Biology CB6 Flashcard-The Nucleus (M)

Front

What are long strands of coiled-up DNA and proteins called?

Back

Chromosomes

Front

Is the nucleus a membrane-enclosed organelle found in most prokaryotic cells?

Back

False

Front

What are chromatin made of?

Back

Chromatin are cellular parts made of DNA and proteins, not ribosomal RNA (rRNA).

Front

What do ribosomes direct after being exported to the cytoplasm?

Back

Protein synthesis.

Front

What is the process by which the information in a gene is decoded to produce a functional gene product?

Back

Gene expression.

Front

What is the primary function of the nucleus in a cell?

Back

The nucleus houses the cell's genetic material (DNA) and controls cellular activities.

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are responsible for synthesizing proteins by translating messenger RNA (mRNA).

Front

What is chromatin?

Back

Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus.

Front

What is the difference between prokaryotic and eukaryotic cells regarding the nucleus?

Back

Prokaryotic cells do not have a nucleus; eukaryotic cells do.

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.
