Psoriasis isn't contagious, you get it from your family genes.
In some cases a relative may have psoriasis from yet another relative, from smoking, or from stress. It doesn't have to be your mother or father that could pass it, but you can get it from your grandma or grandpa. Anyhow the genes pass from relative to relative ( psoriasis changes your genes ) and affects you.
They get dry itchy patches of skin.
The cause of psoriasis remains largely a mystery. But it's likely that the interplay between genes and triggers is a big part of the story. Researchers believe that psoriasis develops when something mistakenly triggers the immune system. And in psoriatic arthritis -- psoriasis that affects the joints -- both genetics and environmental factors seem to play a role.
No genes are involved. This is a viral disease carried by mosquito.
That will depend on what traits those genes control.
same
because it have two clases of genes involved: oncogenes and tumor suppressor genes
chromosomes and genes on my guess!!
Evolution is the result of a process called survival of the fittest. Genes are part of the mechanism by which this happens.

RNA itself does not contain genes, but RNA is involved in the expression of genes. RNA is transcribed from genes in the DNA and carries the genetic information to create proteins through a process called translation.
