Introduction:
The unit of genetic code, which has three
Again, new amino acid is carried by tRNA, which again binds to the complementary codon of mRNA. In this way, amino acids get linked to each other, forming the long chain of the polypeptides.

- Given the following DNA sequence from the template strand of a given gene: 5'CTTGCGTCACCTAAGACCTGTCATCG3' a) Write the mRNA that will be transcribed from the DNA sequence above (be sure to label the 5' and 3' ends) b) Write the peptide sequence translated from the mRNA produced in part a.arrow_forwardAnswer the following whether it is TRUE or FALSE: 1. For each DNA segment 3'-ACCTGCCTACCCG-5' the sequence of the mRNA molecule synthesized is 5'-TGGACGGATGGGC-3' 2. In the template strand TACCGAGGTATGTAC, the coding strand is 5'-ATGGCTCCATACATG-3'. 3. In the template strand TACCGAGGTATGTAC, the coding strand is 5'-AUGGCUCCAUACAUG-3'. 4. The template strand is the strand of DNA used for RNA synthesis. 5. Transcription forms a messenger RNA molecule with a sequence that is identical to the DNA template from which it is prepared.arrow_forwardGiven the following DNA sequence of the template strand for a given gene: 5' TTTCCGTCTCAGGGCTGAAAATGTTTGCTCATCGAACGC3' Part A ) Write the mRNA that will be transcribed from the DNA sequence above (be sure to label the 5' and 3' ends). Part B ) Use the genetic code to write the peptide sequence translated in a cell from the mRNA in part A. Please use the 3 letter abbreviation for each amino acid. Part C: How would the peptide synthesized in a cell be different if the mRNA was translated in vitro (i.e. not in the cell)?arrow_forward
