Central Dogma Pt 1

Front

What type of bond joins nitrogenous bases in DNA?

Back

Hydrogen bonds.

Front

What is the result of DNA replication?

Back

Two DNA molecules, each with one new strand and one original strand.

Front

What DNA sequence pairs with ATG TGA CAG?

Back

TAC ACT GTC.

Front

What is the complementary strand for AGCTCATA?

Back

TCGAGTAT.

Front

Which organisms contain DNA?

Back

All of the above: animals, plants, bacteria.

Front

What are the four nitrogenous bases in DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), Guanine (G).

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

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

Back

They indicate the directionality of the DNA strand, which is crucial for replication and transcription.

Front

What is the function of helicase in DNA replication?

Back

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

Front

What is the difference between leading and lagging strands during DNA replication?

Back

The leading strand is synthesized continuously, while the lagging strand is synthesized in short segments called Okazaki fragments.
