Front

This enzyme unwinds and unzips the DNA molecule by breaking apart hydrogen bonds which holds the complementary nitrogenous bases together.

Back

helicase

Front

Back

continuous; discontinuous

Front

DNA is always synthesized in which direction?

Back

Back

True

Front

What type of bond is formed between base pairs in order to hold the two DNA strands together which form a double helix?

Back

Hydrogen bond

Front

The ligase enzyme seals gaps between DNA fragments and is similar to "molecular glue", binding different pieces of DNA together to form new sequences.

Back

True

Front
