The genetic code is carried by the DNA molecule in most organisms. DNA is the store for hereditary information.
In eukaryotic cells, DNA is found in the cell nucleus, while in prokaryotes it is found in the nucleosome.
The genetic code is the triplets of nucleotides in DNA and RNA that define and direct which amino acid is used in protein synthesis.
The genetic code is expressed in 64 different triplet combinations that code for different amino acids. Three of these triplets are called non sense triplets or codons because they do not code for any amino acid. The rest are sense codons.
The answer is stabilizing selection.
<span>Sickle-cell anemia is a recessive disorder caused by the presence of two recessive alleles "s", so genotype is "ss". This disorder is characterized by sickle hemoglobin. In an area with malaria, heterozygous individuals "Ss" (with one dominant allele and one recessive allele) have an advantage. These individuals will have both normal and sickle hemoglobin. But pathogen that causes malaria affect only normal hemoglobin, so heterozygous individuals will have half of the hemoglobin resistant to the pathogen and those individuals are resistant to malaria.</span>
Stabilizing selection favors heterozygotes Ss, disruptive selection favors dominant (SS) and recessive (ss) homozygotes, while directional selection favors dominant (SS) or recessive (ss) homozygote. Since in this example, people with genotype Ss (heterozygotes) are in advantage, then this is an example of stabilizing selection.
