in eukaryotes, RNA is synthetised in the nucleus from DNA, using RNA-polymerase.
in prokaryotes, RNA is synthetised in the cytoplasm (DNA has no nucleus), using RNA-polymerase as well.
The RNA molecule is usually made up of a single strand. This is unlike the DNA molecule which has double strands.

in humans there is one strand of RNA, hence the name single-stranded RNA. However, in some viruses (such as HIV), there are double-stranded RNA made by the enzyme transcriptase.
No, protein is not made out of RNA strands. Proteins are composed of amino acids, while RNA is a nucleic acid that plays a role in protein synthesis. RNA is involved in translating the genetic information encoded in DNA into the sequence of amino acids that make up proteins.

Ribosomes. Ribosomes are made up of two subunits, each of those are made up of strands of rRNA and protiens.
Generally, RNA is single stranded, but there are exceptions, especially in catalytic RNA.
