DNA Test Review Quizziz

The two strands of DNA are held together by:

• Hydrogen Bonds
• Phosphodiester Bonds
• Glycolsyl Bonds
• Glycosidic Linkages

In a molecule of double-stranded DNA, the amount of Adenine present is always equal to the amount of

• cytosine
• guanine
• thymine
• uracil

What determines the code, or information, of a DNA molecule?

• the shape (structure) of the nitrogen bases
• the order (sequence) of the nitrogen bases
• the color of the nitrogen bases
• the frequency (number) of nitrogen bases

A process in which DNA has the unique ability to make an exact copy of itself.

• Replication
• Translation
• Transcription

Replicate the following strand of DNA: 
AATCATGGA

• AATCATGGA
• TTAGTACCT
• UUAGUACCU
• GGATAUCUA

DNA replication results in two DNA molecules,

• each one with two original strands
• each one with two new strands
• each one with one new strand and one original strand
• one with two new strands and the other with two original strands

RNA contains the sugar

• ribose
• deoxyribose
• glucose
• lactose
