Given the sequence of dna nucleotide bases tagtagtag, give the complementary strand of mrna produced during transcription.
a) aagguagua
b) aaucggaac
c) aucaucauc
d) gaggaggag

C) AUCAUCAUC

Explanation:

The mRNA is formed with nitrogenous bases complementary to the nitrogenous bases that the DNA strand (used as a template for the creation of RNA) possessed. However, RNA does not have the Thymine nitrogen base, instead the Uracila nitrogen base is placed. Accordingly, if the DNA base sequence used as template is adenine, thymine, guanine and cytosine (ATGC), the mRNA sequence will be uracil, adenine, guanine and cytosine (UAGC).

In the case of the above question, the DNA base sequence was TAGTAGTAG, from this we can say that the mRNA created from that DNA will have its AUCAUCAUC base sequence.

the earth is thought to have been formed about 4.6 billion years ago by collisions from a cloud of hydrogen, helium, rock, ice and other materials. these were pulled together by gravity to form objects in and around earth like- asteroids and small early planets called planetesimals.

so, the best possible answer to this question will be option d- to harden materials to form different parts of earth’s layers
