Insertion into the RER membrane is cotranslational for TMPs, why is this necessary?

Biology
1 answer:
Zina [86]3 years ago
6 0

Answer:

Transmembrane  are inserted into the rough endoplasmic reticulum membrane  while they are still in their synthesis stage. They make there way to ER  with the help of the signal sequence already present in the synthesizing protein. The signal sequence stops the process of translation and directs the ribosome, carrying the unfinished protein to dock with ER.Translation than restarts when the signal sequence dock with the ER and it occurs in the ER membrane. This process is necessary because it allows the passage of transfer of protein to cross the lipid bilayer,  ER lumen facilitate protein folding and it rectifies the aberrant proteins and target them towards cytosol for destruction.

A man with blood group B marries with a woman with blood group AB and the daughter has blood group AB. Is this information enoug
disa [49]

Answer:

YES. This information is enough to assume that neither of the blood groups dominates over the other one.

Explanation:  

<u>Available data:</u>

  • A man with blood group B ----> Genotype IBIB or IBi
  • A woman with blood group AB ---> Genotype IAIB
  • Their daughter has blood group AB --> Genotype IAIB

The fact that the daughter´s genotype is IAIB tells us that she got the IA allele from the mother, who is IAIB, and the IB allele from his father, who is IB-.

  • If blood type B was dominant over A or AB, then the daughter should have Blood type B.
  • If blood type A was dominant over B or AB, then the daughter should have Blood type A.
  • Blood type AB tells us that both types are being expressed, A and B.

The fact that the daughter inherited one type of allele from each parent, but she is expressing the blood type AB, suggests that neither of the alleles dominates the other one. This is an example of co-dominance, where the heterozygote phenotype is an additive expression of both of the parents' genes.

This is enough information to assume that neither of the blood groups dominates over the other one.

Science has shown how information can only be gathered by the known laws of physics and chemisty.
8_murik_8 [283]
I would say the answer is false because they also used information of science to help make things like medicine and fungi and fossils, one of the main things science was used for was chemistry and physics to determine what things could kill humans in the world back in the day.


Hope this helps, Have a good day:), ~Nana!~
