Answer:
The fusion of two gametes to form a diploid zygote is called SYNGAMY.
Explanation:
During sexual reproduction process, exchange of DNA usually occur and this introduces diversity into the offspring that are produced. One of the ways by which exchange of DNA take place is called syngamy. Syngamy involves the bonding together of two sex cells leading to the formation of cell that has double amount of the chromosomes in the parent cells. The two cells that bond together are called gametes while the diploid cells formed is called zygote. The major function of syngamy is creation of variation; the genotypes in the formed zygote differ from those of the gametes.

Answer:
A. UUA AAG GCU UAC CCU
Explanation:
Transcription is the first process of Gene expression, which involves the synthesizing of a mRNA molecule from a DNA strand. This process (transcription) which is carried out or catalyzed by an enzyme called RNA polymerase, uses the complementary base pairing rule to synthesize nucleotides.
The complementary base pairing rule as proposed by Chargaff states that Adenine base (A) should bond with Thymine base (T). Likewise for Guanine (G) and Cytosine (C). Hence, in a DNA strand with sequence: AAT TTC CGA ATG GGA, the following RNA will result:
UUA AAG GCU UAC CCU.
Note that, Uracil base replaced Thymine base in the mRNA molecule.
Since; A-U and G-C
AAT TTC CGA ATG GGA ---------- DNA
UUA AAG GCU UAC CCU --------- RNA
