True or False. Nonhomologous endjoining usually alters the DNA by deletions or insertions.

The mutagen that most often causes thymine dimers is/are ________. Group of answer choices ultraviolet light reactive oxidants (free radicals) 5-bromouracil ethylmethane sulfonate acetaldehyde

True or False? The same DNA strand in the DNA double helix always functions as template during RNA production in the eukaryotic genome.

Please ASAP. Thank you

All of these DNA-repair mechanisms use an undamaged complementary DNA strand as a template for replacing the excised nucleotides EXCEPT for____ base-excision repair. homologous recombination. mismatch repair. nonhomologous end joining. nucleotide-excision repair

gene. If the JM109 strain is transformed by the PBKSK plasmid, the strain will produce the B-galactosidase (from the lac gene) and will hydrolyze X-gal to produce the blue compound. Therefore, colonies that were transformed and contain the pBSKS wil you appear blue.

5'-GCGGTACGTTACGGCTTTACTGACCTGCAGGC-3' A. Convert this to a double strand DNA molecule by writing the complementary sequence. Be sure to correctly label the ends of the double stranded molecule B. Pick one of the two strands and write the sequence of an RNA molecule that could be transcribed from it. Again, you must correctly label the ends of the molecule.

Fill in the blank. [x]  _________  genes are pairs of genes within an organism’s genome that have diverged from duplication events.

How did they get answer. Why did they do 2n?
