Review 5: DNA

Front

What is DNA?

Back

DNA (Deoxyribonucleic Acid) is the molecule that carries the genetic instructions for life, composed of two strands forming a double helix.

Front

What is the role of DNA in cells?

Back

DNA provides the instructions for protein synthesis, which influences the traits and functions of an organism.

Front

What are eukaryotic cells?

Back

Eukaryotic cells are complex cells that contain a nucleus and organelles, such as plants and animal cells.

Front

What are prokaryotic cells?

Back

Prokaryotic cells are simpler, unicellular organisms without a nucleus, such as bacteria.

Front

What is cell differentiation?

Back

Cell differentiation is the process by which a less specialized cell becomes a more specialized cell type.

Front

How do environmental factors influence cell differentiation?

Back

Environmental factors can influence gene expression, leading to changes in cell differentiation.

Front

Why is accurate DNA replication important?

Back

Accurate DNA replication ensures that each daughter cell receives a complete set of genetic information during cell division.

Front

What is the significance of the nucleus in eukaryotic cells?

Back

The nucleus houses the cell's DNA and is responsible for regulating gene expression and cell division.

Front

What is the primordial soup theory?

Back

The primordial soup theory suggests that DNA originated from simple organic molecules in the early Earth's oceans.

Front

What is protein synthesis?

Back

Protein synthesis is the process by which cells use DNA instructions to create proteins, which perform various functions in the body.
