Biology Benchmark (most missed)

Front

What is the process by which DNA is transcribed into mRNA?

Back

Transcription is the process where a segment of DNA is copied into mRNA by the enzyme RNA polymerase.

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are the cellular structures responsible for protein synthesis, translating mRNA into amino acid sequences.

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 the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and membrane-bound organelles.

Front

What is mitosis?

Back

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

Front

What is the function of mitochondria?

Back

Mitochondria are known as the powerhouse of the cell, generating ATP through cellular respiration.

Front

What is the significance of the cell wall?

Back

The cell wall provides structural support and protection to plant cells, fungi, and some bacteria.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs light energy, primarily from the sun, to drive the photosynthesis process.

Front

What is the function of RNA in cells?

Back

RNA plays several roles in cells, including acting as a messenger (mRNA), a component of ribosomes (rRNA), and a carrier of amino acids (tRNA) during protein synthesis.

Front

What is the outcome of meiosis?

Back

Meiosis results in four genetically diverse gametes, each with half the number of chromosomes of the original cell.
