Question

Two scientists are both studying RNA. One scientist is studying RNA in mice and the other is studying RNA in E. coli bacteria. Which of the following best describes how each scientist would use a genetic code?

A. Both scientists would use the same genetic code because all organisms have RNA.
B. Both scientists would use the same genetic code because in all organisms the code is read three bases at a time and in the same direction.
C. The scientist studying mice would use the genetic code for mice and the scientist studying E. coli would use the genetic code for E. coli because mice are more complex multicellular organisms.
D. The scientist studying mice would use the genetic code for eukaryotes and the scientist studying E. coli would use the genetic code for prokaryotes because they each have different types of chromosomes.

Answer 1

B. Both scientists would use the same genetic code because in all organisms the code is read three bases at a time and in the same direction.

Step-by-step explanation:

The genetic code, which refers to how a gene is used to synthesize a protein in cells, is said to be NEARLY UNIVERSAL for all living organisms. This characteristics means that the same genetic code is used by almost every living organism.

According to this question, two different scientists are studying RNA in mice and E.coli bacteria respectively. Based on the characteristics of the genetic code explained above, each scientist will use the same genetic code for the two organisms because in all organisms the code is read three bases at a time called CODON and in the same direction.
