Nucleic Acids and Proteins Flashcards
This polymerase is involved in initiation of DNA replication and has primase activity.
Pol a
This restriction enzyme digests and removes a methyl group from Adenine.
Type I
What is the name of the molecule that is added to the 5’ end of eukaryotic RNA transcripts?
GTP
What enzyme is crucial in the making of RNA from DNA?
RNA Polymerase
The hydroxyl group in a deoxyribonucleotide is expected to be found at which position of the sugar?
C3’
The purines are:
Adenine and guanine
the pyrimidines are:
thymine and cytosine
What signals the end of transcription?
Terminator
Which DNA polymerase is responsible for copying DNA by reading the existing strand, building new complimentary strand and always adds to 3’ end, but can’t start a new strand on it’s own?
DNA Polymerase III
What is the predominant form of DNA?
B Form
Which of the following is NOT a characteristic of eukaryotic DNA transcription? Multiple RNA Polymerases TATA-binding protein Strict Promoter Sequences Transcription Factors
Strict Promoter Sequences
What is the rate of DNA translation?
60 nucleotides per second
How many hydrogen bonds are formed between one C:G base pair?
3
This polymerase is involved in replicating mitochondrial DNA.
Pol y
Splicing is the process that does:
Remove introns and preserve exons
