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.
Gametes, or sperm and egg cells are both haploid cells, meaning that they have half the amount of chromosomes that regular body cells do, meaning that the sperm cell of this bird would have 32 chromosomes.
Answer:
It is the cerebellum that processes information received from the cerebral motor cortex, brain stem nuclei, and various sensory receptors, and then uses this information to coordinate balance, posture, and somatic movement problems
Explanation:
Cerebellum is a vital brain part that regulates all motor movements. It processes all the information received from spinal cord and sensory system to co-ordinate voluntary movements thereby resulting into smooth and balanced muscular activity.
It is just the ten percent of brain size but consists of almost 50% of the brain's neurons which are specialized cells in transmitting information via electrical signals.
Hence, It is the cerebellum that processes information received from the cerebral motor cortex, brain stem nuclei, and various sensory receptors, and then uses this information to coordinate balance, posture, and somatic movement problems
