1. What are anabolic steroids?
(1) Definition and structure of anabolic steroids
Anabolic steroids - or more precisely, anabolic-androgenic steroids are synthetic derivatives of testosterone.
The effects of anabolic-androgenic steroids mimic those of testosterone. Natually synthesized hormones, such as testosterone, are types of lipids. they have a four-ring carbon skeleton and are synthe
prokaryotic cells, and they have many more genes. The eukaryotic chromosome has a much more complex structure than prokaryotic chromosome. Well before a eukaryotic cell begins to divide, it duplicates all of its chromosomes. The result is that each chromosome now consist of two copies called sister chromatids, which contain identical copies of the DNA molecule. once seperated from its sister,

② controlling cell numbers, removing abnormal, misplaced, non-functional or harmful cell
③ producing differentiated cells without organelles
