What are the first three features of DPLANT?
Degenerate - more than one code for each of the 20 amino acids produced. Punctuated - start and stop signals from codons. Linear - runs in sequential order.
1 of 8
What are the last three features of DPLANT?
Almost universal - all cells with DNA have the triplet code apart from prokaryotes and chloroplasts. Non-overlapping - triplets are in definite blocks of three. Triplet - each of the 20 amino acids represented by triplets.

What is a gene?
Section of DNA containing coded information for making polypeptides
3 of 8
What does a gene do?
Determines proteins of an organism from sequences of amino acids.
4 of 8
What is the triplet code?
Every 3 base pairs make up a codon which codes for an amino acid
5 of 8
What results due to 4 different bases?
Different orders of bases, different amino acid orders, different proteins
6 of 8
What happens in there is a change in base order?
Change in base order = change in amino acids = change in bonds = change in tertiary structure = different protein shape formed = may not work
7 of 8
What is an intron? How do they make genetic disorders?
Has no code for amino acids. If codes are in the wrong order due to introns, genetic disorders occur.
