Process of mRNA and Nucleus

These flashcards cover key concepts about the processes involving mRNA and the nucleus as discussed in the lecture.

What is the primary function of mRNA in cells?

To carry genetic information from DNA to the ribosomes for protein synthesis.

What organelles are involved in the synthesis of proteins?

Ribosomes, rough endoplasmic reticulum, and Golgi apparatus.

What characterizes eukaryotic cells?

They have a nucleus and membrane-bound organelles.

What is the structure that separates the nucleus from the cytoplasm?

Nuclear membrane (nuclear envelope).

What is the role of ribosomes in protein synthesis?

They translate mRNA into amino acids to form proteins.

What are lysosomes responsible for in a cell?

Breaking down waste materials and cellular debris.

How is mRNA transported outside the nucleus?

It exits through nuclear pores in the nuclear membrane.

What distinguishes prokaryotic cells from eukaryotic cells?

Prokaryotic cells lack a nucleus and membrane-bound organelles.

What is the function of the endoplasmic reticulum?

To synthesize proteins and lipids, and detoxify certain chemicals.

What is the significance of the Golgi apparatus?

It modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

What is the function of mitochondria in cells?

To produce ATP through cellular respiration.

What role do chloroplasts play in plant cells?

They convert light energy into chemical energy through photosynthesis.
