Direction and Displacement would be your answer.
The lac repressor protein is bound to the operator region of the lac operon when there is no lactose in the medium. When introduced in lactose, it binds to an allosteric site on the repressor causing its to change conformation and release from the operator. This allows the polymerase that is bound to the promoter region to proceed transcription of the lac operon genes (LacZ, Lac A, and Lac Y). Translation of these genes forms enzymes that enable the organism to break down lactose for energy.
Answer:
All of the genes controlling the traits behaved as if they were located on different chromosomes.
Explanation:
Mendel's experiments with pea plants lead to two principles:
- Law of segregation which states that the pair of alleles (for any trait) of each parent separate, meaning that one allele passes from father and another from mother to an offspring.
- Law of independent assortment which states that different pairs of alleles (for different traits) are passed to offspring independently of each other (traits are located on different chromosomes).
Answer:
Lysosome - Janitor, cleans up food particles, waste, and dead cell parts.
Nucleus - Principal, contains DNA and is the control center for the cell.
Cell Membrane - Basically the walls of the school building
Ribosomes - Cafeteria Workers, creates "food" by combining amino acids.
Hope this helps!
