The creation of a panda reserve system in 1992 increased available habitats; today, there are 67 reserves in the country that protect 67% of the population and nearly 1.4 million hectares of habitat.
A gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people.Mutations range in size; they can affect anywhere from a single DNA building block (base pair) to a large segment of a chromosome that includes multiple genes. gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people.
Sometimes, expression of these genes hasan important effect on the host cell, altering it in novelways. The genetic alteration of a cellâs genome by the in-troduction of foreign DNA is called transformation. When the foreign DNA is contributed by a bacterial virus,the alteration is called phage conversion.
