Meiosis. Sexual recombination. Crossing over. Independent assortment. Mutations.
The two MAIN sources would be genetic(sexual) recombination and mutations. Mutations allow for genetic variation, while genetic recombination allows for genetic shuffling. :)
Answer:
An amino acid activates the repressor so that the repressor binds to the operator and prevents transcription.
Explanation:
In an operon, promoter is followed by operator which is finally followed by the structural genes to be transcribed. RNA Polymerase binds to the promoter and initiates transcription. A repressor can negatively control the transcription process by binding to the operator so that the RNA Polymerase is not able to move forward and transcription is halted.
For example: in trp operon, tryptophan amino acid binds to the repressor molecule which leads to change in repressor's shape. The repressor is now able to bind to the operator and prevent transcription.
Plants perform cytokinesis differently than animals because plant cytokinesis takes place during interphase but animal cytokinesis takes place in cell division.
> Unlike animal cells, plant cells have a cell wall which needs to be divide or split up.<span>
>Mitosis and cytokinesis are two different things; mitosis is the division of the components of the nucleus, whereas cytokinesis is the division of the
cytoplasm and its constituents.
Thus, the answer is letter A.</span>
