explain how repressible and inducible operons differ and how those differences reflect differences in the pathways they control
Sonja [21]

Answer

Operons are cluster of coordinated genes, including structural genes, an operator gene, and a regulatory gene.

Explanation:

In the The repressible operons, The transcription is usually on and repressor is in inactive form, So the specific genes are transcribed. While a regulatory molecule act as corepressor and binds to repressor protein to activate it. The repressor protein cause the inactivation of repressible operon (as the name indicate). E.g., Tryptophan Repress the trp operon.

A high level of product act as regulatory molecule (Corepressor) and turn off the operon, So anabolic pathways or synthesis of essential components are controlled by repressible operon.

In the Inducible operons, the transcription is usually off and repressor is in active form. So there is no transcription of genes. Specific Metabolite cause the activation of operon  e.g lactose cause the induction of lac operon.

As a metabolite induces the operon, So they control the Metabolic pathways or breakdown of a neutrient.

Occasionally a child is born with an extra chromosome 13, but never do you see a child with an extra chromosome 12, why?
Morgarella [4.7K]

This is because some of the trisomies (one extra chromosome, three instead of two) are fatal, births cannot survive.

Theoretically, trisomies can occur with any chromosome, but often result in miscarriage.

The types of autosomal trisomy that survive to birth in humans are:

Trisomy 8 or Warkany syndrome 2

Trisomy 9

Trisomy 13 or Patau syndrome

Trisomy 18 or Edwards syndrom

Trisomy 21 or Down syndrome.
