A mutation affecting the HBB gene may result in the production of haemoglobin S (HbS), leading to sickle cell disease, thus classifying this mutation as harmful. Conversely, individuals who carry one copy of the mutant allele exhibit resistance to malaria, which renders this mutation beneficial. A mutation found in the EYC3 gene is regarded as neutral since changes in eye color can have beneficial or harmful outcomes. A mutation in the CFTR gene is deemed harmful, as it generates a malformed CFTR protein, disrupting the balance of Cl and fluids and causing mucus to thicken in various organs, ultimately impairing function. Furthermore, a mutation in the LRP5 gene leads to high bone mass and may result in various bone density-related conditions, categorizing this mutation as harmful.
This qualifies as a scientific inquiry since an experiment could be designed to examine the hypothesis.
Answer:
100 units
Explanation:
The parent cell holds 200 units of DNA. During the process of cell division, this amount is distributed between the resulting daughter cells, with each cell obtaining half of the DNA present in the original cell.
As mitosis yields two daughter cells, each one will receive 100 units of DNA.
Regardless of the external conditions of the cell
The discovery of numerous new species made it unfeasible to organize them all according to a hierarchy that reflected their complexity.
