Which location in cell is unlikely to contain ribosomes?

Which location in cell is unlikely to contain ribosomes?

The correct answer is option c because ribosomes are not found bound to the plasma membrane, membrane proteins are made in the endoplasmic reticulum…

Where in a plant cell can DNA and ribosomes be found?

The nucleus
The nucleus contains the cell ‘s DNA and directs the synthesis of ribosomes and proteins. Found within the nucleoplasm, the nucleolus is a condensed region of chromatin where ribosome synthesis occurs.

Do all cells have DNA and ribosomes?

All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. The plasma membrane, or cell membrane, is the phospholipid layer that surrounds the cell and protects it from the outside environment. Ribosomes are the non-membrane bound organelles where proteins are made, a process called protein synthesis.

What type of cell contains only ribosomes and DNA?

The Nucleus. One of the main differences between prokaryotic and eukaryotic cells is the nucleus. As previously discussed, prokaryotic cells lack an organized nucleus while eukaryotic cells contain membrane-bound nuclei (and organelles ) that house the cell’s DNA and direct the synthesis of ribosomes and proteins.

What is the difference between free and bound ribosomes and where is each type typically found?

Membrane-bound ribosomes are attached to a structure known as rough endoplasmic reticulum. Free and membrane-bound ribosomes produce different proteins. Whereas membrane-bound ribosomes produce proteins that are exported from the cell to be used elsewhere, free ribosomes produce proteins used inside the cell itself.

Where is the bacterial cell’s DNA found?

The DNA of bacterial cells is found loose in the cytoplasm. It is called chromosomal DNA and is not contained within a nucleus. Bacteria also have small, closed-circles of DNA called plasmids present in their cytoplasm.

Where are bound ribosomes?

the endoplasmic reticulum
Attached, or bound, ribosomes are found on the exterior of an organelle called the endoplasmic reticulum. Because the ribosomes give the organelle a lumpy appearance, the ribosome-containing portion is called the rough ER.

Where is a bacterial cell’s DNA found where is a bacterial cell’s DNA found ribosomes nucleus peroxisome nucleoid region capsule?

Bacteria lack a nucleus; their DNA is found in the nucleoid region.

Where are ribosomes located in the cell membrane?

1 It is located in two areas of cytoplasm. 2 Scattered in the cytoplasm. 3 Prokaryotes have 70S ribosomes while eukaryotes have 80S ribosomes. 4 Around 62% of ribosomes are comprised of RNA, while the rest is proteins. 5 The structure of free and bound ribosomes is similar and is associated with protein synthesis.

What are the two different types of ribosomes?

What are the two different types of ribosomes? The two different types of ribosomes include: 70 S-found in prokaryotic cells. 80 S-found in eukaryotic cells.

What is the difference between free-free and membrane-bound ribosomes?

Free Ribosomes: can move anywhere in the cytosol, but are excluded from the cell nucleus. Proteins that are formed are released into the cytosol and used within the cell. Membrane-bound Ribosomes: when a ribosome begins to synthesize proteins that are needed in some organelles, the ribosome making this protein can become “membrane-bound”.

What is the difference between prokaryotic and eukaryotic ribosomes?

Prokaryotes have 70S ribosomes while eukaryotes have 80S ribosomes. Around 62% of ribosomes are comprised of RNA, while the rest is proteins. The structure of free and bound ribosomes is similar and is associated with protein synthesis. The important ribosome function includes:
