Name the 4 bases of DNA.
What is Adenine, Thymine, Guanine, and Cytosine?
100
DNA Helicase __________ and __________ the DNA strands.
What is unwinds and unzips?
100
This is the final product of transcription.
What is mRNA?
100
This enzyme is responsible for making the pre-mRNA strand in transcription.
What is RNA polymerase?
100
mRNA uses this base instead of thymine.
What is uracil?
200
These are the parts of a nucleotide.
What are the phosphate group, sugar, and nitrogenous base?
200
This strand is created continuously by DNA polymerase.
What is the leading strand?
200
These non-coding bases are spliced out of pre-mRNA.
What are introns?
200
This enzyme is responsible for laying down the starting indicators for DNA polymerase during replication.
What is RNA primase?
200
The poly-A tail is added to this end of pre-mRNA.
What is the 3' end?
300
This term is used to describe the opposite directions of the DNA strands.
What is anti-parallel?
300
This term is used to describe the fact that DNA replication keeps one old strand and creates one new strand.
What is semi-conservative?
300
Pre-mRNA must go through this process before exiting the nucleus.
What is pre-mRNA editing? (or splicing)
300
This enzyme is responsible for the cutting and combining of bases in pre-mRNA.
What is the spliceosome?
300
Her X-ray images of DNA inspired the first model of DNA.
Who is Rosalind Franklin?
400
This is the reason hydrogen bonds are used to keep base pairs together.
What is so that the strands can break apart for replication/transcription?
400
This is the reason that parts of DNA must be made is Okazaki fragments.
What is the DNA polymerase can only travel 3' to 5'? (or because the DNA helicase is heading in the opposite direction of the DNA polymerase)
400
Transcription is the first of two processes in the __________ ____________
What is the central dogma?
400
These enzymes as the starting place for transcription.
What are transcription factors?
400
This is a macromolecule made up of repeating subunits
What is a polymer?
500
This is the direction that DNA is twisted.
What is right-handed? (or clockwise)
500
If the original strand of DNA has 15% thymine, then one of the two identical strands of DNA has this much cytosine after replication.
What is 35%?
500
After the mRNA is edited, it exits the nucleus and finds a ___________ to initiate the process of ____________
What are ribosome and translation?
500
This enzyme is responsible for covalently bonding the backbone of the new strand in DNA replication.
What is DNA ligase?
500
After transcription, tRNA brings specific _______ _______ to the mRNA strand so that a ___________ can be made.
What are amino acids and protein?
