UNIT 4 concept 1 flashcard

Front

What is the structure of DNA?

Back

Double helix.

Front

Which compound is identified as DNA based on specific characteristics?

Back

Compound C.

Front

What is the semi-conservative model of DNA replication?

Back

The end result of DNA replication is 2 identical DNA strands that are 1/2 old and 1/2 new, thus it is semi-conservative because half of the original DNA is conserved.

Front

What is the complementary strand for the DNA sequence G C A T T A C G G T A A?

Back

C G T A A T G C C A T T.

Front

What is the structure of RNA?

Back

Single strand.

Front

Define DNA.

Back

DNA (Deoxyribonucleic Acid) is the molecule that carries the genetic instructions for life.

Front

What are the building blocks of DNA?

Back

Nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.

Front

Name the four nitrogenous bases in DNA.

Back

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

Front

What base pairs with Adenine in DNA?

Back

Thymine (T).

Front

What is the function of DNA?

Back

To store and transmit genetic information.
