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.
The word mutation means a change in the genetic composition of a cell. Mutations can be divided into two main groups. The first group is gene mutations. These are chemical changes in the DNA [DNA: The material inside the nucleus of cells, carrying genetic information.DNA stands for Deoxyribonucleic Acid.] of the cell. A gene mutation is a change in the order of bases on a strand of DNA.riginal gene structure. This shows the normal order of the bases for one of the strands in the area highlighted in the DNA molecule. Only one of the strands of DNA is involved in protein synthesis. A change from the normal order of bases leads to different types of gene mutation.
