These are a) tRNA and mRNA b) tRNA and miRNA c) tRNA and rRNA d) rRNA and siRNA 16) The genetic code is said to be "degenerate" because a) there are more codons than amino acids. b) there are more amino acids than codons. c) different organisms use different codons to encode the same amino ac d) some codons specify more than one amino aci 17) How many unique mRNA codons can be constructed from the four different RNA nudeotides? a) 4 b) 8 c) 16 d) 32 e) 64 18) Specific amino acids are attached to tRNA molecules by a) activating enzymes. b) codons. d) ribosomes. e) initiation factors.Explanation / Answer
12. Both RNA and DNA polymerase that syntheses this molecule uses DNA as a template and synthesis new strands from 5’ to 3’
13. DNA only molecule is made of nucleotides joined by phosphodiester bond that connect the 2’OH to the 5’ phosphate
14. If the following DNA strand was used a template what would be sequence of an RNA be 5’GTACCGTC3’
3’-CATGGCAG-5’ DNA Coding strand
5’-GACGGUAC-3’ mRNA Sequence
15. To translate mRNA you require two other RNAs. These are tRNA and rRNA
16. The genetic code is said to be degenerate because there are more codons than amino acids
17. 64 unique mRNA codon can be constructed from the four different RNA nucleotides
18. Specific amino acids are attached to tRNA molecules by Activating enzymes.
