Nucleic Acids
100
The first enzyme used in DNA synthesis.
What is helicase?
100
This enzyme does all the work for transcribing mRNA.
What is RNA Polymerase?
100
Most tRNA molecules enter through this site in the ribosome.
What is the A site?
100
This principle says that analysis of DNA always shows equal amounts of A and T, as well as equal amounts of C and G.
What is Chargaff's rule?
200
Segments of DNA that result from having to replace RNA primers.
What are Okazaki fragments?
200
This is the area where RNA begins transcribing.
What is the promoter region/TATA box?
200
When attached to the ribosome, codons are found on which type of molecule?
What is mRNA?
200
These molecules contain anticodons.
What is tRNA?
300
This enzyme prevents DNA strands from tangling when opened apart.
What is topoisomerase?
300
This is the product of transcription, before RNA processing.
What is pre-mRNA?
300
The first tRNA molecule enters at this site in the ribosome.
What is the P site?
300
DNA replication forms a leading and lagging strand because it must maintain this characteristic.
What is antiparallel?
400
The enzyme that adds RNA nucleotides to the DNA strand.
What is primase?
400
In RNA processing, these remove introns and put exons back together.
What are splicesomes/snRNPs?
400
This is what is produced in a ribosome.
What is a polypeptide?
400
The primary component of ribosomes.
What is rRNA?
500
When making DNA, the parent strand must always run in this direction.
What is 3' to 5'?
500
The location where mRNA is made.
What is the nucleolus?
500
This section of the mRNA strand helps it bind to the small ribosomal subunit.
What is the UTR (untranslated region)?
500
The template strand sequence for the start codon.
What is TAC?
