Biology - A1.2.1-A1.2.8

1) Passes information between generations

2) Code for protein production

1) Passes information between generations

2) Code for protein production

State the two primary functions of nucleic acids.

1) DNA : deoxyribonucleic acid

2) RNA : ribonucleic acid

State the two types of nucleic acids used in cells

Meaning:

All living organisms use DNAas the genetic material.

Implication:

The use of the genetic code across all forms of life is evidence of universal common ancestry of life. The sequences of DNA in cells can be analyzed and compared to determine evolutionary relationships between organisms. The more similar the sequence, the more closely related the organisms.

Outline the meaning and implication of DNA being the genetic material of all living organisms.

Some viruses use RNA as their genetic material. However, because virusesare not made of cells, they are not considered to be living.

State why RNA viruses do not falsify the claim that all living things use DNA as the genetic material.
