Scientists claim that DNA is a universal genetic code that is common to all organisms. Which of the following statements supports this claim?

• DNA is made of proteins that can be transferred from prokaryotes to eukaryotes.
• All living things pass down their genetic code to their offspring.
• All living things use the same 4 nitrogen bases to code for traits.
• DNA is helical in structure and can be found in the nucleus.

A segment of DNA is represented in the illustration. How is information for a specific protein carried on the DNA molecule?

• As a sequence of nucleotides
• In the double-helix shape of the condensed chromosome
• In the ratio of adenines to thymines
• As a pattern of phosphates and sugars

Which part of the nucleotide codes for our traits?

• phosphate

• sugar

• nitrogen base

When G pairs with C, we call these:

• complimentary

• binary

• grouped

The result of DNA replication is

• two identical strands of DNA

• two identical daughter cells

• four strands of different DNA

• two different daughter cells

In each new DNA molecule, one strand is "old" and one strand is "new". This type of replication is called:

• semi constant

• semi replicable

• semi conservative
