Front

What is cancer?

Back

Cancer is a disease characterized by uncontrolled cell division, leading to the formation of tumors and the potential spread of abnormal cells throughout the body.

Front

What is the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through to grow and divide, including interphase (G1, S, G2) and mitotic phase (M).

Front

What is a lysogenic infection?

Back

A lysogenic infection is a type of viral infection where the virus integrates its genetic material into the host cell's DNA and can remain dormant for a long time.

Front

What is a lytic infection?

Back

A lytic infection is a type of viral infection where the virus immediately takes over the host cell's machinery to produce new viruses, leading to cell lysis (destruction).

Front

What are proteins?

Back

Proteins are organic macromolecules made up of chains of amino acids that perform various functions in living organisms, including structural support, transport, and catalysis.

Front

What are organic macromolecules?

Back

Organic macromolecules are large, complex molecules essential for life, including carbohydrates, proteins, lipids, and nucleic acids.

Front

What is the role of nucleic acids in cells?

Back

Nucleic acids, such as DNA and RNA, store and transmit genetic information, guiding the synthesis of proteins.

Front

What is the difference between living cells and viruses?

Back

The only characteristic shared by living cells and viruses is the presence of nucleic acid; viruses cannot carry out metabolic processes independently.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.
