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.

What are the processes of biomass production in generation of gas. in a comprehensive way pls.​
zhuklara [117]

Thermochemical conversion is a process which is used to produce solid, gaseous, and liquid fuels.

<h3>What are the processes of biomass production in generation of gas</h3>

Biomass is converted into energy through various processes such as Direct combustion means burning to produce heat. Thermochemical conversion is a process which is used to produce solid, gaseous, and liquid fuels while on the other hand, Chemical conversion is a process to produce liquid fuels.

So we can conclude that thermochemical conversion is a process which is used to produce solid, gaseous, and liquid fuels.
