DNA is a polymer made up of DNA Nucleotides. A Nucleotide consists of a phosphate, deoxribose sugar and a base (C,G -3, T, A -2)

What Do we mean when we say DNA is Universal?
The same codon codes for the same amino acid in all organisms
2 of 7
What do we mean when we say DNA is Degenerate?
Means that most amino acids have more than one codon
3 of 7
What do we mean when we say DNA is Non-Overlapping?
Each base in the sequence is read only once.

What is mRNA?
Messenger RNA, involved in Transcription. Single stranded, linear structure, no hydrogen bonds, RNA nucleotides, A,U,G,C, not very stable
5 of 7
What is tRNA?
Transfer RNA, involved in Translation. Single stranded, clover shape, RNA nucleotides, hydrogen bonds, A,U,G,C, more stable than mRNA

How are proteins made from the DNA code?
Proteins cannot be made where the DNA is - inside the nucleolus so the code needs to be copied out - this is translation, since we now have the opposite code we covert it once more in the ribosome with the help of tRNA to form proteins
