Group of genes that are regulated together
Genes usually have related functions
E. coli <span>have cluster of 3 genes that must be turned on before it can use lactose as food</span>
Answer:
The correct answer would be B) enclosed in a protein capsule
Almost all living cells contain DNA as their genetic material. DNA control and coordinates the function of the cell. The two cells also must contain the DNA.
Cellular respiration refers to the set of biochemical reactions by which the cell generates ATP or energy. All the living cells produce energy through cellular respiration, however, they may utilize the aerobic or anaerobic form of respiration.
A ribosome is found in all the living cells including animal cells, plants, bacteria et cetera. They form the site for protein synthesis in all the cells.
The protein capsule is not a universal feature of all living cells. Thus, it may be present in one cell type and absent in another cell type.
That would be catalysts.
Catalysts accelerate (speed up) chemical reactions without damaging itself. They do this by decreasing the activation energy of a chemical reaction.
Enzymes are a type of catalysts.
It is the cell’s powerhouse and processes energy for the cell.
I was told to remember it as the main brain or the head honcho.Hope this helps.
Answer: D.) This gene sequence ensures transcription of arabinose genes only
when arabinose is available, saving the cell from expending energy
unnecessarily
