What is the first step of DNA replication?

Back

DNA Helicase unwinds the original DNA strand.

Front

What is the second step of DNA replication?

Back

RNA Primase lays down RNA primer for new nucleotide bases.

Front

What is the third step of DNA replication?

Back

DNA polymerase builds new strands by bringing in new nucleotide bases.

Front

What is the fourth step of DNA replication?

Back

Ligase knits together fragments on the lagging strand.

Front

What does 'semi-conservative' mean in the context of DNA replication?

Back

It means that during DNA replication, one original strand is reused to create a new strand.

Front

What is the directionality of DNA strands?

Back

DNA strands are said to be anti-parallel, meaning they run in opposite directions.

Front

What role does DNA Helicase play in DNA replication?

Back

DNA Helicase unwinds the original DNA strand to allow replication to occur.

Front

What is the function of RNA Primase in DNA replication?

Back

RNA Primase lays down an RNA primer to initiate the synthesis of new DNA strands.

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase builds new DNA strands by adding nucleotide bases complementary to the template strand.

Front

What is the function of Ligase in DNA replication?

Back

Ligase connects and knits together the Okazaki fragments on the lagging strand.
