Genes Make Up About What Percent Of DNA?

When trying to work out the percentages of genes found in DNA, it is worth looking at how the body’s cell structure works. DNA is an acid that contains all the genetic instructions used in the development of all living organisms and acts like an instruction manual or blue print which stores long term information. DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. The DNA segments that carry all genetic information in the body are made from genes.

In 1909, Danish botanist Wilhelm Johanssen coined the word gene for the hereditary unit found on a chromosome. A gene is the basic physical and functional unit of heredity. Genes act as instructions to make molecules called proteins. In humans, genes vary in size from a few hundred DNA bases to more than two million bases. The Human Genome Project has estimated that humans have between 20,000 and 25,000 genes in their body. Within cells, DNA is organized into long structures called chromosomes. These chromosomes are duplicated before cells divide in a process called DNA replication.

So when working out how many genes make up DNA the answer can be varied if a little unsure due to the huge amount of information which must be analyzed and the many variants involved. Most research and writings point to the fact that genes make up only around one  to 10 per cent of DNA, though according to the well renowned Prentice Hall Biology text book 2008 edition, it claims that only two percent of DNA is made up from genes.

Its A. 2%.  I'm taking Medical Billing in Coding online through Penn Foster Online and I'm in this chapter. If you are in Penn Foster Online and in the course Medical Specialties it is on page 69 under The Human Genome Project, 6 lines up from the bottom.

Speaking of medical billing. I know I heard about a fairly good company that provides medical billing services for various medical professionals. Maybe you should try to contact this medical billing company? It seems this company is pretty good.
