CAN ANYONE DECODE THIS?

This is not a trick question. In order to solve this problem you will need to be familiar with how computer memory stores digital information. You will also need to have knowledge of an extremely simple encryption method. With these at your disposal it should not take long to decode the message.
Can anyone decode this?

HDKFHQFE-P genome sequence?

Why would a piece of genetic code have anything to do with " how computer memory stores digital information"?
-
JWB
cantleave, here is a clue: base 4 - as opposed to binary/hexadecimal/octal.
-

The codons are for .....
CAT = Histadine
GAC = Aspartic acid
AAA = lysine
TTT = Phenylalanine
CAC = Histadine
CAA = Glutamine
TTC = Phenylalanine
GAA = Glutamate
TAG = Termination (amber)
GCC = Alanine

cantleave, please reread my original post. This is an encoded message using the letters ACGT to form base 4 values.

I posted the above before seeing your hint ;-)

Another hint: Each individual part of the code is a pair.

falseprophet, well done!
And for those of you still wondering:
AA = _
AC = a
AG = b
AT = c
CA = d
CC = e
CG = f
CT = g
GA = h
GC = i
GG = j
GT = k
TA = l
TC = m
TG = n
TT = o
d n a _ c o d e _ o f _ l i f e
CA (d) TG (n) AC (a) AA (_)AT (c) TT (o) CA (d) CC (e) AA (_)
TT (o) CG (f) AA (_)
TA (l) GC (i) CG (f) CC (e)
This can also be used to store numbers too in base 4:
AA = 00 (0)
AC = 01 (1)
AG = 02 (2)
AT = 03 (3)
CA = 10 (4)
CC = 11 (5)
CG = 12 (6)
CT = 13 (7)
GA = 20 (8)
GC = 21 (9)
GG = 22 (10)
GT = 23 (11)
TA = 30 (12)
TC = 31 (13)
TG = 32 (14)
TT = 33 (15)---
Here is a real world example of using actually encoding secret messages into DNA. "These messages used codons, groups of three letters which code for amino acids, to stand for 20 letters of the alphabet. As such, some substitutions (like āvā for āuā) were necessary":

An interesting idea for synthetic data storage within DNA:
