A new strain of a virus was recently discovered. The virus is a single strand, but the scientist is unsure if it is DNA or RNA. After running tests, she determines it is DNA. What would lead her to this conclusion?

• it contains uracil

• it contains adenine

• it contains thymine

• it contains cytosine

Polio is an RNA virus. It is single stranded. How would a scientist conclude it is RNA vs DNA?

• it contains thymine

• it contains adenine

• it contains guanine

In what part of DNA is genetic information located?

• hydrogen bonds

• nucleotide sequence

• sugar molecules

• enzymes

DNA serves as the ​​blueprint which contains all the information that the cell needs to function.  RNA serves as the translator between the nucleic acid language and the amino acid language in proteins.​

• True

• False

Which of the following best describes how DNA and RNA are similar?

• They both contain the nitrogen bases thymine and adenine.

• They both are formed in a double-helix structure.

• They both are composed of five different nucleotides.

• They both contain the nitrogen bases cytosine and guanine.
