100
What is the name of the process of making mRNA?
What is transcription?
100
How does trait variation contribute to the process of natural selection?
It provides the raw material for natural selection to act upon.
100
What is antibiotic resistance? e?
The ability of bacteria to survive and grow in the presence of antibiotics that would normally kill them.
200
enzyme that is used in replication that breaks the hydrogen bonds
What is DNA helicase?
200
What nitrogen base is found in RNA but NOT DNA?
What is uracil or U?
200
What enzymes is involved in transcription?
What is RNA polymerase?
200
What is the primary source of trait variation in a population?
Genetic mutations.
200
What is the 2 mechanisms by which bacteria acquire antibiotic resistance?
Through genetic mutations and the transfer of resistance genes.
300
What are the base pair rules?
What is
A always with T
G always with C
300
How many nucleotides make up a codon?
What is 3?
300
Where does transcription occur?
What is the nucleus?
300
In natural selection, what is the role of the environment in shaping trait variations?
The environment acts as a selective pressure, favoring certain traits over others
300
What is the role of natural selection in antibiotic resistance?
Antibiotic use creates selective pressure, favoring the survival of bacteria with resistance traits.
400
enzyme that adds new nucleotides during replication
What is DNA polymerase?
400
What is the mRNA for this DNA sequence:
AAC GAT TTC
What is UUG CUA AAG?
400
What type of RNA is pictured here?
What is mRNA?
400
How does sexual reproduction contribute to trait variation in offspring?
It shuffles and recombines genetic material, creating unique combinations of traits.
400
How do bacteria share antibiotic resistance genes with each other?
Through mechanisms like horizontal gene transfer, including conjugation, transformation, and transduction.
500
the sugar in DNA
What is deoxyribose?
500
Where type of RNA is made in the nucleus?
What is mRNA?
500
What is the job of this type of RNA?
What is make peptide bonds between the amino acids?
500
What is the significance of trait variation in the long-term evolution of species?
It provides the material for the gradual accumulation of adaptations over generations.
500
In the Kirby-Bauer test, how is antibiotic resistance of a bacterial strain indicated on the agar plate?
A smaller or absent zone of inhibition around the antibiotic disk indicates resistance.
