Answer:
Natural selection is defined as what?
Natural selection entails the ability of an organism to adapt to an environment and such adaptive traits are passed from parents to offspring
Explanation:
The law of natural selection was propounded by Charles Darwin which entails the survival of an organism by adapting to an environment and such adaptive trait is passed to offspring
A DNA sequence that is 15 nucleotides long would normally give rise to a polypeptide sequence that would be 5 amino acids long. This is assuming that all the nucleotides in the DNA sequences are strictly coded to form only sense codons and not a single nonsense codon, also called termination codon
A sense codon is a set of three nucleotides also called a triplet, that codes for a particular amino acid. A DNA sequence of 15 nucleotides has 5 codons.
A nonsense or termination codon is one that does not code for any amino acid. There are three nonsense codons found on mRNA, and these are UAA, UAG and UGA. So if the DNA sequence has one of these, then the amino acids in the polypeptide chain will be 4 in number
Under the right conditions they can all be melted
