Which of the following statements describes processes that occur during DNA replication?A DNA sequence is read by RNA polymerase, which produces another RNA strand complementary to the first strand. Two free-floating single strands of DNA are joined by polymerase. The polymerase finds the point at which the two strands will match up into a double strand. A double-stranded DNA molecule is unwound into single strands. Polymerase matches the right nucleotides to the single strand so that each forms a double strand of DNA. Messenger RNA are decoded by a ribosome to produce an amino acid chain. In the cell's cytoplasm, transfer RNA join the messenger RNA, forming a polypeptide.
