Answer:
Complementary base pairing
Explanation:
DNA probes are the single stranded stretches of nucleotides that are complementary to the original strand. DNA probes are used in various molecular technologies like polymerase chain reaction and DNA finger printing.
DNA probes can only hybridize with the specific complementary base pairs. Hence, complementary base pairing determines the specificity of DNA probe.
Thus, the correct answer is option (D).
Answer:
domain and kingdom will have more number of organisms
Animal cell is a eukaryotic cell, it contains other membrane-bound organelles, or tiny cellular structures, that carry out specific functions necessary for normal cellular operation in living organisms such as humans and animals . Animal cells contain the following structures and organelles here is the list: Cell (Plasma) Membrane,Centrioles,Cilia and flagella,Cytoplasm,Cytoskeleton,Endoplasmic Reticulum,Golgi Complex, Lysosomes ,Microtubules ,Mitochondria , Nucleus,Peroxisomes & Ribosomes<span> </span>
Answer:
A. By releasing toxins that poison your cells
B. By using your cells to make copies of themselves
Explanation:
Within the body, bacteria can divide (multiply) and kill host cells by disrupting their normal functioning. Moreover, bacteria secrete toxins that are able to destroy host cells' metabolic machinery. For instance, many bacteria synthesize exoenzymes and interferons that disrupt and destroy host cells. Bacterial toxins can be synthesized internally in order to develop sensitivity through antigenic properties.
