$100 Question DNA is in the shape of a ________ _____
3
$100 Answer Double Helix
4
$200 Question ___________ and __________ were the 2 scientists to build a 3D model of DNA and received the credit for discovering its shape
5
$200 Answer Watson and Crick
6
$300 Question ________________ was a female scientist who used x-ray crystallography to take microscopic x-rays of DNA
7
$300 Answer Rosalind Franklin
8
$400 Question How did Rosalind Franklin’s work influence Watson and Crick’s 3D model for DNA? Explain
9
$400 Answer Her x-ray crystallography pictures strongly influenced the discovery of DNA’s shape.
10
Draw a picture of a DNA molecule on the board. Label A,T,G, and C
$500 Question Draw a picture of a DNA molecule on the board. Label A,T,G, and C

12
What does DNA replication mean?
$100 Question What does DNA replication mean?
13
When DNA is “reproducing” of making more copies of itself
$100 Answer When DNA is “reproducing” of making more copies of itself
14
Why is DNA replication called a semi-conservative process?
$200 Question Why is DNA replication called a semi-conservative process?
15
$200 Answer “partially saving” the original strand (half of the original molecule, 1 strand, is used in each of the new molecules)
16
What is the 1st step of DNA replication?
$300 Question What is the 1st step of DNA replication?
17
$300 Answer Unwinding
18
What are the 2nd and 3rd steps of DNA replication?
$400 Question What are the 2nd and 3rd steps of DNA replication?
19
$400 Answer Base Pairing Joining
20
$500 Question Using 2 different colored markers, draw DNA replication. (Original molecule and the 2 new molecules)
21
$500 Answer
22
How many strands does DNA have? RNA?
$100 Question How many strands does DNA have? RNA?
23
1 DNA molecule has 2 strands 1 RNA molecule has 1 strand
$100 Answer 1 DNA molecule has 2 strands 1 RNA molecule has 1 strand
24
$200 Question What nitrogenous bases does DNA have? RNA?
25
$200 Answer DNA= ATGC RNA= AUGC
26
$300 Question Why can’t DNA leave the nucleus?
27
$300 Answer It’s too big; double-stranded Won’t fit through nuclear pores
28
$400 Question Explain why RNA needs to copy itself from DNA
29
$400 Answer RNA is single stranded, can fit through pores Can carry copied information to ribosomes so they can make proteins
30
$500 Question If RNA is only single stranded, how can it carry all of the information from DNA (double-stranded) to the ribosome?
31
$500 Answer
32
$100 Question Identify DNA and RNA in the following picture
33
$100 Answer
34
$200 Question Identify Transcription in the following picture
35
$200 Answer
36
$300 Question Identify Translation in the following picture
37
$300 Answer
38
$400 Question Identify the ribosome in the following picture
39
$400 Answer
40
$500 Question Identify the protein in the following picture
41
$500 Answer
42
$100 Question What 2 types of mutations may cause a FRAMESHIFT mutation, meaning the DNA sequence if shifted forwards or backwards?
43
Deletion and Insertion
$100 Answer Deletion and Insertion
44
What type of mutation is this? Original: TAC AGG ACT
$200 Question What type of mutation is this? Original: TAC AGG ACT Mutated: TCA GGA CT
45
$200 Answer Deletion of the “A” in first codon
46
$300 Question What amino acid will be made from the DNA codon ACC?
47
$300 Answer
48
Name the 5 types of possible mutations, and what happens in each type
$400 Question Name the 5 types of possible mutations, and what happens in each type
49
$400 Answer DELETION (base is lost/deleted)
INSERTION (extra base is added) SUBSTITUTION (one base is substituted for another) --- If a substitution changes the amino acid, it’s called a MISSENSE mutation --- If a substitution does not change the amino acid, it’s called a SILENT mutation --- If a substitution changes the amino acid to a “stop,” it’s called a NONSENSE mutation
50
$500 Question Mutated DNA: TAC ATC TTG ACT The mutated base (T) was made in place of an A. Come to the board and write the mRNA sequence, and the amino acids made. What type of mutation is this?
