How many human genes?

How many genes people have is a question that has not been answered correctly because of the difference between views and determinations of scientific groups in the world. The function of any gene is similar.

Although 10 years ago scientists successfully decoded the human genome, it is still unclear how many genes and genes each function has so far.

How many genes people have and what functions each gene has until now are still riddles.

According to the majority of documents, people have about 33,000 genes, which means less than one grape's genes (34,434 genes) but more than the number of genes of a hen (16,736 genes).

On the US National Institutes of Health database, the number of human genes is 22,333 genes, but another database shows 38,621 genes. British scientists temporarily recognize the number of 21,671 genes. In the catalog of genes of mammals drafted by many geneticists in the world, a lower figure is 18,877 genes.

The numbers are so big, because the gene is only 1% out of 3 billion nucleotides, found in each person's DNA sequence. And they are not arranged in any order, a consistent rule, but a mixture of DNA, non-coding protid. Even inside each gene there is such a arrangement.

British geneticists have recently embarked on a project with the goal of determining the number of human genes more accurately. This work will basically be conducted manually. Computers only account for about 40% of tasks.
