Detailed explanation-1: -In order for a gene in DNA to be converted into a protein, it needs to go through two steps. The first step is called transcription, and it produces mRNA. The second step is called translation, where the sequence of mRNA is converted into a sequence of amino acids to form a polypeptide.
Detailed explanation-2: -In order for a cell to manufacture these proteins, specific genes within its DNA must first be transcribed into molecules of mRNA; then, these transcripts must be translated into chains of amino acids, which later fold into fully functional proteins.
Detailed explanation-3: -DNA utilizes four bases, adenine (A), guanine (G), cytosine (C), and thymine (T), in its code. RNA also uses four bases. However, instead of using ‘T’ as DNA does, it uses uracil (U). Therefore, if your DNA sequence is 3’ T C G T T C A G T 5’, the mRNA sequence would be 5’ A G C A A G U C A 3’.
Detailed explanation-4: -Answer and Explanation: The correct answer is (A) DNA-mRNA-tRNA-protein.
