Express this sense sequence as a polypeptide. Use the three letter abbreviation and separate the amino acids with a dash - e.g.
jek_recluse [69]

Answer:

- Protein sequence: Met-Pro-Gly-Lys-Ile-Arg-Arg-Pro-Pro-Gly-Thr-Pro-Leu-Phe-Gly-Lys-*

- DNA 5' UTR: ATTTTAGCC

- RNA 3' UTR: UAAAAAUAAAAU

Explanation:

Transcription is the process in which a DNA sequence (e.g., a gene) is used as template (transcribed) in order to synthesize an RNA molecule, usually a messenger RNA molecule, which is then used as template to produce a polypeptide sequence (protein) in the ribosomes. In RNA, Thymine (T) bases are always replaced by Uracil (U) bases. An mRNA strand is formed in the 5′ to 3′ direction. Each triplet of nucleotides is referred to as a codon and the resulting mRNA strand is translated starting from codon AUG (Methionine), while there are three different stop codons or 'or termination codons' in the genetic code that terminate translation: UAG, UAA, and UGA.
