A mutation
B. The amino acid sequence may be altered during protein synthesis.
Mutations can occur during DNA replication, cell division, or exposure to environmental factors like radiation or chemicals. They are more likely to occur in rapidly dividing cells, such as during development or in cancer cells.
a change in the sequence of amino acids. -P
A nucleotide in DNA consists of a sugar (deoxyribose), a phosphate group, and a nitrogenous base. The pair of molecules that would most likely be found in a nucleotide are deoxyribose (a sugar molecule) and a nitrogenous base (such as adenine, cytosine, guanine, or thymine).

This change was most likely caused by a point mutation called a missense mutation. Missense mutations involve the substitution of a single nucleotide in the DNA sequence, leading to a change in one amino acid in the protein sequence. In this case, the substitution of a single nucleotide led to the change from tyrosine to histidine in the protein sequence.
A mutation in a DNA nucleotide sequence would be more harmful than a mutation in a mRNA nucleotide sequence because it could cause the synthesis of multiple nonfunctional proteins in comparison to a mutation in a mRNA nucleotide sequence that would be less harmful because it would result in a few nonfunctional proteins.
A hydrophobic molecule is more likely to be nonpolar.
sequence of subunits in DNA.
A silent mutation, where a change in the DNA sequence does not result in a change to the amino acid sequence of the protein, is likely to have the least effect on an organism. This is because the protein produced is unaffected, and therefore the organism's functioning remains unchanged.
A nucleotide in DNA typically consists of a deoxyribose sugar molecule bound to a phosphate group, along with a nitrogenous base such as adenine, thymine, guanine, or cytosine. The deoxyribose sugar and phosphate group make up the backbone of the DNA strand, while the nitrogenous base is attached to the sugar and varies among the different nucleotides.
