Ribose
Hydrogen bonds
WEAK; bonds between nitrogen bases
WEAK; bonds between nitrogen bases
Hydrogen bonds
Covalent Bonds
STRONG; bonds of everything BESIDES the nitrogen bases hold together the phosphates and sugar
STRONG; bonds of everything BESIDES the nitrogen bases hold together the phosphates and sugar
Covalent Bonds
Peptide bonds
a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water

Peptide bonds
Semi-conservative
PART of the molecule is being conserved for the new ones (in DNA replication each new strand has some old and some new)
PART of the molecule is being conserved for the new ones (in DNA replication each new strand has some old and some new)
Semi-conservative
Nucleotide
the basic building block of nucleic acids (monomers)
the basic building block of nucleic acids (monomers)
Nucleotide
Where and when does DNA replication take place?
In the nucleus during the S phase of interphase
Know the key differences between DNA and RNA (sugars used, shape, bases, etc)
DNA- Deoxyribose, double helix, nitrogen bases of A, T, C, G
RNA- Ribose, single strand, nitrogen bases of A, U, C, G
What are the base pairing rules?
A’s bind with U’s
C’s bind with G’s
What type of bonds hold DNA together?
hydrogen
What does it mean if the DNA is semi-conservative?
part of the old molecule is conserved/saved
Polypeptide
A chain of amino acids that can bind to others and fold into protein
A chain of amino acids that can bind to others and fold into protein
Polypeptide
Ribosome
An organelle made of both RNA and protein, and it is the site of protein synthesis in the cell
