Amost all organisms have genes that are made of DNA (deoxyribonucleic acid) but there are some kinds of viruses known as retroviruses whose genes are composed of RNA (ribonucleic acid).

Genes are segments of DNA that contain the instructions for making proteins. RNA is synthesized from DNA and plays a key role in translating genetic information into proteins. Genes are composed of DNA, not RNA.
Genes are made up of DNA, which contains the instructions for building and controlling an organism's development and functioning. Genes are segments of DNA that code for specific traits or characteristics. Changes in genes can lead to variations in traits among individuals.
Viral chromosomes can be made up of either RNA or DNA. RNA viruses, such as influenza and HIV, use RNA as their genetic material. DNA viruses, like herpes and smallpox, use DNA as their genetic material.
DNA stands for deoxyribonucleic acid, while RNA stands for ribonucleic acid. DNA carries genetic information in the form of genes and is double-stranded, while RNA is involved in protein synthesis and is typically single-stranded. Both DNA and RNA are essential molecules for life and are made up of nucleotides.
The organelle that is made up of DNA and RNA in the nucleus is called the nucleolus. It is involved in the production of ribosomes, which are essential for protein synthesis in the cell.
Chromosomes are made up of DNA, proteins, and small RNA molecules. DNA contains the genetic information that is passed on from one generation to the next, while proteins help in structural support and regulation of gene expression. Small RNA molecules are involved in processes such as gene regulation and maintenance of chromosome structure.
