Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which is the DNA complement of ATA GCG GCC?
A
TAT CGC GCC
B
ATA GCG GCC
C
TAT CGC CGG
D
UAU CGC CGG
Explanation: 

Detailed explanation-1: -The correct option is C The complementary DNA strand of the sequence ATGC will be TACG.

Detailed explanation-2: -The tRNA (transfer ribonucleic acid) anticodon for the GGU codon will be CCA, for GGC it will be CCG, for GGA it will be CCU, and for GGG it will be CCC. This is because each tRNA anticodon is complementary to the codons and form base pairs using RNA (ribonucleic acid) pairing rules.

Detailed explanation-3: -Genetic code CGC codes for arginine, UGU for cysteine and AUG codes for methionine.

Detailed explanation-4: -Three of the four nitrogenous bases that make up RNA-adenine (A), cytosine (C), and guanine (G)-are also found in DNA. In RNA, however, a base called uracil (U) replaces thymine (T) as the complementary nucleotide to adenine.
