What is the germ line?
The germ line is a cell line that consists of cells used to pass the genetic heritage of the next generation. These cells, known as germ cells, include gametocytes that produce eggs and sperm, as well as eggs and sperm themselves and gametogonia, cells that lead to gamenetocytes. The bacteria line is a continuous chain of inheritance that can be traced after many generations. As the cell begins to divide and evolve into an embryo, the germ cells are specifically postponed; These cells will later generate eggs or sperm in an adult organism to eventually become embryo. Cells that are not Germ, known as somatic cells, become different structures in the body. Somatic cells contain complete copies of the genome, but are distinguished to perform various functions, evolve into neurons, muscle cells, bone cells, etc., they are not part of it. Mutations to somatic cells cannot be transferred to future generations, while changes in the lines of germs will be maintained. SomeThe scientists believed that this could be valuable for gene therapies; In the therapy of the germ line gene, changes in the cell line that contain genetic information that will be passed could be made.
mutation of the germ line will not affect the body of the body in which the mutation occurs, but will have an impact on the offspring of the organism. For example, if the problem occurs during the production of eggs or sperm and that specific eggs or sperm become part of Zygot, this problem will affect the child. A simple example of such a mutation is a trisomy in which someone inherits three chromosomes instead of two, because two chromosomes were not separated during egg or sperm cells.
In the addituration line, which is interesting from a medical point of view, it also provides a large amount of information about heritage. Changes can be monitored through the germ line to learn more about the history of orgaNism, and this line of cells can also be used to look at the relationships between different groups of individuals. For example, people share a common line of bacteria, although they were different in a number of directions because new human generations were born.
