QUESTION 5 Assuming mitosis is divided into prophase, prometaphase, metaphase, anaphase, and telophase, identify the events that take place in metaphase. The chromosomes move toward the equator by action of the kinetochore microtubules. The nucleolus disappears. Centrioles replicate. The nuclear envelope disappears. Microtubules attach to kinetochores. 000 All chromosomes are aligned on the metaphase plate. Sister chromatids split. Chromosomes condense. Spindle fibers form. Centrioles are migrating to opposite sides of the nucleus. QUESTION 6 Assuming mitosis is divided into prophase, prometaphase, metaphase, anaphase, and telophase, identify the events that take place in anaphase. Centrioles are migrating to opposite sides of the nucleus. Chromosomes decondense. The nuclear envelope reforms. The chromosomes move toward the equator by action of the kinetochore microtubules. All chromosomes are aligned on the metaphase plate. The nucleolus disappears. Sister chromatids split. Kinetochore microtubules shorten, pulling chromosomes to opposite poles. Spindle fibers form. Microtubules attach to kinetochores.

Proteins

We generally tend to think of proteins only from a dietary lens, as a component of what we eat. However, they are among the most important and abundant organic macromolecules in the human body, with diverse structures and functions. Every cell contains thousands and thousands of proteins, each with specific functions. Some help in the formation of cellular membrane or walls, some help the cell to move, others act as messages or signals and flow seamlessly from one cell to another, carrying information.  

Protein Expression

The method by which living organisms synthesize proteins and further modify and regulate them is called protein expression. Protein expression plays a significant role in several types of research and is highly utilized in molecular biology, biochemistry, and protein research laboratories.
