Answer:
DNA Sequence: TAC-GTG-TTA-GTC-TAA-GAA-ACT
A. 1- mRNA: UAC-GUG-UUA-GUC-UAA-GAA-ACU
2- Amino acid sequence (5'3' Frame): Tyrosine-Valine-Leucine-Valine-stop codon-Glutamic acid-Threonine (abbreviation: YVLV-ET)
B. 1- mRNA: UAC-UGU-UAG-UCU-AAG-AAA-CU
2- Amino acid sequence (5'3' Frame): Tyrosine-Cysteine-stop codon-Serine-Lysine-Lysine (abbreviation: YC-SKK)
Step-by-step explanation:
Transcription is a cellular mechanism where a specific sequence of a DNA strand is used as template to synthesize an RNA molecule, often a messenger RNA (mRNA) molecule that is subsequently utilized to create an ordered sequence of amino acids (i.e., a protein) by a mechanism referred to as translation. In RNA, uracil (U) always replaces thymine (T) bases. During translation, the mRNA is "read" according to the genetic code which associates the DNA sequence to the amino acid sequence in the polypeptide chain. For such purpose, each triplet of nucleotides or 'codon' in the mRNA specifies one aminoacid or one-stop codon (stop codons are UAA, UAG, UGA).
