucose and oxygen.

Front

What is the primary function of glucose in living organisms?

Back

Glucose molecules store chemical energy that can be used for cellular processes.

Front

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

Back

The double helix structure allows for the efficient storage of genetic information and the ability to replicate accurately.
