Which cell component will show an increase in radioactivity?
Which cell component will show an increase in radioactivity?
The endoplasmic reticulum is responsible for trafficking (some) proteins to certain locations in the cell. These proteins which were synthesized with the radioactive amino acids would thus show increased radioactivity of the endoplasmic reticulum.
In which organelle would radioactive amino acids be detected first?
the rough ER
After a brief exposure of pancreatic acinar cells to radioactive amino acids, newly synthesized proteins were detected in the rough ER, which was therefore identified as the site of synthesis of proteins destined for secretion.
What happens to a protein made on a ribosome that is connected to the rough ER?
Rough ER. The rough endoplasmic reticulum (rough ER) gets its name from the bumpy ribosomes attached to its cytoplasmic surface. As these ribosomes make proteins, they feed the newly forming protein chains into the lumen. Some are transferred fully into the ER and float inside, while others are anchored in the membrane …
What happens interphase?
During interphase, the cell grows and makes a copy of its DNA. During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells.
Which organelle modifies and packages vesicles that are routed within the cell?
3)Golgi apparatus modifies, sorts and packages protein into secretory vesicle.
Which of the following clues would tell you if a cell is prokaryotic or eukaryotic?
The correct option is c. whether or not the cell is partitioned by internal membranes. Internal membranes are one of the characteristic features of eukaryotic cells that distinguish them from prokaryotic cells.
What organelles do ribosomes interact with?
The protein synthesis at the ribosome can take place in the cytoplasm or at an organelle called the endoplasmic reticulum. In organisms with an organized nucleus, known as eukaryotes, the endoplasmic reticulum and ribosomes play important roles in the synthesis of proteins.
What causes the ribosomes to attach to the rough endoplasmic reticulum?
It is the presence of Translocons and Signal Recognition Protein Receptor on the surface of the Endoplasmic reticulum which makes the ribosomes to get attached to the Endoplasmic reticulum.
Why does rough endoplasmic reticulum appear rough under a microscope?
Rough Endoplasmic reticulum looks rough when observed under the microscope as it has presence of ribosomes on its outer surface which help it in the protein synthesis… Hope this helps!
