Explanation / Answer

22.What is the mRNA that will be produced. (Again start from the 5 prime end and list each complementary RNA base in order all the way to the 3 prime end.) template)

mRNA is processed in nucleus, where 7-methylguanosine is added to the 5' end of the initial RNA transcript referred as capping and poly A is added to the 3' end of the initial RNA transcript. The introns are then removed and the exons are spliced together.

23. What is the tRNA anticodon that will be needed to match the first mRNA codon in the sequence written for the answer to the previous question?

The first tRNA anticodon, UAC interact with the mRNA during the process of initiation.

24. What is the sequence of amino acids that will be produced by translating the mRNA sequence written for the answer to two questions above?

Each codon in the mRNA interact with specific anticodon on the tRNA molecule. The first tRNA, Meth-tRNA, with the anticodon UAC is the initiation codon. Each protein begins with an amino acid methionine at its amino terminal end. The next two codons present in the mRNA are UUU and AAA. The second tRNA,with the anticodon AAA and with phenylalanine attached, binds to the mRNA.Followed by tRNA with the anticodon UUU and the amino acid lysine attached until termination codon, UAA, UAG, and UGA does not code for an amino acid and signals the termination of protein synthesis.

26. How many codons are contained in the mRNA in the question 22?

approximately 300 to 350 codons contained in the mRNA
