The name of the enzyme that unwinds the DNA and prepares for replication.
What is helicase?
100
Transcription occurs in this part of the cell.
What is the nucleus?
100
The type of reaction that occurs when a peptide bond if formed?
What is a condensation reaction?
100
The number of ribosomal subunits.
What is 2- large and small?
200
The reason why DNA is considered anti-parallel.
What is the strands are running in opposite directions.
200
DNA replication occurs in this direction.
What is 5' to 3'?
200
The product of transcription.
What is mRNA?
200
The difference between a codon and an anti-codon.
What is a codon is 3 bases of mRNA and an anti-codon is 3 bases that are part of tRNA?
200
The two elements that are bonded in a polypeptide bond?
What is carbon and nitrogen?
300
The protein that ensures that DNA can be coiled enough to be held in a single cell.
What is a histone?
300
The meaning of DNA being semi-conservative.
What is the new strands are like one of the parent strands?
300
The difference between the sense and anti-sense strands?
What is the anti-sense strand is the DNA strand from which the mRNA is coded. The sense strand is the same as the mRNA.
300
The site where proteins destined for export are made?
What is the attached ribosomes on ER?
300
The possible number of amino acids that can make up a polypeptide.
What is 20?
400
The relationship between the number of purines or the number of pyrimidines in a piece of DNA.
What is there is the same ration of purine bases and the same number ofpyrimidine bases.
400
The purpose of the Okazaki fragments.
What is they allow the lagging strand to add new bases at the 3' end?
400
Transcription occurs in this direction.
What is 5' to 3'?
400
The last site on the ribosome before the amino acid becomes part of the polypeptide.
What is the e-site?
400
The difference between translocation and termination?
What is translocation is when tRNA moves from the A-site to the P-site to the E-site in the ribosome and termination occurs when a stop codon is recognized and the polypeptide is complete.
500
The difference between exons and introns.
What is introns are cut out of DNA and exons are coded for proteins?
500
The name of the enzyme that serves as the site for replication.
What is DNA polymerase?
500
The difference between intermediate mRNA and mature mRNA?
What is mature mRNA has taken out introns so that it is ready for translation and protein synthesis?
500
The role of methionine in translation.
What is it acts as the initiator for translation at the ribosomal subunit?
500
The purpose of a polysome.
What is translating mRNA into proteins at more than one site?
