The organelle that contains instructions for making proteins is the nucleus. Within the nucleus, DNA is transcribed into messenger RNA (mRNA), which is then translated into proteins by ribosomes in the cytoplasm.
mRNA does not enter the nucleus. It is transcribed from DNA inside the nucleus and then exits the nucleus to carry genetic information to the ribosomes in the cytoplasm for protein synthesis.
Nuclear pores are small openings in the nuclear envelope that regulate the passage of molecules such as proteins and RNAs into and out of the nucleus. This selective permeability is crucial for maintaining the integrity and function of the nucleus.
no!
Proteins are synthesized in the ribosomes, not in the Golgi complex or the nucleus. The nucleus contains the genetic information (DNA) needed to make proteins, which is transcribed into messenger RNA (mRNA) molecules that carry the instructions to the ribosomes. The Golgi complex modifies, sorts, and packages proteins synthesized in the endoplasmic reticulum before they are sent to their final destination within or outside the cell.
Materials enter and leave the nucleus through nuclear pore complexes in the nuclear envelope. Large molecules, such as proteins and RNA, are actively transported into and out of the nucleus through these pores using specific transport proteins. Small molecules, like ions and small proteins, can freely diffuse through the pores.
Materials enter and leave the nucleus through openings called nuclear pores. These pores regulate the movement of molecules, such as RNA and proteins, between the nucleus and the cytoplasm. They allow for communication and transportation of essential components for cellular functions.
No, proteins with a nuclear localization signal require energy to actively transport through the nuclear pore complex into the nucleus. They are not able to enter the nucleus passively. The binding and translocation through the nuclear pore are facilitated by specific transport receptors and require energy in the form of GTP hydrolysis.
Proteins are made using DNA. DNA is stored in nucleus
The Nucleus Envelope.
allows molecular proteins to enter through nuclear pores that permeate the double membrane. different than mitochondrial and chloroplast membranes because it allows whole proteins to enter. each membrane has a different molecular composition, signalling that there are two functions.
Some of the things inside the nucleus where proteins are made are ribosomes, nucleoplasm, and nuclear pore.

Ribosomes are not generally found inside the nucleus as they are primarily responsible for protein synthesis in the cytoplasm. While some ribosomal RNA (rRNA) components are synthesized in the nucleus, these do not become full ribosomes within the nucleus; rather, they combine with proteins to form ribosomes in the cytoplasm.
Why is this a problem if proteins are made in the ribosomes and how does the nucleus solve it
The nucleus directs the cell to make proteins.
