A chemical reaction happens
The correct answer is a cell.
The basic life building block is the cell.
The cell is termed as the biological, functional and structural unit of every living organisms. They are referred to as building blocks.
Cell biology is the study of cell. Cytoplasm is being found in the cell which is enclosed in a membrane. The biomolecules which are contained in a cell include nucleic acids and proteins.
There are organisms which contains single cell for example, bacteria and those which are multicellular for example, animals and plants.
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:
it can be found in higher plants and embryonic stem cells in animals
