Who performed the first major experiment that led to the discovery of DNA as the genetic material?
What is Fredrick Griffith
100
What is a Semiconservative Replication?
What is when the Parental strands of DNA separate, serve as templates, and produce DNA molecules that have one strand of parental DNA and one strand of new DNA.
100
What are the three types of RNA?
What is mRNA, tRNA and rRNA.
100
Also known as the section of DNA that contains the genes for the proteins needed for a specific metabolic pathway.
What is Operon
100
Other than Griffth...Who were the other three scientists that led to the discovery of DNA as the genetic material.
Avery, Hershey & Chase.
200
The Smooth Strain was known as? The Rough Strain was known as?
- Coated strain caused pneumonia = S Strain - Nocoated strain does not cause pneumonia = R Strain
200
What are the three main stages of Semiconservative Replication?
What is Unwinding, Base pairing & Joining.
200
What happens during Transcription?
Through transcription, the DNA code is transferred to mRNA in the nucleus.
200
What ensure that a gene is used at the right time and that proteins are made in the right amounts
What is Transcription Factors
200
Which bases are considered Purines and which are considered Pyrimidines?
- Purine Bases: Adenine and Guanine. - Pyrimidines Bases: Cytosine and Thymine.
300
Nucleotides consist of?
What is a five-carbon sugar, a phosphate group, and a nitrogenous base
300
How is DNA replicated in Eukaryotes and Prokaryotes?
- Eukaryotic DNA unwinds in multiple areas as DNA is replicated. - In prokaryotes, the circular DNA strand is opened at one origin of replication.
300
How many amino acids are there?
20 amino acids provide 20 different codes.
300
What is known to stop the mRNA from translating its message.
What is RNA Inteference
300
Please write out the Chargaff Rule.
What is C=G and T=A.
400
Cytosine and guanine bases pair to each other by?
What is three hydrogen bonds.
400
What is a DNA Helicase?
What is an enzyme that unwinds the double helix by breaking the hydrogen bonds between the complementary bases.
400
In translation, during the folded strand, there is a three-base coding sequence called the?
What is anticodon
400
What are the three types of mutations?
What is Point mutation, Insertion and Deletion
400
What does Photo 51 indicate?
Photo 51 indicated that DNA was a double helix or a twisted ladder shape, formed by two strands of nucleotides twisted around each other
500
What is two difference between DNA and RNA?
- DNA is missing an Oxygen opposed to RNA. - RNA has Uracil instead of Thymine.
500
What occurs during the base pairing stage in Semiconservative Replication?
DNA polymerase continues adding appropriate nucleotides to the chain by adding to the 3′ end of the new DNA strand.
500
In Transcription, what is the difference between the template strand and non template strand in
- Template strand – read by RNA polymerase, and mRNA is synthesized by a complement to the DNA nucleotides. - Nontemplate strand – not read by RNA Polymerase
500
What are Hox Genes?
Hox genes are responsible for the general body pattern of most animals.
500
Codon __ __ __ codes for the amino acid methionine and also functions as the start codon.
What is AUG
