DNA and the Genetic Code Flashcards
What does DNA stand for?
Deoxyribose Nucleic Acid
What does DNA do?
Determines which amino acids are linked together
What discovered DNA?
Francis Crick and James Watson in 1953
What is the structure of DNA
Double Helix - two chains are twisted together which are joined by bases
What molecules do DNA have?
Two long chains of sugar and phosphate molecules
What are the four bases and spell them?
Adenine
Cytosine
Guanine
Thymine
What do bases do?
Forms a code which different amino acids produce proteins
What bases go together?
Adenine and Thymine
Cytosine and Guanine
Three bases code for…
One amino acid called the triplet code
How does DNA code for the formation of proteins?
The order in which bases occur along a DNA strand
forms a ‘code’ which determines how different
amino acids are linked together to form different proteins.
