Final answer:
The student's assertion regarding the RNA sequence is incorrect because RNA synthesis uses the antisense strand of DNA as a template and replaces thymine with uracil. The correct mRNA and amino acid sequence should be determined based on the antisense DNA strand and the genetic code, respectively.
Step-by-step explanation:
The student's claim that the RNA produced from the given DNA sequence is 3'-GGCATGGCAATATTGTAGTA-5' is incorrect for two primary reasons. Firstly, RNA is synthesized using the antisense DNA strand as a template, not the sense strand. Secondly, during transcription, the nucleotide thymine (T) in DNA is replaced by uracil (U) in RNA.
For the DNA sequence 3'......GCT GTC AAA TTC GAT......5', the complementary mRNA sequence would be 5'......CGA CAG UUU AAG CUA......3'. The genetic code chart can then be used to determine the corresponding amino acid sequence that would be synthesized.
For example, with the given DNA sequence 5'-ATGGCCGGTTATTAAGCA-3', transcription would result in a complementary mRNA sequence 5'-AUGGCCGGUUAUUAAGCA-3', where 'T's are replaced by 'U's. Translation of this mRNA would lead to the assembly of a specific amino acid sequence, starting from the N-terminus to the C-terminus, based on the genetic code.
