What happens during transcription?
a new strand of DNA is made
a mRNA strand is made from a DNA template
an amino acid chain is made from a mRNA strand
What happens during translation?
a new strand of DNA is made
a mRNA strand is made from a DNA template

ribosome
What does an enzyme do?
slows down chemical reactions
speeds up chemical reactions
increases the temperature of the reaction
What happens to an enzyme when the temperature gets very hot?
The reaction slows down because the molecules are moving too slowly.
The reaction performs at the optimum speed.
The reaction does not occur because the enzyme has denatured.
