Which of the following statements about the nucleus is not true?
a. the nucleus stores the coded instructions for making the cell’s proteins.
b. the nucleus usually contains a nucleolus region which is where ribosome assembly begins.
c. the nucleus is the site of protein assembly.
d. the nucleus is surrounded by a nuclear envelope that lets materials in and out.

answer;

the nucleus is the cite of protein assembly

explanation;

-the nucleus is an organelle found in eukaryotic cells. inside its fully-enclosed nuclear membrane, it contains the majority of the cell's genetic material. this material is organized as dna molecules, along with a variety of proteins, to form chromosomes. it governs gene expression and facilitates dna replication during the cell cycle.

-it coordinates the cell's activities, which include growth, intermediary metabolism, protein synthesis, and reproduction (cell division).

-protein assembly takes place in the cytoplasm in the structures called ribosomes found out-side the nucleus.

interphase   is the cell cycle stage in which the cell acquires nutrients, creates and uses proteins and other molecules and starts the process of cell division by replicating the dna. it is the longest stage in the eukaryote cell cycle.

the following   can go wrong during interphase:   a base pair could be mismatched during the duplication process causing a mutation.   correct answer: c

explanation:
