Iove aIung theHRNA from codon to codon, the appropriate amino acids are brought into place and linked togetheraccording to the sequence of codons. Thus, the code in the mRNA is translated into a specialsequence of amino acids. The order of the amino acids in the protein, therefore, is specified by theMRNA, 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 nucleotidesdetermined by the order of the nucleotides in the DNA. As the mRNA forms, uracil (U) nucleotidesmatch 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 DNAsegment on which it formed. For example, where the DNA contained quanine, the MRNA containscytosine. Where the DNA contained adenine, the MRNA contains uracil. After the single-strandedmolecule of MRNA is formed, it moves out of the nucleus into the cytoplasm.1. One strand of DNA has the base sequence: CGATTGGCAGTCAT. Determine thesequence 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 theprocess occur in the cell?
