Circulating plasma antibodies recognize a what as self and thus do not initiate an immune response

Biology
1 answer:
rosijanka [135]2 years ago
4 0

The right answer is a surface glycoprotein.

The antigens of the non-self correspond to any substance foreign to the organism, identified as such by the immune system of our organism which produces an energetic defense. Antigens are usually proteins (more specifically glycoproteins) contained in cells or foreign bodies (red blood cells transfused, organs transplanted, bacteria, viruses), or present in the environment (pollen, mite droppings, cat hair , etc.).

Our body has its own antigens that allow it to have a "specific identity card" and will be recognized as foreign by other organizations. They are called "self antigens".

Explain how he interaction between mRNA codons and tRNA codons anticodons codes for a specific amino acid
Julli [10]
<span>The interactions between the mRNA codons and the tRNA anticodons  codes for a specific amino acid is by, it is the job of the tRNA to start working after the mRNA has able to have its own complementary copy. The mRNA will undergo to the nucleus and will move out, in order to go the rrna. The three nucleotides codes the specific amino acid of the trna. The trna and the mrna will be matched, it will now release the amino acid in the trna that wil form a peptide bond. When the mrna is able to be decoded to form an amino acid, it will now have the ability to break and make proteins in different structures.</span>

How do ldl and hdl differ structurally and functionally?
ZanzabumX [31]

The main structural difference between LDL and HDL is their compositions. Approximately 50% of the weight of an LDL particle is cholesterol and only 25% is protein. High-density lipoprotein particles, on the other hand, consist of 20% percent cholesterol by weight and 50% protein.

if the velocity of a vehicle starting from rest reaches 5m/2s in 2seconds, is the velocity of the vehicle uniform ?explain.​
Vanyuwa [196]

Explanation:

Avg speed × total times = total distance

20×25=500
