Answer:
mitochondria are in cells.
Explanation:
The mitochondria create the energy used throughout the cell, called ATP.
Answer: (B) Archaebacteria
Explanation: Archaebacteria, like all prokaryotes, have no membrane bound organelles. This means that the archaebacteria are without nuclei, mitochondria, endoplasmic reticula, lysosomes, Golgi complexes, or chloroplasts. Because<u> these organisms have no nucleus</u>, the genetic material floats freely in the cytoplasm.
Answer:
The correct answer is C. catalyze the removal of phosphate residues from proteins
Explanation:
The function of protein kinase is to transfer a phosphate group to the amino-acid present in a protein and the function of protein phosphatase is to catalyze the removal of the attached phosphate group from amino acid of a protein.
Protein dephosphorylation is an important event in the post-translational modification process. Through dephosphorylation, phosphatases change the protein behavior by activating and deactivating the proteins.
Phosphorylation and dephosphorylation of proteins are important in managing several crucial processes in the cell like cell signaling, apoptosis, cell cycle, etc. So the right answer is C.
Answer:
<em>Agrobacterium</em> <em>tumefaciens</em> is a gram negative bacteria that is responsible for tumor formation in the different parts of plant body.
Explanation:
It causes crown-gall disease in plant body by transferring it's DNA into the plant body which include Ti plasmid.
There are 3 types of bacteria that form tumor in different plant ares.
<em>Agrobacterium rhizogenes</em>,<em> Agrobacterium tumefaciens</em> strains contain either Ti or Ri plasmid but <em>Agrobacterium vitis</em> contain only Ti plasmid which are virulent.
The transfer of T-DNA takes place into the body of host cells and then the DNA is expressed into the body of the host and thus forming gall or tumor.
