If the sequence of bases in the DNA is ATTCGATG (POLARITY IS 5’ TO 3’), THEN THE SEQUENCES OF BASES IN THE TRANSCRIPT WILL BE
|
|
ATTCGAAG
|
|
|
TAAGCTAC
|
|
|
AUUCGAUG
|
|
|
NONE OF THE ABOVE
|
Explanation:
Detailed explanation-1: -So, the sequence of the complimentary strand in 5’ to 3’ direction is 5’-GCATGCATGCATGCATGCATGCATGCAT− 3’.
Detailed explanation-2: -mRNA strand is complementary to one of the DNA strands i.e., template strand. In RNA, uracil is present instead of thymine which is complementary to adenine. Cytosine and guanine are also complementary to each other. Hence, the sequence of bases in transcript would be CGAAUCCGUIJ.
Detailed explanation-3: -The sequence of nitrogenous bases in one strand of DNA are 3’ TAC GCG ACG 5’ .
Detailed explanation-4: -The four bases in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T). These bases form specific pairs (A with T, and G with C).
