Deoxyribonucleic Acid
What is the process called where DNA is replicated to make more strands of DNA?
Replication
What is the relationship between the two DNA strands during replication?
Antiparallel
What is the name of the enzyme that separates the DNA strands during replication?
Helicase
What is the relationship between the new and old DNA strands during replication?
The new strands are a combination of old and new material.
How many hydrogen bonds are formed between a Cytosine and Guanine nucleotide pair?
3
What are the four nitrogenous bases found in DNA?
Adenine, Thymine, Guanine, Cytosine
What is the role of the enzyme 'primase' in DNA replication?
Primase creates a 'primer' that marks the creation of new DNA strands
What is the direction of DNA synthesis by the polymerase enzyme?
The polymerase enzyme can only add bases in the 5' to 3' direction
What is the role of the 'ligase' enzyme in DNA replication?
Ligase seals up the DNA strands after the polymerase adds the complementary bases
What is the direction of RNA synthesis by the RNA polymerase enzyme?
RNA polymerase synthesizes RNA in the 5' to 3' direction
What is the role of the 'exonuclease' enzyme in protein synthesis?
Exonuclease removes the RNA primers from the messenger RNA before it can be used as a template for protein synthesis
What is the main function of a codon?
To specify a particular amino acid in protein synthesis
What is the role of tRNA in protein synthesis?
To carry amino acids to the ribosome
What is the first step in the decoding process of protein synthesis?
Get the 3-base code of the DNA
Which of the following is an example of a mutagen?
Ultraviolet radiation
What is the main function of DNA replication?
To create identical copies of the DNA molecule
