DNA Biology Chapter 22 Flashcards
How many strands of DNA have vs. RNA
2
1
What kind of sugar does DNA have vs. RNA
deoxyribose
ribose
What kind of bases does DNA have vs RNA
ATCG
AUCG
What kind of backbone does DNA have vs RNA
sugar/phosphate
Sugar/phosphate
Forms the small and large subunits of ribosomes
Ribosomal RNA
Carries genetic information from DNA to ribosomes in the nucleus. DNA serves as a template for its formation
Messenger RNA
Transfers amino acids to ribosomes. Each carries only one type of amino acid, thereby there are 20 different types of these.
Transfer RNA
DNA replication happens in the __ phase of the cell cycle
S
Original strand being copied
Template strand
New strands
Copies of the template strand
Daughter strand
Makes DNA polymers
Builds daughter strands
Builder
connects complimentary RNA bases to DNA
DNA polymerase
Breaks the DNA double helix
“unzips” DNA in preparation for a copy to be made
DNA helicase
Any heritable change in the base sequence of DNA
Can occur during DNA replication
Another source of variability
mutation
DNA to RNA to Protein to Trait
