RNA Structure
Transcription
100
Watson and Crick used this term to describe the shape of DNA.
Double helix?
100
This is what results from copying one molecule of DNA
A strand of RNA is produced
100
A long, single stranded sequence of RNA. (Use full name)
messenger RNA (mRNA)?
100
The sugar in RNA
ribose?
100
What replaces T in the RNA sequence
"U"
200
The sugars and the phosphates.
The "backbone of a DNA molecule"?
200
This is the first step in the replication of one DNA molecule.
The unwinding of DNA
200
This type of RNA carries an amino acid. (Use full name)
transfer RNA (tRNA)?
200
Which of the following is found in RNA nucleotides but not in DNA nucleotides?
Deoxyribose?
200
What is the first step in Transcription
RNA polymerase binds to specific sequence of DNA that acts as a signal to start transcription?
300
The type of bond that holds bases together in the double helix.
A hydrogen bond?
300
This is what you call a "G" binding with a "C" or an "A" binding with a "T".
A base pair?
300
This type of RNA assembles itself into an "apple with a hole in it" through which mRNA can slither. (Use full name)
ribosomal RNA (rRNA)?
300
This is where translation takes place.
The cytoplasm?
300
What happens in transcription?
When DNA makes mRNA
400
A (nitrogenous) base, a sugar, and a phosphate.
The 3 parts of a nucleotide?
400
The enzyme that is used to make a copy of a DNA molecule.
DNA polymerase?
400
Where is an anticodon found on
transfer RNA
400
What are the three types of RNA?
mRNA, tRNA, rRNA?
400
Where does transcription take place?
The nucleus?
500
How many amino acids are in a protien
20
500
The proteins which the DNA double helix winds around so that DNA can become "supercoiled".
histones?
500
The structure serve as a site where proteins are synthesized?
rRNA
500
The making of RNA based on information in the DNA is called?
Transcription?
500
How does RNA polymerase know where to start and stop making an RNA copy of DNA?
RNA polymerase will only bind to regions of DNA called Promoters?
