DNA Replication Flashcard

Front

What is the role of DNA Ligase in DNA replication?

Back

DNA Ligase is the enzyme that connects the DNA fragments on the lagging strand, effectively 'gluing' them together.

Front

What is the first step in DNA replication?

Back

The first step in DNA replication is when DNA Helicase unwinds the original DNA strand.

Front

What is the third step in DNA replication?

Back

The third step in DNA replication is when DNA polymerase builds new strands by bringing in new nucleotide bases.

Front

What is the significance of semi-conservative replication?

Back

In semi-conservative replication, each new DNA molecule consists of one old strand and one new strand, ensuring genetic continuity.

Front

What nucleotide pairs with Adenine in DNA?

Back

Thymine pairs with Adenine in DNA.

Front

What is the function of RNA Primase in DNA replication?

Back

RNA Primase lays down an RNA primer that provides a starting point for DNA polymerase to begin synthesis.

Front

What is the role of DNA Helicase?

Back

DNA Helicase unwinds the double helix structure of the DNA, separating the two strands.

Front

What happens during the elongation phase of DNA replication?

Back

During elongation, DNA polymerase adds new nucleotide bases to the growing DNA strand.

Front

What is the function of DNA Polymerase?

Back

DNA Polymerase is the enzyme responsible for synthesizing new DNA strands by adding nucleotides complementary to the template strand.

Front

What is the lagging strand in DNA replication?

Back

The lagging strand is the strand that is synthesized discontinuously in short segments called Okazaki fragments.
