• translation

• transcription

• transformation

In DNA replication, a section of DNA with bases ATTC will line up with bases:

• GAAC

• AUUG

• ATTC

• TAAG

One difference between DNA and RNA is that

• DNA= 1 strand

• DNA contains ribose sugar

• DNA has a double strand

• RNA is more complex

A group of 3 letters representing an amino acid is called:

• nucleotide

• ribosome

• codon

• anticodon

Changes in the DNA sequence that affect genetic information are known as:

• replications

• transformations

• mutations

• prokaryotes

The bones of the forelimbs of the whale, the human and the bat are very similar. This indicates that they all may

• have descended from a common ancestor and have similar DNA

• belong to the same species

• Have to range great distances to eat

• Have identical DNA
