Answer:

A. True

Explanation:

Allolactose is an example of an inducer, a small molecule that triggers expression of a gene or operon. The lac operon is considered an inducible operon because it is usually turned off (repressed), but can be turned on in the presence of the inducer allolactose.

During DNA Replication, a DNA strand that has the bases 3'ATACGC5' produces a strand with the bases
Gemiola [76]

During DNA Replication, the DNA strand that has the bases 3'ATACGC5' produces a strand with the bases 5'TATGCG3'  

Answer: Option B

<u>Explanation:</u>

The DNA Replication produces the newly formed two complimentary base pair strand from the two template base pair strand, so basically the already existing DNA strand is replicated, in order to produce complimentary DNA strand, with the template giving one strand to new each.

Thereby, here the given base was 3' ATACGC 5' so the first thing to produce the strand will be that the coding end will be reversed so the 3' end will have 5' end and 5' end will have 3' end. Then A bonds with T and T bonds with A and, so C bonds with G and G bonds with C, therefore, ATACGC will produce TATGCG. Thereby, answer would be 5'TATGCG3'.
