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.
DNA is divided into functional units called genes. A gene (def) is a segment of DNA that codes for a functional product (mRNA, tRNA, or rRNA). Since the vast majority of genes are transcribed into mRNA and mRNA is subsequently translated into polypeptides or proteins, most genes code for protein synthesis.. During protein synthesis, the order of nucleotide bases along a gene gets transcribed into a complementary strand of mRNA which is then translated by tRNA into the correct order of amino acids for that polypeptide or protein. 2.
