Extracted text: Iove aIung the HRNA from codon to codon, the appropriate amino acids are brought into place and linked together according to the sequence of codons. Thus, the code in the mRNA is translated into a special sequence of amino acids. The order of the amino acids in the protein, therefore, is specified by the MRNA, which in turn is transcribed from the DNA. Procedures and Observations: During transcription, the DNA double helix unwinds and "unzips. The two strands separate as the hydrogen bonds binding the nitrogen bases break. Then, nucleotides present in the cell line up along one strand of the DNA, the order of the nucleotides determined by the order of the nucleotides in the DNA. As the mRNA forms, uracil (U) nucleotides match with adenine (A) nucleotides; cytosine (C) nucleotides match with guanine (G) nucleotides. Note: RNA contains uracil (U) nucleotides where thymine (T) nucleotides would occur in DNA. The nucleotides in the newly formed mRNA are complementary to the nucleotides of the DNA segment on which it formed. For example, where the DNA contained quanine, the MRNA contains cytosine. Where the DNA contained adenine, the MRNA contains uracil. After the single-stranded molecule of MRNA is formed, it moves out of the nucleus into the cytoplasm. 1. One strand of DNA has the base sequence: CGATTGGCAGTCAT. Determine the sequence of bases in the complementary strand of mRNA that would form next to this DNA strand. a. Write the sequence of bases in the complementary MRNA strand below. b. What is this process called? Where does the process occur in the cell?
