Joint Function and Lupus. Joint pain or arthritis is experienced by 95 percent of people with lupus at some time during the course of their disease. In fact, joint pain is usually the first symptom of lupus. Unlike rheumatoid arthritis, the arthritis of lupus tends to be temporary.It is also less damaging to the joints. The joints most commonly involved are those of the fingers, wrists, and knees.oint Function and Lupus.

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.he bases Adenine(A) and Guanine(G) are Purines; while Thymine (T) and Cytosine (C) are Pyrimidines. Genes are poly-nucleotides. Each nucleotide is made up of a base group, a sugar and one ore phosphate groups. The sugar group forms the backbone of DNA.
Genes code for the production for proteins. Some of these are enzymes which control how the cell functions. This slideshow demonstrates how a protein is produced using the genetic code.How a protein is produced using the genetic code. Genes contain bases in groups of three. Page: 1  1. 2  2. 3  Next. gene is a section of DNA which controls part of a cell's chemistry-particularly protein production. is a shorter region of DNA that carries the genetic code for a particular characteristic or cell activity. Nucleus, chromosome and gene. DNA molecules contain chemicals called bases.
