Exam: GRE (Verbal)

Definition: The process where two gametes come together to create a single cell called a zygote.

Example: During fertilization, zygosis occurs when the sperm and egg unite.

Definition: The genetic condition of a zygote, which refers to whether it has identical or different alleles from its parents.

Example: The zygosity of the embryos was tested to determine their genetic similarity.

Definition: A type of spore that is formed when two similar reproductive cells join together, commonly found in certain algae and fungi. It often has a thick wall and can survive harsh conditions.

Example: The zygospore can remain dormant until conditions are favorable for growth.

Definition: A cell that is created when two reproductive cells join together, especially the fertilized egg before it starts to divide.

Example: After fertilization, the zygote begins to develop into an embryo.

Definition: A specific phase in the first stage of cell division where similar chromosomes pair up.

Example: During zygotene, the chromosomes align closely with their homologous partners.

Definition: Relating to the initial cell formed when a sperm cell fertilizes an egg cell.

Example: The zygotic stage is crucial for the development of the embryo.

Definition: A type of inactive protein that can be turned into an active enzyme by another enzyme or a specific process.

Example: The body produces zymogens that become active enzymes when needed for digestion.

Definition: A strip or band used in a laboratory to show the pattern of enzymes after they have been separated by a method called electrophoresis.

Example: The scientist analyzed the zymogram to identify the different enzymes present in the sample.

Definition: The study of the chemical processes involved in fermentation, especially in brewing and baking.

Example: Zymology is essential for understanding how yeast works in beer production.

Definition: A process of fermentation or an infectious disease, particularly one caused by a fungus.

Example: The zymosis in the bread dough caused it to rise and develop a unique flavor.
