DNA Structure and Replication

Front

What is the shape of DNA?

Back

Front

If the percentage of DNA is made of 30% Thymine, what is the correct percentage of Guanine?

Back

20%

Front

What is the process in which DNA makes an exact copy of itself?

Back

Replication

Front

What role does DNA replication serve in the cell cycle?

Back

Replicating DNA allows daughter cells to be produced with the same number of chromosomes after cell division.

Front

If a strand reads: 3' A A A T T T C 5', what would the matching strand read?

Back

5' T T T A A A G 3'

Front

What are the building blocks of DNA?

Back

Nucleotides

Front

What are the four nitrogenous bases in DNA?

Back

Adenine, Thymine, Cytosine, Guanine

Front

What type of bond holds the two strands of DNA together?

Back

Hydrogen bonds

Front

What is the function 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 important for replication and transcription.
