The amino acids coded triplets in the 3' to 5' strand on the normalp53 gene of chromosome 13 are lysine, leucine, Glutamine, stop codons.

Explanation:

mRNA is formed by the transcription of DNA strand coding for  a gene.

Any mutation in the DNA sequence even a difference of base pair would cause formation of different amino acids and hence altered protein.

The amino acid is formed in the step of translation where codes are read by tRNA on the mRNA strand and correct nucleotide is brought to growing polypeptide chain.

In transcription 3' to 5'  strand acts a template strand. The amino acids on the p53 gene of chromosome 17 is

3'TTT AAC   GTC    ATC 5'    Gene sequence

9966 [12]

The correct answer would be humus.

Humus is the organic material of the soil formed by the decomposition of the dead plants and animals. It is thick and dark in color (brown or black) and can also be produced by the process of composting.

It is very for the soil as it adds moisture to the soil, enhances the structure of the soil which increases the aeration and drainage.

It favors the growth of organisms (such as earthworm) helpful for the growth of plants and adds lots of nutrients to the soil, specially nitrogen.

In contrast, loam is a type of soil which is composed of silt, sand, and clay in 40-40-20 ratio. Regolith referred to the superficial layer covering the solid rocks or bedrock. It is formed by the accumulation of soil, dust, broken rocks etc on the bedrock.

Lastly, talus referred to the slope which is formed by deposition of shattered rock debris at the base of a cliff.
