Biology Questions

RNA - ribonucleic acid is a type of nucleic acid. The sugar contained in it is called Ribose.

A chromatid is one copy of a newly copied chromosome which is still joined to the original chromosome by a single centromere.

The two identical copies—each forming one half of the replicated chromosome are called chromatids.

Chromonema is the fibre-like structure in prophase in the primary stage of DNA condensation. In metaphase, they are called chromatids.

Herbivorous organisms are those that take for their food, plant parts like leaves raw in contrast to vegetarian, which means that plant products are taken raw or after being cooked.

Nucleoli are present during Interphase.

Chromosomes become visible during Prophase.

Centromeres divide and sister chromatids become full-fledged chromosomes during Anaphase.

Spindle fibers attach to kinetochores during Prometaphase.

Right ventricle (which pumps blood to the lungs), pulmonary artery (which carries blood to the lungs), and left atrium (which receives blood from the lungs) are involved directly in pulmonary circulation.

The process of copying dna is called Replication.

The marrow cavity is also known as the medullary cavity. It is the central cavity of bone shafts where adipose tissue is stored. It is lined with a thin, vascular membrane called endosteum.

The best example for somatic mutation would be cancer, familial cancer (which transmits through gametes to the next generation) are not so common while sporadic cancer is seen the most where body cells of a particular area goes through mutations for a number of years and becomes cancerous, but it is not transmitted to next generation.
