DNA Structure

DNA is made up of two strands of nucleotides held together by hydrogen bonds between complementary bases.

DNA Replication

The process by which DNA copies itself to create an identical copy.

DNA Strand Separation

The separation of the two DNA strands during replication.

DNA Polymerase

An enzyme essential for DNA replication, it binds to the single-stranded DNA and adds nucleotides to the new strand.
