The information in DNA is written according to the genetic code and carried by the -

• sequence of nitrogen bases/nucleotides

• direction of the phosphate groups

• hydrogen bonds between nitrogen bases

• enzymes which unwind the double helix

The genetic code describes the way that information is coded in DNA. This code is -

• unique to organisms like a fingerprint

• similar between closely related organisms

• determined by organism’s environment

• the same among all living organisms

What do we call the shape a DNA molecule takes?

• double-stranded

• double helix

• sugar-phosphate backbone

• pentagon

What are the names of the large structures of DNA which are used to package the genetic information within cells?

• enzymes

• ribosomes

• chromosomes

• vitamins

The genetic code seems to suggest that all organisms are related. This conclusion is based on the fact that –

• all living things have unique coding systems

• each species has some form of a code

• every living thing uses the same code

• living things pass DNA to offspring
