Answer:
c. cysteine
Explanation:
Cysteine is a non essential amino acid. It contains sulfur in form of thiol group. A disulfide bond or bridge is formed between two thiol groups. It is represented as S-S. It is formed by oxidation of two cysteine molecules. The resultant disulfide bond is called as cystine which connects two polypeptide chains.
Cysteine is the only amino acid capable of forming disulfide bridge. It stabilizes protein's globular structure and plays an important role in protein folding and stability. Cysteine is required for protein synthesis, metabolic processes and detoxification. It is the part of beta-keratin which is the main protein in nails, hair and skin. If cysteine is mutated, formation of disulfide bond will be affected.
Answer:
D. Allosteric activator
Explanation:
In an enzyme, the allosteric site is a site/motif different from the active site, (i.e., the site with catalytic activity) which is able to interact with regulatory effector molecules in order to activate or inhibit enzymatic activity by influencing the tridimensional (3D) structure of the enzyme. An allosteric activator is an effector molecule with the ability to bind to a specific enzyme at a different site than the active site, thereby modifying the shape of the enzyme and increasing the affinity of this enzyme for its substrate. Moreover, Adenosine monophosphate (AMP) is a nucleotide composed of a phosphate group, a sugar ribose, and an Adenine (A) base. This effector molecule (AMP) has shown to allosterically stimulate diverse enzymes in physiological conditions (e.g., AMP-activated protein kinase).
Answer:
25 percent.
Explanation:
The mom and dad mostly have the dominant gene E which is green but the dad has one e which is blue so I believe there is a 25 percent chance the child will have blue eyes.
Answer:
The HYPOTHESIS
Explanation:
In an experiment, the formulation of the hypothesis is a critical part of the scientific method. The hypothesis is testable explanation given after making an observation in an experiment. In other words, an hypothesis is a predictive statement given that is subject to testing via experimentation.
The essence of formulating an hypothesis is to relate the effect of a possible solution on an observed problem. The "hypothesis" section of a laboratory report is usually identified by the use of an IF and THEN phrases in the statement. IF represents the cause, while THEN represents the effect. For example, a hypothesis can read; If plants are placed under white light (cause), then they will grow faster in height (effect).
