Halo, any of a wide range of atmospheric optical phenomena
The answer is letter D. The macronucleus is not exchanged during conjugation. <span>It normally contains the working duplicates/copies of genes necessary to support an enormous cell. Macronucleus is formed by a direct division of the polyploid nucleus right after conjugation then followed by series of internal gene replication that is not oftenly occurring in micronucleuse.</span>
Answer:
No
Explanation:
The universality of the genetic code refers to how the codons for amino acids are always the same in almost all species. Amino acids have corresponding nitrogenous bases in pairs of three called a codon. so to have the same amino acids, all species would need the same nitrogenous bases.
