DNA STRUCTURE
1. What role did Rosalyn Franklin play in our understanding of DNA’s structure? She discovered the double-helix position of the DNA.
2. What role did James Watson & Francis Crick play in our understanding of DNA’s structure? They discovered the 3D structure.
3. What type of macromolecular is DNA? Nucleic acid
4. What are the monomers of DNA? Nucleotides
5. What is the structure of a nucleotide? Draw It. A nucleotide consists of a

What molecule is read and what molecule is made in transcription? mRNA and rRNA.
7. What is a promoter? A sequence of nitrogenous bases in DNA that signals the enzyme complex "DNA-polymerase" to begin unwinding the gene to transcribe it.
8. What are introns? Exons? Exons are the parts of the gene that will represent the codons for creating the protein. Introns lie between exons,and act as wasteful DNA, as they are cut out before the gene is translated
9. What molecule is read and what molecule is made in translation? Exons are made in translation while introns are read.
10. What is the job of RNA polymerase? RNA Polymerase uses a DNA template to make a complimentary copy of RNA
11 . What is a codon? An anticodon? A codon is a three-base sequence (three nitrogen bases in a row) on mRNA. An anticodon is a three-base sequence on tRNA. It matches the codon
-Be able to use an codon table to determine the amino acid sequence if given an mRNA message.-
12. What happens in TRANSLATION? The cell uses information from messenger RNA to produce proteins. How do the 3 kinds of RNA work together to complete this process?
13. What are the monomers of proteins? What bond holds the monomers of a protein together? Proteins are chains of amino acids. The primary structure consists of which amino acids there are, and their sequence.
14. What is the structure of an amino acid? Draw It. An amino acid contains a central carbon bonded to a carboxyl group, an amino group, an
