Nuclear envelope, endoplasmic reticulum, the Golgi apparatus, lysosomes, and vesicles
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.
Answer:
Chimpanzees
Explanation:
Chimpanzees are much more closely related to humans in an evolutionary sense that cows are. Chimpanzees and humans are both primates, characterized by features like advanced cognition, grasping hands and feet, and front facing eyes. In contrast, cows belong to a different of bovine animals.
Because we are evolutionary more related to chimpanzees, that means our DNA has undergone less change over evolutionary time. That means that the sequence will be more similar to chimps
