Comets travel in orbits around the Sun. Some comets take less than 200 years to orbit the Sun. They are called short-period comets. Short-period comets are thought to originate in the Kuiper Belt, which is a belt of icy objects just beyond the orbit of the planet <u>NEPTUNE</u>. The dwarf planet <u>PLUTO </u>is located in this belt.
Explanation:
Comets are composed of ice, dust and gas. Comets are categorized into two kinds: short period comets (P < 200 years) which come from Kuiper belt and long period comets (P >200 years) come from Oort clouds.
Kuiper belt resides beyond the orbit of the planet Jupiter. Kuiper belt contains many objects Comets, asteroids and dwarf planets. Pluto which is a dwarf planet is located in Kuiper belt. Earlier it was considered as a planet but demoted to a dwarf planet in 2006.
In carrying out these experimental procedure, the same restriction enzyme that is used to cut out the gene of interest should also be the same used for the cutting of the plasmid to generate sticky ends. Then the desired gene is inserted into the cut plasmid then treatment with DNA ligase. Purified DNA ligase is utilized in gene cloning to join/ligate DNA molecules together forming a recombinant DNA. Thus, step 3 should be carried out after step 4.
