Answer: Bottom layer of rock
Explanation:
The bottom layer is the layer of the deposition of the sediments in which sedimentation and cementation occurs to form the rocks. These rocks are formed at the lowest horizon of the soil profile. These rocks are also called bedrocks. The layer present above the rock are younger and the layer at the top is the youngest layer. The older layer at the bottom and the younger layer at the top. This phenomena is called law of superimposition.
They are both used to benefits plants growth process.
Lock and Key forms “lock and key enzymes”
Answer:
the three-base sequence of mRNA
Explanation:
Translation is the process of formation of proteins. Translation process is achieved with the help of ribosome, which links amino acids in the order defined by messenger RNA (mRNA), using RNA (tRNA) transfer molecules to hold amino acids and read three nucleotides at a time of the mRNA.
The three-base sequence are present in mRNA called codons or mRNA nucleotide triplet sequences are specific to a amino acids for proper function. For exmaple: AUG codon , specifies the amino acid methionine which acts as starts codon and initiate the process of translation.
Hence, during translation, the characteristic that represents the three base sequences of mRNA is related to the coding of single amino acid.
