Which statement best explains how mutations change the shape of flu virus antigens, preventing the attachment of antibodies?

Biology
1 answer:
Setler79 [48]3 years ago
4 0

Answer:

A. Mutations change the nucleotide sequence of the gene, resulting in a different arrangement of amino acids.

Explanation:

Mutations alter the sequence of nucleotides in a molecule of DNA. DNA is used to create mRNA, which is used to create a chain of amino acids that make a protein. If the mutation changes the sequence of DNA, then the sequence of amino acids and the final protein will be different.

This can affect its structure and function. If the protein is a cell surface protein, and its structure is significantly altered, antibodies may no longer recognise and bind to the protein.

What do scientists know about fossils found in deeper layers of rock compared to
shusha [124]

Answer:

They know that layering, or bedding, is the most obvious feature of sedimentary rocks.  This Law of Superposition is fundamental to the interpretation of Earth history, because at any one location it indicates the relative ages of rock layers and the fossils in them. Layered rocks form when particles settle from water or air. That is kinda easy :D

An immunoglobulin (Ig) molecule, of any class, with regions symbolized as C or V, H or L , has a light chain made up of _______.
Nadusha1986 [10]

An immunoglobulin molecule of any class with regions symbolized as C or V, H or L, has a light chain made up of one C region and one V region.

The glycoproteins known as immunoglobulins (Ig), often known as antibodies, are created by plasma cells. A number of immunogens, including bacterial proteins, promote B cells' conversion to plasma cells. These cells, which make proteins, are involved in humoral immune reactions to bacteria, viruses, fungi, parasites, cellular antigens, chemicals, and synthetic compounds. Using a B-cell receptor, the immunogen or antigen adheres to the B cells' cell surface (BCR).

As a result, a signal is generated that directs the activation of transcription factors, leading to the manufacture of highly specific antibodies for the immunogen that initially activated the B cell. Furthermore, one B cell clone produces immunoglobulin (specificity). Two light chains and two heavy chains that alternate in a light-heavy-heavy-light pattern make up antibodies, also known as immunoglobulins. Therefore, choice A is the right response.
