What else can I help you with?
What has a series of membranes studded with ribosomes following organelles?
The rough endoplasmic reticulum is located close to or surrounding the nuclear envelope. This is studded with ribosomes.
Holes in the nuclear membrane where mRNA leaves to move to the ribosome?
The nuclear pores in the nuclear membrane allow mRNA to exit the nucleus and move to the ribosomes in the cytoplasm for protein synthesis. These pores regulate the passage of molecules like mRNA by actively transporting them through the nuclear envelope.
Explain how the nucleolus contributes to protein synthesis?
The nucleolus is responsible for assembling ribosomes, which are the cellular machinery for protein synthesis. It synthesizes and exports ribosomal RNA (rRNA) and combines it with proteins to form ribosomal subunits. These ribosomal subunits then come together in the cytoplasm to create functional ribosomes that participate in protein synthesis.
The fact that the outer membrane of the nuclear envelope has bound ribosomes allows one to most reliably conclude that?
at least some of the proteins that function in the nuclear envelope are made by the ribosomes on the nuclear envelope. I promise this is the right answer, i did it on masteringbio two seconds ago.. Good Luck :-)
How does mRNA get out of the nucleus and into the cytoplasm for protein synthesis?
mRNA is transported out of the nucleus through nuclear pores in a process called mRNA export. Once in the cytoplasm, the mRNA binds to ribosomes where protein synthesis occurs.
Does the nuclear envelope have ribosomes?
No. It does not. The Rough Endoplasmic Reticulum does.

Type of RNA small enough to fit through the pores of the nuclear envelope?
The type of RNA that is small enough to fit through the pores of the nuclear envelope is messenger RNA (mRNA). mRNA carries the genetic information from DNA to the ribosomes in the cytoplasm, where it is used as a template for protein synthesis.
Is it true or false that ribosomes are permeable to the nuclear membrane?
False. Ribosomes are not permeable to the nuclear membrane. They are synthesized in the nucleolus of the nucleus and then transported out through nuclear pores to the cytoplasm where they function in protein synthesis.

What job does the nucleus membrane have?
The nuclear membrane, or more often called nuclear envelope, isolates a eukaryotic cell's chromatin(DNA) from the rest of the cytoplasm. The nuclear envelope is believed to have formed from the infolding of the cell membrane(basically the same process that also formed the endoplasmic reticulum). Unlike the cell membrane the nuclear envelope contains pores which are essential for the movement of mRNA from the nucleus out to the cytoplasm where ribosomes are located so protein synthesis can be undertaken.
What is a network of sacs and tubules extending off the nuclear envelope where proteins and lipids are produced?
The endoplasmic reticulum (ER) is a network of sacs and tubules extending off the nuclear envelope where proteins and lipids are produced. It is divided into rough ER, studded with ribosomes for protein synthesis, and smooth ER, which is involved in lipid metabolism and detoxification.

mRNA is transported out of the nucleus through nuclear pores in a process called mRNA export. Once in the cytoplasm, the mRNA binds to ribosomes where protein synthesis occurs.
The RNA type that diffuses through the nuclear pores to direct the assembly or synthesis of new protein molecules at the ribosomes in the cytoplasm is what?
Messenger RNA (mRNA) is the type of RNA that carries genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm, where protein synthesis occurs. It is transcribed in the nucleus and then travels through the nuclear pores to direct the assembly of new proteins at the ribosomes.
Organelles at which amino acids are hooked together to make protiens?
Its the tRNA molecule which assembles amino acids together inside of the ribosome. So technically, you could say that it is the ribosome which assembles them. This is done through a process called 'protein synthesis', more specifically at the translation level.
