Answer:
Ecological importance
Healthy ecosystems depend on plant and animal species as their foundations. When a species becomes endangered, it is a sign that the ecosystem is slowly falling apart. Each species that is lost triggers the loss of other species within its ecosystem
A universal genetic code allows "the processes of transcription and translation to produce the same proteins in all species."
To say that the genetic code is universal it means that it is read/interpreted in the same exact way in all cells. This is that the same group of three nucleotides, a codon, will always translate into the same amino acid in any cell leading to the formation of the same protein, or at least a protein with same amino acids when first formed.
These microbial infections that are acquired by hospital patients as they are being used as the compromised host are the nosocomial infections. These type of infections are primarily caused by bacterial pathogens entering the patient's body and mainly causes urinary tract infection, pneumonia, and other illnesses.
Answer and explanation:
Antibodies are structures made of four polypeptides, <em><u>two light (L) chains and two heavy (H) chains that join together and form a molecule shaped like a "Y"</u></em>. This structure is possible thanks to the <u>disulfide bonds</u> that bind light chains and heavy chains together. While the stem of the Y is constant and doesn't change ("<em>constant region</em>"), the tips of the Y, composed of 110-130 amino acids and called "<em>the variable region</em>", vary greatly among the different antibodies and are responsible for the high specificity of these molecules.
<u>This is why we could say that the primary structure of this protein is given by disulfide bridges that twist the antibody and allow it to bind to a protein from the flu virus.</u>
