The DNA base sequence AAA-CAG-CTG will code for what mRNA base sequence?
|
|
TTT-CAG-CTG
|
|
|
AAA-CAG-CTG
|
|
|
AAA-GUC-GAC
|
|
|
UUU-GUC-GAC
|
Explanation:
Detailed explanation-1: -The codons AAA, CCC, GGG, and UUU specify the amino acids lysine, proline, glycine, and phenylalanine, respectively.
Detailed explanation-2: -The given DNA sequence on DNA is: CGATTACAG. A on DNA will pair with U and C will pair with G. The corresponding mRNA sequence will be: GCUAAUGUC. Was this answer helpful?
Detailed explanation-3: -Each group of three bases in mRNA constitutes a codon, and each codon specifies a particular amino acid (hence, it is a triplet code). The mRNA sequence is thus used as a template to assemble-in order-the chain of amino acids that form a protein.
