The sisters have different traits because their DNA contains different ORDER OF NUCLEOTIDES (Option A).
DNA is a double helix composed of two long chains of nucleotides.
In DNA, there are four types of nucleotides, each containing one different nitrogenous base, i.e., Adenine, Guanine, Thymine and Cytosine.
During gene transcription, a fragment of DNA called gene is used as template to create an mRNA, which is in turn used as template to create a protein.
The order of nucleotides in a given gene sequence determines the sequence in mRNA and ultimately also the protein sequence that's synthesized from this sequence.
In conclusion, the sisters have different traits because their DNA contains different ORDER OF NUCLEOTIDES (Option A).

Animal research is critically important for studying variables that can't be ethically tested in human subjects. Ethical regulations ensure the humane treatment of animal subjects and the minimization of pain and distress. Animal research is a privilege granted by society to researchers.
Animal research is critically important for the study of variables that can't be tested ethically in human subjects. Ethical considerations have necessitated strict regulations on animal research, such as the approval of an IACUC and regular inspections of animal facilities. The use of animals in research is a privilege granted by society to researchers, and efforts are made to minimize pain and distress experienced by animal subjects.

Answer;
Kingdom Eubacteria
A unicellular kingdom that does not have a nucleus would belong in the kingdom Eubacteria.
Explanation;
Kingdom Eubacteria is the kingdom of prokaryotic, single-celled organisms that lack a membrane-enclosed nucleus and can be classified by shape.
Prokaryotes are organisms that lack nucleus and other membrane bound organelles, such as mitochondria. Unicellular means that the organism is made of one cell.
Polysaccharides are complex sugars or carbohydrates.
There are two types of polysaccharides in plants: cellulose and starch.
Polysaccharides generally perform two functions: energy storage and structural support.
Polysaccharides, also called glycan, are the form in which most natural carbohydrates occur. Polysaccharides may have a molecular structure that is either branched or linear.
Types Of Polysaccharides
Cellulose: The cell wall of the plants is made up of cellulose.
Starch: It is formed by the condensation of amylose and amylopectin.
Glycogen: It is made up of a large chain of molecules.
Inulin: It is made up of a number of fructofuranose molecules linked together in chains.
