The scientist anneals a mutant oligonucleotide to the original M13 DNA. Then DNA polymerase replicates the M13 DNA. After DNA synthesis, the scientist adds a restriction enzyme, EcoRI, that recognizes the DNA sequence 5′−GAATTC−3′5′−GAATTC−3′ and cuts after the guanosine nucleotide. Following the restriction digest, the scientist adds exonuclease III for a short period of time. Another round of DNA polymerase‑catalyzed DNA synthesis completes the procedure. What is the nucleotide mixture required by the DNA polymerase reaction in this procedure?

Scientists studied reproduction in the new zealand mud snail to answer the question, “are there benefits to reproducing sexually or asexually? ” which of these hypotheses would least likely aid the scientists as they worked to answer the question? sexual reproduction is advantageous over asexual reproduction because it reduces the rate of mutation accumulation. asexual reproduction is advantageous over sexual reproduction because it allows the snails to produce more offspring. sexual reproduction is advantageous over asexual reproduction because it allows for snails to have increased genetic variation. asexual reproduction is advantageous over sexual reproduction because it decreases the snails’ need for social
