Explanation:
Multicellular organisms begin as a single cell. These cells then grow and undergo differentiation, the process by which cells develop specialized forms and functions.In multicellular organisms, cells are often organized into tissues, organs, and organ systems.
Answer:
The correct answer is option c. "frameshift mutations".
Explanation:
The reading frame of a gene is based on base-pair triplets, starting from the start codon until the ribosome encounters with the end codon. Base-pair additions and deletions are collectively referred to as frameshift mutations because they alter the reading frame of the gene. Base-pair additions and deletions break down the original sequence of the gene triplets, which alters the open reading frame and usually results in the production of non active proteins.
This drug inhibits the growth of bacterial cells but not human cells. This is an example of the selective toxicity of antibiotics.
Folic acid is an essential component for all cells to synthesize nucleic acids (DNA and RNA). Human cells do not synthesize folic acid and they take it through food. Bacterial cells are impermeable to folic acid and hence they need to synthesize their own folic acid.
Antibiotics target the metabolic pathway of folic acid synthesis in bacteria by inhibiting one of the enzymes in this pathway. These drugs are only toxic to bacteria but not to humans because humans do not have the folic acid synthesis pathway and hence they do not get affected by the action of the antibiotic. This is known as the selective toxicity of antibiotics.
These antibiotics are designed in a way to target the infecting agent (bacteria) while rendering minimal or no toxicity to the host (humans).
