In the life-cycle of the malaria parasite plasmodium, where does fertilization and formation of the zygote occur?.
daser333 [38]

Fertilization and formation of the zygote occur Within the body of mosquito.

Zygote, from the Ancient Greek (zygtós), "attached, yoked," from (zygoun), "to join, to yoke," A fertilization between two gametes produces  a eukaryotic cell. The genome of a zygote, which consists of the DNA from each gamete, is what makes up a new individual creature and holds all of its genetic material.

The zygote is the first developmental stage in animals with many cells. When an egg cell and sperm cell unite to produce a new, distinct organism, a zygote is created in humans and the majority of other anisogamous species. With the aid of mitosis, the zygote can divide asexually in single-celled organisms to create identical progeny. The chloroplast DNA (cpDNA) of a Chlamydomonas zygote is inherited uniparentally from the parent with the mt+ mating type; as a result, such cells are typically uncommon. The mapping of chloroplast genetics through recombination was made possible by these uncommon biparental zygotes.

Disulfide bonds are important in determining and stabilizing protein structure. Which amino acid, if mutated, will affect the fo
elixir [45]

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.

konstantin123 [22]

Answer;

-Enzymes

Enzymes are class of proteins, they make metabolic reactions proceed much faster than they would have on their own.

Explanation;

-Proteins are biological macromolecules that are diverse in shape size and function. Enzymes are biological molecules (proteins) that act as catalysts and help complex reactions occur everywhere in life. They are biological catalysts.

All enzymes are proteins by definition. But not all biomolecular catalysts are proteins. Most enzymes are proteins, although a few are catalytic RNA molecules.
