Role of early genetic engineering for animal

Explanation:

Genetic engineering is the process of artificial alteration or manipulation of the original genetic makeup of an organism and then modification and recombination using technologies like the DNA recombinant technology.  

Early genetic engineering began with expressing specific bacterial genes by Cohen in 1973. Later due to various anxieties arising about hazardous reshaping of genetic systems, it came to a slowdown.

Then all these anxieties were subdued with the advent of DNA recombinant plasmid-based technology which was very helpful to understand the molecular genetic mechanisms in animals.

In animals genetic engineering is mainly used to find genes responsible for beneficial traits or characters introduce them into another animal’s genome and create a new offspring with the beneficial character.

The first animal which was created by genetic engineering was a mouse by Rudolf Jaenisch in 1974. Later many transgenic animals were developed like chicken, mice, cattle, sheep, pig etc.  

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
