Which of the following best describes the effect of a greater number of cysteine amino acids on the stability of the proteins

Answers

Answer:

The correct answer is -

The change leads to increased protein stability because of an increased number of S-S bonds in the tertiary structure of the proteins.

Explanation:

Cysteine is a special amino acid due to having a free thiol group that can react and forms a sulfur-sulfur bond with another thiol of another cysteine in a protein structure.

These disulfide bonds can stabilize proteins if formed properly and promote stability to the tertiary structure of the proteins. The more the cysteine, the greater the number of thiols, and the greater the s-s bond in the proteins and more stability to the protein.

III. The basic units of all living things are organelles.

Answers

Answer:

the statement that is correct is the lll.

The statement which is supported by the principles of cell theory is as follows:

Genetic information is passed from a parent cell to a daughter cell.

Thus, the correct option for this question is B.

What is Cell theory?

Cell theory was proposed by two famous scientists known as M.J. Schleiden and T. Schwann. The principles of cell theory are as follows:

All living organisms whether plants or animals are made up of cells.A cell is the smallest unit of all living organisms.A Cell is the structural and functional unit of organisms.

This cell theory was further refined by German biologist Rudolf Virchow in 1855. According to him, all cells are arising from a pre-existing cell. A Virus is an exception to the cell theory.

Originally, none of the given statements exactly matches any one of the three principles of cell theory. But the second option reached approximately near around it.

Therefore, the correct option for this question is B.

The phenotype of an organism ?
- represents its genetic composition.
- occurs only in dominant pure organisms.
- cannot be seen.
- reflects all the traits that are actually expressed
HELP PLEASE

Answers

Phenotype are traits what is actually expressed

Answer:

The phenotype of an organism reflects all the traits that are actually expressed.

Explanation:

Phenotype refers to the visible or evidentiable characteristics that depend on the genotype, which is stored in the DNA. Phenotypic expression, mainly determined by genes, also depends on the influence of the environment on the individual.

Although the phenotype expresses characteristics such as skin, eye and hair color, height or shape of the nose, some characteristics are not entirely visible, such as specific functions or synthesized proteins.

The other options are not correct because:

Represents its genetic composition: this is genotype. Phenotype occurs in all individuals, both dominant and recessive.Many phenotypical characteristics are visible.

How does the structure of an amino acid relate to its function in cellular processes?

Answers

Explanation:

Protein function is directly related to the structure of that protein. A protein's specific shape determines its function. If the three-dimensional structure of the protein is altered because of a change in the structure of the amino acids, the protein becomes denatured and does not perform its function as expected.☺
Search Results Featured snippet from the web
A protein's shape determines its function. Proteins are composed of amino acid subunits that form polypeptide chains. Enzymes catalyze biochemical reactions by speeding up chemical reactions, and can either break down their substrate or build larger molecules from their substrate. ( hope this helped
