Which of the following statements about the nucleus is NOT true?
a. The nucleus stores 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 let's materials in and out.
bob please just answer the got dang question
The statement that is NOT true is a. The nucleus stores coded instructions for making the cell's proteins.
To find the answer to this question, we need to evaluate each statement and determine which one is not true.
a. The statement "The nucleus stores coded instructions for making the cell's proteins" is true. The nucleus contains DNA, which carries the genetic information and instructions for protein synthesis.
b. The statement "The nucleus usually contains a nucleolus region which is where ribosome assembly begins" is true. The nucleolus is a distinct region within the nucleus where ribosomal RNA (rRNA) is synthesized and assembled with proteins to form ribosomes.
c. The statement "The nucleus is the site of protein assembly" is not entirely accurate. While the nucleus is involved in certain steps of protein synthesis, including the transcription of DNA into messenger RNA (mRNA), the actual assembly of proteins occurs in the cytoplasm, specifically on ribosomes.
d. The statement "The nucleus is surrounded by a nuclear envelope that lets materials in and out" is true. The nuclear envelope consists of a double membrane with nuclear pores that regulate the passage of molecules between the nucleus and the cytoplasm.
Based on our evaluation, statement a is NOT true.
