Asap when studying heredity, what is the relationship of dna bases and traits?

Heredity is the study of how traits are passed from parents to offsprings through reproduction. Off springs cells acquire the genetic information from their parents. DNA bases (A,G,C,T) determine the nucleotides that will constitute the mRNA, the mRNA nucleotides determines the codons which codes for certain amino acids. The amino acids join during translation and form peptides that then join to form proteins. These proteins include enzymes that catalyses chemical reactions for example pigments of skin and hair color are produced by enzymes. Hence, proteins highly determine the traits acquired by a given organisms and therefore, variation in a gene in terms of the bases greatly affect the proteins formed hence influencing the traits of the organisms.

Bases make up DNA and the DNA contained in genes controls the expressed traits of in individual organism.

Heredity refers to the fact that organisms inherit certain traits from their parents. The terms associated with heredity are:

Bases: These are the compounds that come together to form the molecules that control  of inheritance called DNA.DNA: These are the molecules that control certain functions and features in the body found in the genes.Traits: These are the characteristics exhibited by individual organisms.

Hence bases make up DNA and the DNA contained in genes controls the expressed traits of in individual organism.

The problem here is that according to aufbau principle before 3d orbital 4s subshell comes.after filling 3p orbital with electrons you have 4 electrons left, you place two in 4s with opposite spin and the other two in 3d in any of its two orbitals of total five orbitals with the same spin.

The answer is b because c don't explain why the moths are on them and it isn't a because as we know only one species of moth does this
