There are base pairing rules for writing complimentary DNA strands for a given strand.^ DNA Base Pairing Worksheet
A pairs with TC pairs with G In RNA, A pairs with U, instead of T. Write the complimentary DNA strand for each given strand of DNA.
1. CGTAAGCGCTAATTA
2. TCTTAAATGATCGATC
3. AATGAATAGCTAGCTT
4. GGCATTCGCGATCATG
5. CGTTAGCATGCTTCAT
6. ACTAACGGTAGCTAGC
Now write the mRNA strand for the given DNA strand.
7. ATGTCGCTGATACTGT
8. GAAGCGATCAGTTACG
9. AATGAATAGCTAGCTT
10. GGCATTCGCGATCATG
11. CGTTAGCATGCTTCAT
12. ACTAACGGTAGCTAGC
Write the tRNA sequence for the given strand of mRNA
- AGGUCAUGCAUGGGCAUGCAU 14.AGAGAUUCAGCUAGCACGAUA
15.GUCAUCGAUCGAUCGGAUGCC 16.UUUCAGUCAGCUAGCGAUCGU
Now you will translate the amino acid sequence for the given tRNA strand. Remember that codons are 3 base pairs long.
17. AUG CAC UGU CCU UUC GCU GAC
18. GAG AUC UGG UUG GAA UCG
19. AGC GUA UUA ACG UAU CAU
20. AGU CGA UCG AUG CGG AUG AUA
21. GUC GUC GAU AGC UAU CAU GCA
Transcribe the following DNA strand. Then translate the tRNA strand you wrote.
22. TGAGTCGACTGGCTGACCGTAGAC
23. CTTGGCTTATGGTGGTTCGCTCGC
- Using the following piece of DNA, give the mRNA molecule and the amino acid sequence for which it codes.
DNA- mRNA A T A T A A A C G A G G A A A T T C C G G G C G
tRNA Amino acids:
- Use the mRNA sequence to find the DNA sequence and the amino acid sequence. DNA
mRNA- A U G C C U A C A U G U G G U G U A A C C U U A
tRNA Amino acids For each codon below, give the tRNA anticodon.
- UUC _______ 4. AUC _______
- CCG _______ 6. CGU _______
- Give all the possible Anti-codons for the amino acids listed below. (Use page 244 in your text). Histidine (His) _________________________________________________ Isoleucine (Ile) _________________________________________________ Arginine (Arg) _________________________________________________ Tryptophan (Trp) _______________________________________________
