What bond holds the two DNA strands together?

Back

Hydrogen bonds hold the two DNA strands together, allowing them to form the double helix structure.

Front

What is the shape of a DNA molecule?

Back

The shape of a DNA molecule is a double helix, resembling a twisted ladder.

Front

What is the name of the process by which DNA is copied?

Back

The process by which DNA is copied is called replication.

Front

Back

The complimentary strand is TGA CCG ATG TTA GTC.

Front

Where would you find DNA/chromosomes within a cell?

Back

DNA/chromosomes are found within the nucleus of a cell.

Front

What are the building blocks of DNA?

Back

The building blocks of DNA are nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.

Front

Name the four nitrogenous bases in DNA.

Back

The four nitrogenous bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase is an enzyme that synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

What is the difference between leading and lagging strands during DNA replication?

Back

The leading strand is synthesized continuously in the direction of the replication fork, while the lagging strand is synthesized in short segments (Okazaki fragments) away from the fork.

Front

What is the function of helicase in DNA replication?

Back

Helicase is an enzyme that unwinds and separates the two strands of the DNA double helix during replication.
