Question

Q. 3 (table) Q. 4 Q. 5-6 (fill in the blank) 3. The first row of the table gives the nucleotide sequence in the non-template strand of a hypothetical mini-gene. (unrealistically small) Use the base-pairing rules to complete the table and do not forget start and stop codons e strand of DNA ATGGTATGA Template strand of DNA Transcription of template strand of DNA mRNA the mRNA molecule as a set of codons in the correct frame in the tRNA molecules which will the correct amino acids for translation 4. Which strand of DNA has the same nucleotide sequence as mRNA (taking into account that T in DNA is the equivalent of U in mRNA)? 5. Complete the following sentences to describe how the base-pairing rules contribute to transcription and translation. (circle correct answer) During transcription, each nucleotide in the strand of DNA is read by the (template/non-template) RNA polymerase and matched by the base-pairing rules to a nucleotide in the mRNA molecule. During translation, each the mRNA molecule is matched by the (anti codon/codon) base-pairing rules to the in in a tRNA molecule which brings the correct (anti-codon/codon) amino acid for that position in the growing polypeptide 6. Use the genetic code chart to complete the following sentence Translation of the mini-gene shown in question 3 will produce a polypeptide consisting of the amino acids linked together by a

Explanation / Answer

Answer 4: The Non template strand of DNA have the same nucleotide sequence as the the sequence of mRNA.

Answer 5:
