Unformatted text preview: Individual: Reading Genes Refer to the following nucleic acid: 5- ATGCTATCATTGACCTTGAGTTATTAA 3 1) Is this a strand of DNA or RNA? How do you know? It is DNA since there is thymine (T) not uracil (U) in the sequence 2) If DNA, what is the complementary strand? The complementary strand is 5'-TACGATAGTAACTGGAACTCAATAATT- 3' 3) If this were the coding strand of a DNA molecule, what would the mRNA sequence be? 5-UACGAUAGUAACUGGAACUCAAUAAUU-3 4) If this were the non-coding strand of a DNA molecule, what would the mRNA sequence be? 5-AUGCUAUCAUUGACCUUGAGUUAUUAA-3 5) If DNA and a base were inserted at the beginning of the 5 end of the molecule, how would that affect protein synthesis and the resultant protein? (Hint: think about the code!) 6) If DNA and the G were deleted at the asterisk, how would this affect protein synthesis and the resultant protein? (Hint: think about the code!) If a base is inserted or deleted, the reading frame of tRNA would shift one base. If it is a coding strand, If a base is inserted or deleted, the reading frame of tRNA would shift one base....
