DNA & Replication

Front

What component of DNA specifies the traits of an organism?

Back

Nitrogenous base pairs are the components of DNA that specify the traits of an organism.

Front

What enzyme synthesizes short RNA sequences to guide DNA Polymerase?

Back

DNA Primase synthesizes short RNA sequences to guide DNA Polymerase during DNA replication.

Front

What is the function of helicase in DNA replication?

Back

Helicase is the enzyme that unzips the DNA double helix to prepare for replication.

Front

What type of bonds hold the two strands of DNA together?

Back

Weak hydrogen bonds between the nitrogenous bases hold the two strands of DNA together.

Front

What is the order of replication in DNA synthesis?

Back

The order of replication is: 3, 4, 1, 2.

Front

What are the four nitrogenous bases found in DNA?

Back

The four nitrogenous bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).

Front

What is the role of DNA Polymerase in DNA replication?

Back

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

Front

What is the structure of DNA?

Back

DNA has a double helix structure, consisting of two strands that wind around each other, with a sugar-phosphate backbone and nitrogenous bases in the center.

Front

What is the significance of the 5' and 3' ends of a DNA strand?

Back

The 5' and 3' ends of a DNA strand indicate the directionality of the strand, which is crucial for DNA replication and transcription.

Front

What is the function of RNA primers in DNA replication?

Back

RNA primers provide a starting point for DNA Polymerase to begin synthesizing the new DNA strand.
