DNA Flashcards
(20 cards)
What are DNA’s nucloetides?
- ) phosphate group
- ) 5 carbon sugar
- ) nitrogenous bese
- Adenine (A)
- Thymine (T)
- Guanine (G)
- Cytosine (C)
What does DNA stand for?
Deoxyribonucleic acid
DNA in living things:
A’s pair with T’s and G’s pair with C’s
Genetic code-
Order and arrangement of DNA bases that determine the characteristics.
Purines-
Bases that have a double ring structure (adenine and guanine)
Pyrimidines-
Bases that have a single ring structure (thymine and cytosine)
Codon-
every 3 mRNA base for one amino acid
Anticodon-
3 tRNA bases which join the codon
Intron-
Sequences of nucleotides not involved in building proteins
Exon-
Sequences of nucleotides expressed to go on to form a protein.
Translation-
When mRNA, tRNA, and ribosomes interact to form protein.
GUA
Valine
CUU
Leucine
AGG
Arginine
UUU
Phenylalanine
AUG
Methionine
ACG
Threonine
UGU

How do you know what amino acid is in the genes?
Find the mRNA by matching all the letters except use U instead of T and then match them with your chart
