MRNa's are composed of codons. Codons are a sequence of three nucleotides that come together to be transcribed by an anti-codon to form units for genetic coding. For example, AUG is a codon and upon transcribing becomes the protein Methionine. In this case, they differ in the terminal codon. UAG is a stop codon while UAC is Tyrosine. The first sequence is complete,while the other one is not.
He observed dairymaids milking cows with cowpox to see if the statement was true before forming a hypothesis.
The correct answer is A. Phenotypes
Explanation:
In genetics, the observable traits of an organism that includes behavior, physical traits, biochemical properties, etc. are known as phenotypes. These traits depend on both the genes of the organism (genotype) and the influence of the environment. Due to this, organisms of the same species with a similar genotype can display different phenotypes. This occurs in the case of Patrick and Michael as their observable traits or phenotype is different despite they are brothers. Thus, the observable characteristics are the phenotypes of an organism.
