Question

It has been discovered that each species of organism has its own unique genetic code for synthesis of its proteins.

Select one:
True
False

Answer 1

The statement is false; the genetic code is universal across species suggesting a common origin, and is not unique to each species.

Step-by-step explanation:

The statement that each species of organism has its own unique genetic code for synthesis of its proteins is false. All living organisms share a universal genetic code, with only a few minor exceptions. This code dictates how sequences of DNA are translated into proteins. The conservation of codons across different species allows for the remarkable phenomenon where mRNA from one species can be translated into a protein within another species, such as horse globin being synthesized in a tulip cell. The universal nature of the genetic code suggests a common origin among all life on Earth.
