Term
DNA
Definition
DNA stands for Deoxyribo1Nucleic Acid
Term
Nucleotides
Definition
Each nucleotides has 1 phosphate molecule, 1 sugar molecule,and 1 base molecule
Term
Base Pair rule
Definition
DNA is held together by two strands called hydrogen bonds. Adenine is always paired with Thymine and Cytosine is always paired with Guanine
Term
DNA Replication
Definition
A process by which the DNA copied itself during the cell cycle
Term
Unzipping
Definition
The first step of DNA Replication, and when the double helix begin to separate into two strands by enzymes called, helicase
Term
Baseparing
Definition
The second step of DNA Replication, and when the complementary bases find matches on newly exposed single DNA strands by free nucleotides
Term
Bonding
Definition
The third step of DNA Respiration, and new base pairs are bonded together to form double helix structure by enzymes called DNA polymerases
Term
Proofreading
Definition
The final step of DNA Respiration, and new DNA molecules is checked over to correct any errors called mutations by DNA polymerase enzymes
Term
Purines
Definition
Adenine and Guanine
Term
Pyramidine
Definition
Cytosine and Thymine
Term
Who discovered the double helix structure?
Definition
James Watson, Francis Crick, and Rosalind Franklin
Term
RNA
Definition
Stands for RiboNucleic Acid
Term
Uracil
Definition
Found only in RNA and is paired up with
Adenine
Term
Central Dogma
