This is the enzyme that unwinds the DNA helix at the start of replication
Helicase

In one sentence, describe the processes of transcription and translation.
Transcription is using DNA to make a mRNA strand.
Translation used the codons on mRNA to construct the correct amino acid sequence to make a protein.

What is the complimentary DNA strand for the one below?
ACGGTA
TGCCAT
100
Describe genotype and phenotype.
Genotype is the genetic makeup
Phenotype is the physical features expressed by the genotype

How old is my son?

What is the very first step in DNA replication?
DNA has to unwind from a helix to a ladder structure - then the enzyme helicase can start to "unzip" the bases or break the hydrogen bonds
200
Transcribe the following DNA strand into an mRNA strand:
GGCATTA
CCGUAAU
200
What are the 3 parts of a nucleotide?
Phosphate, Sugar, Base
200
What is the very first step in the scientific method process after you have chosen a topic? For example, you want to study dolphins and their behavior in the ocean - what are you doing first?
Research!!
Research the species and behavior.

Where did I work before this?
Busch Gardens/USF
300
What is the product for DNA replication?
Two molecules of DNA made of the original old strand and a new strand
300
Where does transcription happen?
Nucleus
300
Why is DNA considered the universal code?
Because all living things have the same bases (ATGC) and therefore the same amino acids to make proteins.
300
What is a process that can add a new phenotype in a population?
Genetic Mutation
300
What kind of dog do I have?
Blue heeler
400
This is the term for the short fragments synthesized on the lagging strand during DNA replication
Okazaki fragments
400
Once mRNA has been constructed from DNA, what happens next for the mRNA?
The mRNA is transported out the nucleus and towards the ribosome for translation
400
What are the 3 types of RNA?
mRNA, tRNA, rRNA
400
What is the name of a mutation that does not change the expression of the trait?
Silent Mutation
The mutation may have a different codon but if the original codon and the mutated codon translate to the same amino acid than the same protein will be produced and no change in phenotype.

What's my favorite Harry Potter movie?
Goblet of Fire
500
What is the enzyme in step 2 that brings the correct bases when building the leading and lagging strands?
DNA Polymerase
500
Translate the following mRNA strand: GCC UAU UUU
Ala - Tyr - Phe
500
What are the 3 major differences between DNA & RNA?
1. Different sugars (deoxyribose vs ribose)
2. Double strand vs single strand
3. Thymine vs Uracil
500
What is one pro and one con for a farmer planting only genetically modified crops?
Pro - higher yield, resistance to pests (less use of pesticides)
Cons - Lowers genetic diversity

Who's my favorite Star Wars character?
Han Solo
