Put the following processes of protein synthesis in the correct order.
diamong [38]

<u>Correct sequential order for the following processes of protein synthesis are as follows:</u>

  • DNA strands unwind and separate
  • mRNA copies DNA according to complimentary base pairing  
  • mRNA leaves the nucleus
  • tRNA’s anticodons bring amino acids to the corresponding mRNA codons at the ribosomes
  • amino acids bind to each other making a polypeptide
  • a stop codon is reached, the newly formed a protein is released to go do its job for the cell

Option A --> B --> C --> E --> D -->F

<u>Explanation:</u>

Protein synthesis involves three major steps which are Replication of DNA, which is then transcribed and then translated to form protein, so the steps are Replication, Transcription and Translation.

Firstly, the DNA is a double stranded molecule which needs to be unwind as a replica where one of the strand becomes the template strand and transcription of strand occurs with mRNA.

mRNA thus leaves the nucleus and reaches cytoplasm where translation takes places and the tRNA provides specific anti codons to the mRNA codons and the amino acids are formed.

All amino acids bind to each other in order to make a polypeptide and hence the protein molecule newly formed is released to the cell.

Sidana [21]

macrophage are immune system cells that patrol the blood and body tissues. when a macrophage finds a foreign invader, the macrophage ingests (takes in) the foreign invader and then chemically digests (breaks down) that foreign invader. to perform this frequent chemical digestion, macrophage have more than the average body cell is

Macrophages are immune system cells that are vital to the development of non-specific defense mechanisms that provide the first line of defense against pathogens. These large immune cells are present in nearly all tissues and actively remove dead and damaged cells, bacteria, cancerous cells, and cellular debris from the body.

What is Macrophages?

Macrophages are specialized cells that hunt for, engulf, and kill bacteria and other dangerous organisms. They can also activate other cells by releasing substances known as cytokines, which present antigens to T cells and start an inflammatory response.

Blood monocytes that leave the bloodstream to differentiate in various organs give rise to macrophages. Each macrophage population exhibits significant variety, which most likely reflects the level of specialization necessary for each tissue's environment.
