How to decode DNA sequences? Must use the codon chart..
During the process of transcription, DNA is unwound into a single strand exposing bases adenosine (A), thymine (T), guanine (G), and cytosine (C). These bases are complimentary, A pairs with T and C pairs with G. As the process of transcription occurs a single strand of mRNA is made. In RNA the thymine base is replaced with uracil (U). The mRNA forms groups of three bases called codons. The tRNA matches the mRNA codon to its anticodon that has the protein attached.
Decode the following DNA sequences into a chain of proteins using the codon chart that is included.
DNA Triplet RNA Codon Amino Acid
TAC AUG Start – Methionine
ATC UAG Stop
AAA UUU Phenylalanine
AGG UCC Serine
ACA UGU Cysteine
GGG CCC Proline
GAA CUU Leucine
GCT CGA Arginine
TTT AAA Lysine
TGC ACG Threonine
CCG GGC Glycine
CTC GAG Glutamic Acid

I’m having difficulty and just need to make sure I’m doing them correctly.
