Transposition (insertion of a transposon into a DNA sequence) results in the formation of base substitution mutations in a cell's DNA
In the figure, if enzyme A is a repressible enzyme, compound C would
bind to the corepressor for Gene a
if you knew the sequence of nucleotides within a gene, which one of the following could you determine with the most accuracy?
A. the tertiary structure of the protein
B. the quaternary structure of the protein
C. the primary structure of the protein
D. the secondary structure of the protein
E. The answer cannot be determined based on the information provided.
In the figure, the antibiotic chloramphenicol binds the 50S large subunit of a ribosome as shown (the light gray area is the large subunit, while the black shape is the drug). From this information you can conclude that chloramphenicol
Refer to the table The anticodon for valine is
An enzyme that catalyzes the cutting and resealing of DNA, and is translated from insertion sequences, is
What is transformation?
Refer to the table. Identify the sequence of amino acids encoded by
the following sequence of bases in a strand of DNA (pay attention to
the polarity of the DNA here):
B. Translation would stop at the first codon
Conjugation differs from reproduction because conjugation
Refer to the table. When amino acid sequences from a cell cycle control protein from a patient with cancer and a healthy person are aligned, the sequence from the cancer patient indicates one amino acid has changed from phenylalanine (Phe) to leucine (Leu). A mutation in the cancer patient's DNA must have taken place. Identify the result of this DNA change in the mRNA codon that led to this change in the protein sequence.
An enzyme produced in response to the presence of a substrate is called a(n)
Both base substitution and frameshift mutations can result in the formation of premature stop codons.
Genetic change in bacteria can be brought about by
Which of the following enzymes unwinds the two strands of DNA so that they can be copied during replication?
A gene is defined as
Recombination will always alter a cell's genotype.
The mechanism by which the presence of glucose inhibits the lac operon is
In the figure, if enzyme A is an inducible enzyme,
