First of all, hemophilia is an x-linked recessive and recessive disease. So it's a genetic disease.
- Therefore, there is no possibility of snatching it from his son. It can come from mom or dad. If the mother and father do not have this disease, as in the question, the mother carries this disease recessively. If it was a girl, she would be less likely to get the disease, as she would have to inherit the genotype of this disease from both the mother and the father. however, since her children are boys, she received the disease gene from the mother's recessive gene region. Therefore, the boy has hemophilia in the XhY genotype.
What we eat (our environment) and genetic variables come together in epigenetics.
Describe epigenetics.
A branch of genetics called epigenetics investigates how variations in the environment might affect how genes are expressed.
DNA methylation, histone alterations, and non-coding RNA pathways are examples of epigenetic mechanisms.
In conclusion, epigenetics is the fusion of genetics and environment.
Hypothesis contributed to the mistaken idea that protein is the genetic material because, with its 20 different amino acids, protein structure could be more variable than that of c.
<h3>What is DNA?</h3>
- Deoxyribonucleic acid is a kind of DNA.
- All known animals and many viruses contain genetic instructions in the form of a polymer called DNA, which is made up of two polynucleotide chains that coil around one another to form a double helix.
- Among the four major categories of macromolecules—along with proteins, lipids, and complex carbohydrates—nucleic acids are one of the four that are essential for all known forms of life (polysaccharides).
<h3>How does DNA get created?</h3>
- The chemical building blocks of DNA are called nucleotides.
- These constituents consist of one of four different nitrogen bases, a phosphate group, a sugar group, and a sugar group.
- DNA strands are built from chains of nucleotides that are bonded together with the phosphate and sugar groups swapped out.
