Unit 5 Review Quiz

What is a GENOME?

• Your complete DNA sequence spread out across your complete set of chromosomes

• A section of DNA that codes for a functional product

• A protein that reads mRNA to make other proteins

• The correspondence between certain codons and certain amino acids

Which of the following has to happen to the double-stranded DNA BEFORE information can be read from it?

• The relevant DNA must be replicated

• The relevant DNA must be translated

• The relevant DNA must be transcribed

• The relevant DNA must be unwound, unzipped

If (nearly) every cell in your body contains a complete genome, how (for example) are nerve cells different from muscle cells?

• Different cells delete different parts of the DNA

• Some cells eject some of their chromosomes

• Different cells unwind and read different parts of the genome

• Different cells mutate their DNA in different ways
