INSTRUCTIONS You may print out this assignment and fill it in by hand. We suggest using pencil in case you make mistakes!! Submit your Assignment as a single doc on Canvas. ASSIGNMENT 1) For the DNA sequence given below, write the complementary DNA sequence that would complete the double-strand. DNA 3-A TTGCT TACTTGCA T-5° DNA 5 2) Does it matter which strand is the 'code strand'? The following two sequences look identical, except one runs 3-5' and the other 5'-3'. For each DNA sequence given below, write the mRNA sequence that would be coded from it. Make sure you indicate the direction of each mRNA strand (i.e. 3' and 5'ends). Use the Universal triplet code to determine the sequence of amino acids that would be generated for each of the mRNA sequences that you generated in question 2. Remember that the reading of mRNA goes in the 5'-3' direction (see lab notes for examples). . To make the mRNA, read from LEFT TO RIGHT- To make the amino acid, read triplets from Left to Right DNA 3-TACCTACTTTGCCCGATCCAT-5' mRNA 5... amino acid b. Read letter by letter from RIGHT TO LEFT To make the amino acid, read triplets from Left to Right DNA 5'-TACCTACTTTGCCCGATCCAT-3 mRNA 5. amino acid c. Are the amino acid sequences in a and b the same? YES_

Answer 1

1) complementary dna strand:

1) DNA (Complementary strand is) 3-ATTGCYTACTTGCAT-5. 5. TAAC, AAT, AA (GTA - 3" 2)DNA al 3-TACCTACTIT GCC CGATCCAT-S' mRNAS' À UGG AUGAAA C G G G CUAGGUA-3 amino and | AUG GAU GAA ACG G G C UAG GUA MeP ASP Glu The Gly Stop Val b) DNA- 15'- TACCIACIIT GCCCGAT CCAI 3' mRNA 3' AUGGA UG AAA CGGG CUAGGUA 5 amino and TAUG GANGAA ACG GAC VAG GUA Yes the amino same but the acid sequences are direction of strand us opposite
