The forward and reverse PCR primers used for the amplification of a VNTR locus on chromosome number 4 are 20 bases and 21 bases
zimovet [89]

The repeats which occur together on a chromosome are referred to as VNTR. The length of each repeat is 60bp.

The first primer is 20bp and is 53 bp away from 1st repeat. Therefore, the total length of sequence amplified by the first primer till 1st repeat = 20+53 = 73bp. Beyond this point 6 repeats on 60 bp are present, hence, the length becomes = 73 + (60X6) = 433bp.

Now the reverse primer which is 21bp in length is located 28bp from the repeat on its side. Reverse primer comes from the opposite direction, so it must be present after the 6 repeats.

The total length of the amplified region = 433 + 28 + 21 = 482 bp.

</span>

<span>Phosphorus is not abundant in the atmosphere. It comes mostly from the land and ocean. Phosphorus cycle through the lithosphere, hydrosphere, and biosphere, but not the atmosphere. The reason for this is that phosphorus cannot be found in the gas state, unlike the sulfur. On the other hand, sulfur cycle partially occurs in the atmosphere.</span>
