The life-form during the Precambrian time was cyanobacteria.
The ribonucleic acid sequence of the above gene is GGU UCG AGA and therefore according to the genetic code, the sequence codes for the Glycine, Serine and the Arginine amino acid.
The order is; Gly-Ser-Arg
Glycine is also coded by these codons; GGC, GGA, and GGG
Serine amino acid is also coded by the codons; UCU, UCC, UCA, AGU, and AGC
Arginine is coded by these codons; AGG, CGU, CGC, CGA, and CGG
