In regulation by repression Multiple Choice an amino acid activates the repressor so that the repressor binds to the operator an
Artyom0805 [142]

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.

Which of the following features did whales possibly inherit from a four-legged ancestor?
pishuonlain [190]

Answer:

2. Hip bones

Explanation:

More than 40 million years ago, whales had ancestors who walked on land. Even now, they have a feature they inherited from them - hip bones. Scientists used to think that they are vestigial, i.e. that they lost their function. However, recently they discovered that these bones help whales (and other marine mammals who have them, such as dolphins) maneuver better mating.

Whales developed the rest of the listed features later, when they became marine animals. This is why they are incorrect.
