• Transcription

Two strands of DNA twisted around each other in a spiral

• Double helix
• Replication
• DNA polymerase
• Transcription

The process of copying DNA prior to cell division

• Codon

A change in an organism’s genetic code, caused by a mistake or damage to its DNA

• mRNA
• Mutation
• Translation
• Codon

RNA that carries instructions from DNA in the nucleus to a ribosome

• mRNA

• Translation
• Codon

When a series of mRNA codons are converted into a series of amino acids to make a protein

This is a model of DNA. Which part of DNA contains genetic information?

• the order of different nitrogen bases
• the order of sugars and phosphates
• the total number of base pairs
• the tightness of the coils

The backbone of DNA (or the side of the ladder) is made up of repeating units of the same chemicals over and over again. What are these chemicals?

• phosphates and deoxyribose sugars bonded together
• 2 bases bonded together
• phosphates and bases bonded together
• several phosphates bonded together
