Gene A, which is normally expressed, has been moved by near an area of heterochromatin. None of the daughter cells produced after this recombination event express gene A, even though its DNA sequence is unchanged. Explain what happened.

Gene A, which is normally expressed, has been moved by DNA recombination near an area of heterochromatin. None of the daughter cells produced after this recombination event express gene A, even though its DNA sequence is unchanged. Explain this observation.
A base change mutation occurs within the -10 RNA polymerase binding site of the promoter region of gene. This mutation decreases the affinity of RNA polymerase for the -10 region. Which of the following are likely effects of this mutation? Gene A will not be transcribed. The protein encoded by the gene will be non-functional. Gene will be transcribed at a lower rate. Either A or B. Both A and B.
