Question

Which of the following statements best supports the claim that organisms share fundamental processes as a result of evolution? (A) All organisms that are introduced into new environments have the capacity to fill vacant ecological roles. (B) All organisms have the ability to utilize oxygen to harness energy from the chemical breakdown of organic compounds. (C) All organisms share a genetic code organized into triplet codons, making it possible for one organism to express a gene from another organism. (D) All organisms possess structures such as chloroplasts and mitochondria within their cells that reflect past symbiotic relationships

Answer 1

Answer:

C

Explanation:

All living organisms' cell are composed of genetic material in form of DNA. The DNA encodes the information needed for the production of useful products (proteins). The way in which the information is encoded is called the GENETIC CODE. It consists of all the triplet nucleotides in DNA or RNA that encodes an amino acid.

This genetic code is universal i.e. the same genetic code is employed by virtually all living organisms, as a codon does not encode another amino acid in another organism. It is universal that AUG specifies Methionine in all living organisms. This shows that all organism share a common evolutionary history.

Hence, it is possible for an organism to express a gene from another organism since the same genetic code will be used to read the information in the gene.
