In the lac operon, the repressor:a. binds to allolactose and becomes active, blocking lac gene expression.b. binds allolactose a
Vladimir79 [104]

Answer:

c. binds to allolactose and becomes inactive, allowing lac gene expression to occur.

Explanation:

Interaction between allolactose and repressor leads to allosteric repulsion which makes repressor inactive leading to the lac gene expression. This is the reason why allolactose is known as the inducer of lac operon becasue it causes gene expression in lac operon.

In the absence of allolactose, the repressor binds the operator and does not allow RNA polymerase to do transcription.

labwork [276]

A taxon is a general term that describes any level of the biological classification system scientists use for living things.

<h3>What is a taxon?</h3>

A taxon (plural - taxa) is a term used by taxonomists or biologist to describe a taxonomic group of any rank.

The taxonomic groups we have in biological classification are as follows:

  1. Kingdom
  2. Division
  3. Class
  4. Order
  5. Family
  6. Genus
  7. Species

Any of the above ranks in taxonomic classification can be regarded as a taxon.

Therefore, a taxon is a general term that describes any level of the biological classification system scientists use for living things.
