A DNA sequence reads: TACGATCATATT. Which of the following is the correct complementary DNA strand?
ATGCTAGTATAA
AUGCUAGUAUAA
CGTAGCTGCGCA
GCAUCGAGUAUA

Respuesta :

TACGATCATATT is what you have.
ATGCTAGTATAA is what you’d get.
A matches with T, G matches with C, and the U would only come into play if you were translating out of the DNA sequence.

The complementary strand of a DNA sequence that reads TACGATCATATT is ATGCTAGTATAA.

  • Deoxyribonucleic acid (DNA) is made up of nucleotide subunits and functions in the storage of genetic information for living cells.

  • There are four nucleotides that constitutes the DNA molecule namely: Adenine (A), Thymine (T), Guanine (G) and Cytosine (C).

  • In a DNA molecule, adenine (A) base pairs Thymine (T) while Guanine (G) pairs Cytosine (C) i.e. A-T, G-C.

  • According to this question, a DNA molecule with the following sequence was given: TACGATCATATT. The complementary sequence of this DNA strand is ATGCTAGTATAA.
