DNA Structure and Function Concepts

Front

What is the primary function of DNA in living organisms?

Back

To store and transmit genetic information for building and maintaining an organism.

Front

Which three components make up a nucleotide, the building block of DNA?

Back

Sugar, phosphate group, and nitrogenous base.

Front

In a healthy strand of DNA, which nucleotide bases always pair together?

Back

Adenine with Thymine, Guanine with Cytosine.

Front

What is the role of the enzyme helicase during DNA replication?

Back

To break hydrogen bonds and separate the two strands of DNA.

Front

What is the outcome of DNA replication?

Back

Two identical DNA molecules, each with one original and one newly synthesized strand.

Front

What is the primary function of the enzyme Helicase during DNA replication?

Back

To create a replication bubble by unwinding the DNA double helix.

Front

How does DNA Polymerase synthesize the lagging strand during DNA replication?

Back

It adds bases in short fragments, moving away from the replication fork.

Front

Which statement accurately describes mutations?

Back

Mutations are changes in the genetic code that can be neutral, harmful, or beneficial.
