Answer:
The disease is autosomal dominant.
Explanation:
Huntigton's disease is an autosomal dominant disease because the allele for this disease is present on an autosomal chromosome and the person with even one mutated allele (H) can develop the disease even if he has one normal allele (h) too. If a person is affected with Huntigton's disease, there are 50 percent chances that the children will also suffer from the disease.
For example: A father is suffering from Huntigton's disease but mother is normal. Let us see how it will be passed to kids.
P1: Hh : hh
Gametes: H : h: h: h
Offspring: Hh: Hh: hh: hh
50% : 50%
Therefore, 50 percent chances are there that the kids will have disease even if only parent suffers from it.
Answer:
AGU-CUA
Explanation:
An mRNA sequence is made using a DNA sequence as a template. The sequence is dictated by complementary base pairing.
DNA uses the bases A, T, C and G. A is complementary to T and G is complementary to C.
RNA uses the bases A, U, C and G. A is complementary to U and G is complementary to C.
When transcribing DNA to RNA:
- C is paired with G
- G is paired with C
- A is paired with U
- T is paired with A
Therefore, TCA-GAT is transcribed to AGU-CUA
The answer to this question would be: Stomach(gaster), HCl
Protein digestion happens in the stomach. The stomach will secrete the acid which was HCl to kill bacteria inside food and denatures the protein. The acid also activates pepsin enzyme and in turn, will digest the protein into smaller amino acids.
