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.
Repressor slows down transcription.
RNA Polymerase enzyme transcribes mRNA from DNA.
Explanation:
Promoters are the 100 to 900 bps long sequence of DNA, that helps in the initiation of transcription. The transcription gets slow down as repressor bind to the promoter region hampering the attachment of RNA Polymerase enzyme which is responsible for transcription.
The process of transcription is the conversion of DNA into mRNA as told in the central dogma of molecular biology. Enzyme responsible for transcription is RNA polymerase. It is the first phase of gene expression, where DNA strand is copied into mRNA called a primary transcript.
Most bacterias are heterotrophs. Meaning they can't make their one good ( sadly :3)
