Which of the following statements about rna polymerase in transcription is correct? rna polymerase is an enzyme that synthesizes an mrna strand. rna polymerase is an anti-codon that synthesizes an mrna strand. rna polymerase is a gene that synthesizes an mrna strand. rna polymerase is a ribosome that synthesizes an mrna strand

RNA polymerase, also known as DNA-dependent RNA polymerase, is an enzyme that produces primary transcript RNA. In cells, RNAP is necessary for constructing RNA chains using DNA genes as templates, a process called transcription.

As I stated RNA Polymerase is a Enzyme. So your answer would be A. :)

Hope I helped. :) Thanks or using .  

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
