how many strand dna have
DNA is double stranded, so 2. RNA is single stranded, so 1. DNA is located in the nucleus. RNA is located in a few places because there are different types of RNA....RNA is copied in the nucleus (mRNA), and then shipped out to a ribosome (which has rRNA and tRNA), floating in the cytoplasm. DNA has 2 strands, RNA just 1, and they both can be found in the nucleus of the cell.
