Genetic information is carried in the linear sequence of nucleotides in DNA. Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held together by hydrogen bonds between G-C and A-T base pairs.
Answer:
When the lactose in absent then under such a situation the Lac repressor protein bind to lac operator and prevents the transcription of lac Z, lacY and lac A gene by the RNA polymerase. When the lactose is present then the allolactose binds to lac repressor and prevent repressor binding and the lac operon is called inducible.
When the concentration of lactose is high then at that time the lac operon is turned on and CAP is bind and bacteria is able to use lactose. When the concentration of lactose is low inside the cell under such a situation the lac operon is shut off and bacteria are not able to use lactose
Answer:
yes, yes it is.
Explanation:
The broad bands or regions located around the nucleus where the electrons are found are called energy rings. Research has shown that the electrons orbit the nucleus in circular motions exactly as shown on the classic Bohr model.
