Answer:

Cell 3

Explanation:

One of the unique main characteristics that differentiates a prokaryote from a eukaryote is the absence of presence of nucleus in their cell, and where their DNA is found.

In prokaryotic cells, nucleus is absence. The DNA of prokaryote is not found in a nucleus, rather, it is contained in a region referred to as nucleoid.

Therefore, the specimen that does not have DNA in nucleus is definitely a prokaryote.

Cell 3 is a prokaryote.

Cys

Explanation:

tRNA or transfer RNA has an anticodon which base pairs with the complementary codon on mRNA or messenger RNA. It brings the amino acid corresponding to the codon present on mRNA. Since the tRNA here has anticodon ACG in 3' to 5' direction, the complementary codon on mRNA will be UGC in 5' to 3' direction. UGC codon corresponds to Cysteine amino acid which is abbreviated as Cys in three letters.

In this case, the coral reefs are pink and pink Isopod species with small bodies are likely to escape the predators. Hence the genetic combination Aa(pink body) and bb(small body) are more likely to survive and reproduce.
