The formation of a new strand of DNA from existing DNA
The formation of a strand of mRNA from existing DNA
The formation of a protein using a strand of tRNA
The formation of a protein using a strand of mRNA
Select all of the following that apply to translation.
A new strand of protein is formed using mRNA as a template.
tRNA is used to bring free amino acids to a ribosome and attach them to the growing protein strand
mRNA Polymerase is required to split the strand of mRNA before translation can occur

Someone has a bacterial infection and is prescribed antibiotics. They take the first 5 days of a 7 day script, and feel much better. Which of the following should they choose to do?
Continue to take the antibiotics, as there may still be some lingering in their body that are mildly resistant to the medicine
Cease taking the antibiotics immediately, as taking antibiotics when you're feeling well can cause antibiotic resistance
Continue taking the medication but only take half doses, as it is no longer needed
Save the remaining antibiotics for later so that they can be used for any future bacterial infections.
A patient comes in to see a doctor with rhinovirus (a cold). They ask for antibiotics to help treat it. Should the doctor prescribe them, and why or why not?
Yes, because this will reduce the severity of the cold.
Yes, because this will limit the chance that they pass their virus onto someone else.
No, because they are likely to recover regardless of the medicine and antibiotics should be saved for serious infections
No, because antibiotics don't work on viral infections.
