When a protein is synthesized on fixed ribosomes, it is threaded into the lumen of which structure(s)?

Biology

When a protein is synthesized on fixed ribosomes, it is threaded into the lumen of endoplasmic reticulum (ER).

Every eukaryotic cell has an endoplasmic reticulum (ER). The ER is arranged systematically into a web-like maze of radiating tubules and flattened sacs stretching all over the cytosol.

The tubules and sacs are all believed to interlink, so that the ER membrane forms an extended sheet bordering a single internal space. This highly complicated space is known as the ER lumen.

The ER traps selected proteins from the cytosol during their synthesis.

The two kinds of proteins include:-

  • transmembrane proteins, which are only partially moved across the ER membrane and are submerged in it, and
  • water-soluble proteins, which are completely transported across the ER membrane and are discharged into the ER lumen.

Why does more and more of the moon appear lit up as the moon passes from new moon to full moon?
Brrunno [24]

Full phase occurs when the Moon is on the opposite side of the Earth from the Sun and we see only the illuminated side. On that day it rises as the Sun is setting and sets and the Sun is rising. ... Waning Crescent phase occurs when the eastern edge of the Moon is lit but most of the visible surface is dark.

How would a tubal ligation or vasectomy influence meiosis in individuals who elected to have one of these operations
taurus [48]

Vasectomy and Tubal ligation are operations that have an effect on meiosis in individuals who have elected to have these operations in that it causes meiosis to stop.

A vasectomy or Tubal ligation are operations that are often performed as a method of birth control. A vasectomy is the male version of the operation and includes a procedure that negates the gametes or sex cells from reaching the sperm and being ejected from the body, thus preventing fertilization.

Tubal ligation is a similar process performed on women. The goal of this operation is the same as in the vasectomy, to stop the "egg cell" from being released and thus preventing it from being fertilized. Both procedures have been shown to cause meiotic arrest in individuals following the operation, In some cases, meiosis resumes after some time.

What happens after genetically modified plasmids are inserted into bacteria?
Oksanka [162]
After the genetically modified plasmids are inserted into bacteria; the bacteria make proteins from the inserted modified genes.

Explanations;
Plasmids are small, circular strands of DNA that are present in bacterial cells and are capable of self-replication. To add pieces of foreign DNA to bacteria, scientists first package the DNA of interest within the plasmid, and then induce the bacteria to take up the vector. This in turn makes the host bacterium a new, genetically modified organism. Once inside the bacteria, foreign proteins can be made within the bacteria, that is; if the introduced DNA is a gene that encodes a protein, then gene's protein product can be studied by expressing it in the bacteria.
