DNA & RNA
What does DNA stand for?
Deoxyribonucleic acid
Where is DNA primarily found?
The nucleus
The base of adenine bonds to what?
Thymine
Three subunit molecules in which a pentose sugar is bonded to a phosphate group and a nitrogen base
A nucleotide
DNA's primary function.
To store and transfer genetic information
RNA contains this pentose sugar.
Ribose
What kind of bonds hold together base pairs?
Hydrogen bonds
Name the four nitrogenous bases found in RNA
A, G, C, U
Adenine, Guanine, Cytosine, Uracil
Primary function of RNA.
To synthesize proteins
DNA contains this pentose sugar.
Deoxyribose
What is the enzyme that unwinds the DNA double helix?
DNA helicase
Name all 3 units found in a nucleotide
Nitrogenous base, phosphate group, and a sugar (pentose).
One key difference between RNA and DNA
- RNA is single stranded while DNA is double stranded
- RNA is found in both nucleus and cytoplasm while DNA is only in nucleus
- DNA contains deoxyribose while RNA contains ribose
