The Genetic Code

U C A G


By Bhoj Dewangan (M.Sc. Biotech)

Genetic code is very difficult to remember for any people, we are providing a trick so that you you can easily remember the Whole Genetic Code. See the structure of the Table

The arrangement of the codons in the table is in very specific order it is U C A G. It is kept in a special order

U            U            U            UUU

C            C            C            UUC

A            A            A            UUA

G            G            G            UUG

U            U            U            UCU

C            C            C            UCC

A            A            A            UCA

G            G            G            UCG

and so on

every cell is either coding only one type amino acid or two amino acids. Give no. to every cell either 1(coding one a.a.) or 2(coding two a.a.). see one exceptional cell having met

now take the numbers from the row- 2111(1st Row), 1111(2nd Row), 2222(3rd Row), 2121(4th Row)

(Please remember the position of Met, stop codon and Trp)

Remember the no.-2111,1111,2222,2121
