Explain why red blood cells are unable to replace damaged proteins

Biology
1 answer:
Harman [31]2 years ago
3 0


The sole reason why red blood cells are unable to replace damaged proteins is that red blood cells lack DNA and cell organelles such as nucleus, ribosomes and mitochondria which are crucial for protein synthesis, assembly and repair. In other words they lack both the information and the machinery for making or repair of proteins.

Due to  lack of DNA and cell organelles, red blood cells cannot be able satisfy the central dogma which  summarizes synthesis of proteins as DNA → RNA → proteins.

DNA has the genetic information on how proteins should be made, RNA is responsible for transferring the information from DNA in the cell nucleus to the ribosomes  in the cytoplasm,  then translating or decoding  this information, which results in the making of  protein.

State three features of the intensive system of keeping animals
Schach [20]

The intensive system of keeping livestock is performed to cater the need of growing population, as people are declining day by day, who can afford to opt for their personal cattle. Thus also known as factory farming, where large amount of cattle are treated with full hygiene and facilities to produce more products like milk and milk products, egg, meat, etc. and with less cost. The basic features of intensive system are as follows:

  • The area required for such farming is small as compared to general, thus less land can fulfill the need of large population.
  • The method and technology used give employment to skilled workers and follow more rules and regulations to protect livestock from diseases.
  • Help in maintaining economical aspects in national level, by increasing production in bulk with comparatively less input.

Which phylum is a group of miscellaneous fungi that don’t fit into the other three categories? Zygomycotes Deuteromycotes Ascomy
DaniilM [7]

Answer:

Deuteromycotes

Explanation:

Kingdom Fungi consist of eukaryotic organisms grouped into 3 phyla, with one group that doesn't fit into any of the grouped three. Each group of fungi were classified into phylum based on their reproductive life cycle. The three phyla are Zygomycotes, Ascomycotes, Basidiomycotes.

Zygomycotes produce their spores by meiosis in a structure called Zygosporangium. Ascomycotes produce their spores via meiosis in ascus (sac-like). Basidiomycotes produce their own spores via meiosis in club-like basidium.

However, a fourth group exists that has no known sexual reproductive structure (meiospores), instead it is known to reproduce asexually via mitospores. This group is called DEUTEROMYCOTES or commonly known as FUNGI IMPERFECTI. It is a group of miscellaneous fungi that doesn't fit into the classification basis of the other three phyla.
