A portion of the template strand of DNA has the following sequence 5\' GCT AAT CAC CGC ATC 3\' Assume the first codon for the peptide begins with the first nucleotide of the portion of mRNA and there are no introns (May not start at AUG). Enter the mRNA and amino acid sequence below Use the one letter abbreviations for the amino acids mRNA codons 5\' 3\' amino acids NH_2 COOH

Solution

out of the 2strands of DNA one acts as coding strand or a positive sense strand or template strand and the second is anticoding strand or negative sense strand ..

the gene encoding the polypeptide though may be present of anticodon strand during transcription i.e mRNA synthesis from parent DNA.. 5\' to 3\' strand being synthesised in the mRNA resembles to that of the coding strand of DNA due to complementary base pairing.., except for which thymine in dna is changed to uracil in rna...

so as per the above given sequence of dna strand... mRNA is 5\' GCU AAU CAC CGC AUC 3\'

So the amino acid sequence goes with ... alanine, aspargine, histdine, arginine, isoleucine.
