What is DNA Replication?
Creating another strand of DNA from an already existing strand.
What are the two types of bonds in the DNA structure AND where are they located?
Covalent Bond - Outside
Hydrogen Bond - Inside (holds two bases together)
What has the directions for making a protein?
DNA
What type of mutation occurred?
Normal Strand:
CGA-UAA-CCC-AAC
Mutated Strand:
CGA-UUA-CCC-AAA
Substitution Mutation - Missense
What do ribosomes do?
Create proteins
Replicate the following:
ATGGGCTATTCCGAT
TACCCGATAAGGCTA
What are THREE differences between DNA and RNA?
DNA is double stranded and RNA is single stranded.
DNA bases are A, T, G, C and RNA bases are A, U, G, C.
The sugar in DNA is deoxyribose and the sugar in RNA in ribose.
What is the codon AND amino acid that codes for START.
Amino Acid - Met
What is the mutation that can lead to Trisomy or Monosomy?
Nondisjunction (Chromosomal Mutation)
What is it called when you splice/combine one type of DNA with a different type of DNA?
Recombinant DNA
There are two enzymes involved in DNA Replication. What is one of them and what does it do?
Helicase - "unzips" the DNA strands
DNA Polymerase - creates the new DNA strand
What are the basic units of DNA?
Nucleotides
There are 20 codons. How many amino acids will this result in?
20
What type of mutation occurred?
Normal Strand:
AUG-GCC-UUA-CAG
Mutated Strand:
AUG-GCA-UUA-CAG
Substitution Mutation - Silent
What does GMO stand for and give an example.
Genetically Modified Organism
Examples vary
What two macromolecules can you relate to this unit AND HOW?
1. Nucleic Acids - Monomer is a nucleotide and examples are DNA and RNA. Also, nucleic acids have carbon, oxygen, nitrogen, and PHOSPHORUS.
2. Proteins - Protein synthesis :)
What are the actual names of DNA and RNA?
Deoxyribonucleic acid AND Ribonucleic acid
What amino acids does this strand code for:
TAGCATGAC
Ile-Val-Leu
What type of mutation occurred?

Chromosomal Mutation - Duplication
There are 13 codons. How many bases are there?
39
What STAGE during Cell Division does DNA replication take place?
S Stage - Interphase
What are the parts of a nucleotide?
Sugar, Phosphate, and Nitrogen Base
Create a DNA (DNA!!!!) strand that could code for the following amino acid pattern:
Arg-Asp-Ser-Leu-STOP
Answers vary
Insertion and Deletion are a type of GENE mutation. What mutation are they referred to as?
Frameshift Mutations
Draw a nucleotide on the board AND label it.
