The nitrogen oxides are not all bad. They are both used in the lead chamber process as catalysts to convert SO2 to SO3, which is the essential first step in the production of sulphuric acid. They are also precursors in the Ostwald Process for the manufacture of nitric acid (see below).
Single Gene Traits in Humans. The following is a list of some autosomal human traits that have been attributed to a single gene. Although clearly other genes are involved, the inheritance of each of these phenotypic traits acts as if it were governed by a single gene. First, indicate your expression of the trait (i.e., circle the appropriate phenotype).
It is the protein that determines the trait. This is called central dogma of life. Fig 1.a.2 Central dogma of life. Notes: Genes are DNA sequences instruct cells to produce particular proteins, which in turn determine traits. Chromosomes are strings of genes. Mutations are changes in gene's DNA sequence.
