1. Monomers of DNA and RNA are nucleotides. What are the components of
   nucleotides?

sugar, nitrogenous base, phosphates

2. What is the overall shape of the DNA molecule?

• A double helix

3. What is meant by semiconservative replication? What is the result in the new
   DNA strands?

separation of two original strands, then they act as templates for the new strands. Nucleotides are base paired with the template for the new strands and chained up into a DNA molecule.
You end up with one new strand and one old strand.

4. . Know that information in a cell flows from DNA to RNA to Protein.

• DNA RNA Protein

5. What is transcription?

process that involves the transcribing of genetic info from DNA to RNA, RNA polymerase links nucleotides to form mRNA.

6. What is translation?

the process of assembling protein molecules from the information encoded in RNA

7. What is a codon? Anticodon? How many amino acids are there?

• Codon - 3 bases on an mRNA molecule that code for a specific amino acid
• Anticodon - 3 bases on a tRNA molecule that match up with the codons on the mRNA
• 1 amino acid

8. What is the difference between introns and exons?

• Exons are the DNA sequences that code for proteins
• Introns are involves but don't carry the genetic info that exons carry

9. What is a mutation?

a change in the DNA

10. What are phage or bacteriophage?

any one of a number of viruses that can infect bacteria.
