This selelction goes against the average individual in a population.
Answer:
The correct answer is "In order to create a synthetic life form it would be necessary to know the function of every gene and include them in the organism".
Explanation:
The most common approach of studies using recombinant DNA technology is to insert a desirable gene from one organism into a host organism. This approach is much more feasible that creating a synthetic life form because, in order to create a synthetic life form, it would be necessary to know the function of every gene and include them in the organism. Even though the whole DNA sequence of many organisms is known (including humans), the function of the entire sequences of the genome is yet to be understood.

Explanation:
Steroids are naturally occurring as sterols, adrenal, sex hormones, some vitamins and make up most drugs as synthetic steroids.
Types Of Steroids and Their Functions
1. Anabolic Steroids
-increase muscle mass
-promote cell growth and division
-testosterone( natural anabolic steroid) is used in sperm production, development of male reproductive organs and emergence of male secondary sexual characteristics.
-stimulates bone and muscle growth.
2. Sex Hormones
-produced by adrenal cortex
-aid in development of gametes
-prepare females for pregnancy, menstruation
OTHER
-enable longer athletic sessions
-increase protein synthesis
-Anti-inflammatory steroids can reduce swelling, pain and other manifestations of inflammation
