Community of organism is a group of different species living or around each other in the same habitat.
Answer:
Transcription
Explanation:
This is the process by which the information contained in the DNA is copied by base pairing to form a strand of ribonucleic acid called messenger RNA. During transcription, the portion of the DNA with the organic bases required for the synthesis of the required protein open up. Free RNA nucleotides align opposite one of the chains in a complementary relationship. Guanine of RNA pairs with cytosine of DNA. Adenine of RNA pairs with thymine of DNA while uracil of RNA pairs with adenine of DNA.
If the lac repressor were altered so it could not release lactose once lactose was bound to it then you would predict that " the repressor could not bind to DNA".
<u>Option:</u> A
<u>Explanation:</u>
A DNA-binding proteins prevent gene expression coding for proteins engaged in bacterial lactose metabolism is understood as the lac repressor.
Such genes are repressed if lactose is not accessible to the cell, meaning that when lactose is available, the bacterium only spends energy in the development of machinery required for the absorption and processing of lactose.
When lactose is accessible, it is transformed into allolactose, which prevents the DNA binding ability of the lac repressor and thus increases the gene expression.
