What is the inducer molecule in the lac operon?

Biology
1 answer:
Sunny_sXe [5.5K]2 years ago
4 0

Answer:

Allolactose

Explanation:

  • <u>The inducer in the lac operon is allolactose. Allolactose is the inducer of lac operon since it turns on, or induces the expression of the lac genes. </u>
  • In the presence of lactose in the medium, some amount of lactose will be converted to allolactose by the enzymes β-galactosidase present in the cell.
  • Consequently Allolactose binds to the repressor molecule, hence reducing the repressor's affinity for the operator site.

Which was an argument used to dispute the theory of plate tectonics?
Liono4ka [1.6K]

Answer:

Option D, Continents cannot cut through the ocean floor.

Explanation:

It was believed earlier that oceans were the land bridges that used to connect  different geologic plates of planet earth earlier, had now sank down and thus there exists no connection between the tectonic plates. Therefore,  without any link or connection, continents cannot cut through the ocean floor.

Also as per the Land Bridge Theory , there has been continuous shifting of dry land due to which identical land species on different continents were found.

Hence, option D is correct

Consider the cell cycle; which stage takes pretty much the same amount of time regardless of cell type? Explain
Natalija [7]

Answer:

The correct answer would be mitosis or M phase.

Mitosis or M phase is the phase of the cell cycle during which the actual division of the cell takes place that is, the division of nuclear content. It is also termed as karyokinesis.

It is primarily divided into four stages:

  • Prophase
  • Metaphase
  • Anaphase
  • Telophase.

It results in the equal distribution of  chromosomes into two daughter cells.

It is followed by cytokinesis by which cytoplasmic content is equally divided into the two daughter cells.
