What is mitosis?

Back

Mitosis is the process of cell division that results in two identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What is meiosis?

Back

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four genetically diverse gametes.

Front

How are mitosis and meiosis similar?

Back

Both processes involve cell division and require DNA replication before the division occurs.

Front

What is ATP?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, used to power various cellular processes.

Front

What is a contractile vacuole?

Back

A contractile vacuole is an organelle in some protists that helps to expel excess water from the cell.

Front

What is a Paramecium?

Back

A Paramecium is a single-celled organism (protist) that moves using cilia and lives in freshwater environments.

Front

What is the role of mRNA?

Back

mRNA (messenger RNA) carries genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What are amino acids?

Back

Amino acids are the building blocks of proteins, linked together by peptide bonds.

Front

What is the function of ribosomes?

Back

Ribosomes are the cellular structures where protein synthesis occurs, translating mRNA into amino acid sequences.

Front

What is the significance of nitrogen bases in DNA?

Back

Nitrogen bases (adenine, thymine, cytosine, guanine) pair up to form the genetic code in DNA.
