The codons that encodes amino acid serine are as follows:
- TCT,
- TCC,
- TCA,
- TCG,
- AGT,
- AGC
Mutations are spontaneous and occur at random however there are some mutagenic agents which increase the chance of this happening such as radiation exposure. If it is a point shift mutation then only a few bases on the dna sequence are changed so only changes a few of the amino acids in that chain (such as inversion of a base). If its a frame shift then the base sequence is altered so much so that every amino acid from after that changes (such as deletion of a base) which can create things such as cri-du-chat syndrome which results from a piece of chromosome 5 is missing. Hope this helps:)
Increased use of antibiotics since the few that are immune will survive and reproduce and will out grow others that arent.
