DNA Replication Flashcards

Front

What do enzymes do?

Back

Enzymes speed up chemical reactions or allow them to occur at lower energy levels.

Front

Most enzymes end with this suffix:

Back

-ase

Front

Which enzyme starts the DNA replication process by unzipping the DNA strand?

Back

Helicase

Front

Which enzyme leaves "primers" on the DNA strand to tell another enzyme where to start building?

Back

Primase

Front

Which enzyme adds new nucleotides to build the new strand of DNA?

Back

DNA Polymerase

Front

Which enzyme can proofread replicating DNA and avoid any incorrectly inserted nitrogen bases during replication?

Back

DNA polymerase

Front

Which enzyme glues together the fragments on the lagging strand?

Back

Ligase

Front

DNA strands move in an antiparallel pattern. What does this mean?

Back

the strands move in opposite directions

Front

What is the first step in DNA replication?

Back

Helicase breaks the hydrogen bonds between the bases to split the original strand.

Front

What is the second step in DNA replication?

Back

Primase marks where to start building the new strand of DNA
