Biology Fall Final Review

Front

What are ribosomes?

Back

Ribosomes are cellular structures that synthesize proteins by translating messenger RNA (mRNA) into polypeptide chains. They can be found in both prokaryotic and eukaryotic cells.

Front

What happens if cells bypass regulatory checkpoints in the cell cycle?

Back

If cells bypass regulatory checkpoints, they may divide uncontrollably, leading to tumor formation and cancer.

Front

What is the process of translation?

Back

Translation is the process where messenger RNA (mRNA) is decoded by ribosomes to form a polypeptide chain, which will fold into a functional protein.

Front

What causes the change in fur color of the arctic fox?

Back

The change in fur color of the arctic fox is caused by gene expression for fur color being regulated by temperature.

Front

What is transcription?

Back

Transcription is the process where DNA serves as a template to create RNA, specifically messenger RNA (mRNA).

Front

What is the main difference between prokaryotic and eukaryotic cells?

Back

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

Front

What role do Golgi bodies play in a cell?

Back

Golgi bodies are responsible for modifying, sorting, and packaging proteins and lipids for secretion or delivery to other organelles.

Front

What is the function of mitochondria?

Back

Mitochondria are known as the powerhouse of the cell, as they generate adenosine triphosphate (ATP) through cellular respiration.

Front

What is the significance of the cell cycle?

Back

The cell cycle is crucial for growth, development, and repair in organisms, as it regulates cell division and ensures proper DNA replication.

Front

What is gene expression?

Back

Gene expression is the process by which information from a gene is used to synthesize a functional gene product, typically a protein.
