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.
RNA, which stands for ribonucleic acid stores and transmits genetic information that is vital for the manufacture of proteins. It carries this information from DNA, which is housed inside the cell nucleus, to the ribosomes. These can be found in the cytoplasm and are the 'factories' which make the proteins. Inside the nucleus RNA transcribes the genetic information by producing a complimentary nucleic acid strand - a copy of a DNA sequence. When it reaches the ribosomes the information is translated to produce a protein.
