1 the set of exogenic (physical, chemical and biological) processes that alter the physical and chemical state of rocks at or near the earth's surface.  intensity of most weathering decreases with depth, because variations in temperature and moistures decrease with depth.
A gene is a segment of nucleic acid that contains the information necessary to produce a functional product, usually a protein. Genes consist of a long strand of DNA (RNA in some viruses) that contains a promoter, which controls the activity of a gene, and a coding sequence, which determines what the gene produces.
Rating Newest Oldest. Best Answer: A gene is a section of DNA that produces a protein. The gene is composed of a sequence of DNA bases (ACT and G). Each 3 consequtive bases (called a codon) in the gene codes for a single amino acid to be strung onto the protein chain.Codons for cysteine, methionine, proline and tyrosine are TGT, ATG, CCT and TAT respectively.ating Newest Oldest.
