Question

The genetic code is essentially the same for all organisms. From this, one can logically assume which of the following:

a) a gene from an organism can theoretically be expressed by any other organism

b) DNA was the first genetic material

c) the same codons in different organisms translate into different amino acids

d) different organisms have different types of amino acids

Answer 1

Correct answer: A). a) A gene from an organism can theoretically be expressed by any other organism

The protein synthesis information in the DNA is found to be contained by the three base sequences. Proteins are made from a chain of amino acids, which are directed by the codons present in the DNA.

Each codon is specified for the synthesis of only one amino acid. However, some amino acids are specified by more than one codon.

The correlation between the amino acid and codon is known as genetic code and is the same for every organism on the earth.
