Front

What is the function of the nuclear lamina?

Back

The nuclear lamina helps maintain the shape of the nucleus and provides structural support.

Front

Where are ribosomes found performing translation?

Back

Ribosomes can be found in the cytoplasm, chloroplasts, mitochondria, and attached to the rough endoplasmic reticulum.

Front

What is the first component that binds to the mRNA during translation?

Back

The small subunit of the ribosome binds to the mRNA message first.

Front

What is pinocytosis?

Back

Pinocytosis is the nonspecific internalization of dissolved substances outside the cell.

Front

Which part of the endomembrane system is responsible for protein synthesis?

Back

The rough endoplasmic reticulum (Rough ER) is the site for protein synthesis.

Front

What is the role of the nuclear envelope?

Back

The nuclear envelope surrounds the nucleus and regulates the passage of materials in and out of the nucleus.

Front

What is the function of ribosomes?

Back

Ribosomes are responsible for synthesizing proteins by translating mRNA.

Front

What is the difference between rough and smooth endoplasmic reticulum?

Back

Rough ER has ribosomes on its surface and is involved in protein synthesis, while smooth ER lacks ribosomes and is involved in lipid synthesis.

Front

What is exocytosis?

Back

Exocytosis is the process by which cells expel materials in vesicles.

Front

What is the role of the nucleolus?

Back

The nucleolus is responsible for producing ribosomal RNA (rRNA) and assembling ribosomes.
