How does disease affect the cell?
Sickle cell disease is a mutation in the gene that codes for hemoglobin, which causes the hemoglobin and the cell to become elongated and look like a sickle rather than its normal disc shape.
What are the chances of a person with huntigtons disease passing the disease to their offspring?
Huntington's disease is passed to offspring because it is a genetic mutation. Chromosome number four contains a gene called IT15 that codes for the amino acid in glutamine in the protein huntingtin. The nucleotide triplet that codes for this (CAG) usually repeats 11-34 times, but in a Huntington's gene it repeats 37-121 times. This "stutter" can lengthen when passed on through heredity, therefore increasing the chance that a person will have the disease.
What amino acid is codes for by this sequence after the mutation?

Is huntingtons a chromosomal or a genetic disease?
Hungtington's disease is a dominant mutation in the gene that codes for the protein 'Huntington' It only affects a single gene, the remainder of the chromosome is unaffected and therefore it is not a chromosomal abnormality
If a strand of DNA with the sequence TGA mutated to GCA would it be a silent or missense mutation?
Both a silent and missense mutation is a change in one nucleotide. However, a silent mutation still codes for the same amino acid, but a missense mutation codes for a different amino acid. This means that a silent mutation will have no affect on the resulting protein, but a missense mutation will. Still, it is not guaranteed that a a missense mutation will result in a disfunction of created protein, as long as it is not occurring in the activation site.
What causes Wiskott-Aldrich syndrome?
The syndrome is caused by a defect (mutation) in a specific gene called the WAS gene that normally codes for the protein named Wiskott-Aldrich Syndrome Protein (WASP).
A change in just one DNA base for the gene that codes for the protein?
Yes, as one base change can influence the protein structure that it codes for. For example patients suffering from Sickle Cell Anaemia.
What One example of a mutation that would not affect an organisms phenotype?
A Missense Mutation.It is a point mutation where the mutations alters the base sequence without changing the resulting function of the subsequent protein. This is usually when the mutation does not change the amino acid which the codon codes for.
How can a mutation in a gene lead new trait in an organism?
The mutated gene codes for a protein that cause a new trait
How can a mutation in gene lead to a new trait in an organism?
The mutated gene codes for a protein that cause a new trait
Which type of mutation results in abnormal acid sequence?
A point mutation causes a change in the amino acid sequence creating a new type of protein. The mutations are categorized functionally as nonsense, missense and silent mutations.
How can a mutation in a gene lead lead to a new trait in an organism?
The mutated gene codes for a protein that cause a new trait
