Answer:
According to the semi-conservative DNA replication, the AATTA sequence is transcribed into a new strand as TTAAT, taking into account the complementarity of nitrogenous bases.
Step-by-step explanation:
Semi-conservative DNA replication means that two molecules are obtained from a double-stranded DNA molecule, each with an original strand and a new strand.
The DNA is composed of sequences of nitrogenous bases, which are adenine (A), guanine (G), thymine (T) and cytosine (C). The bases of one chain are matched with the bases of another, according to the complementarity of nitrogenous bases, where:
- Adenine is complemented with Thymine A=T
- Guanine is complemented with Cytosine G≡C
Then, for the sequence AATTA of the strand DNA mold, the sequence on the new strand would be complementary, i.e., TTAAT.
