DNA Transcription and Translation Concepts

When DNA is isolated from a cell and stretched out, DNA looks like a

• staircase.

• sugar cube.

• twisted ladder.

• twizzler.

The name of the shape of DNA is called a

• pentagon.

• double helix.

• hexagon.

• tripple spiral.

Speaking of the structure of DNA, the sides of the DNA ladder are called the

• bar.

• rung.

• base.

• backbone.

Speaking of the structure of DNA, the rungs of the DNA ladder are made of pairs of small chemicals called

• bars.

• rungs.

• bases.

• backbones.

Which of the following are one of the chemical base pairings?

• Adenine and Guanine.

• Adenine and Thymine.

• Adenine and Cytosine.

• Thymine and Cytosine.

Which of the following are one of the chemical base pairings?

• Thymine and Guanine.

• Cytosine and Thymine.

• Cytosine and Adenine.

• Cytosine and Guanine.

DNA is made of chemical building blocks called

• nucleotides.

• bases.

• chemicals.

• phosphates.

Nucleotides are made of three parts:

• a backbone, a step and a base.

• a nitrate, a phosphate and a step,

• a phosphate group, a sugar group and one of four types of nitrogen bases.

• a twizzler, a toothpick and a marshmallow.

The complementary strand to TACG would be

• GCAT.

• tacg.

• CGAT.

• ATGC.

The backbone of DNA is made of

• a nitrogen base and a phosphate group.

• a phosphate group and a simple sugar.

• a simple sugar and a nitrogen base.

• two nitrogen bases.
