WebMar 9, 2024 · A mutation causing a single base pair change in DNA does not change the iconic ds-stranded DNA structure. If it did, DNA would not be a reliable molecule to store and read out the genetic blueprint. In contrast, a single mutation in the DNA leading to a single amino acid substitution may lead to a protein with altered structure and function. Webthe mutation is still at the DNA level (i believe its a single base pair mutation that causes the red blood cells to be sickle shaped). the reason why only half of the red blood cells …
