Huntington’s disease: Huntington’s disease is a disease in which certain parts of the brain waste away; symptoms usually begin l

neonofarm [45]

Answer:

Regarding Huntington's disease, it can be said that it is an inherited disease with an autosomal dominant character, so it is enough that one of the children inherits one of these characters to manifest this neurodegenerative disease, it is considered that the pattern is usually 50% of the total of children of sick parents can suffer it, however if both parents are carriers the number rises leading to 100% of the children affected, on the contrary if no parent has the dominant gene and are homozygous recessive, neither your children will suffer the disease

The possibilities are the following:

Parent 1, inheritance pattern: Hh * hh, the possible gametes for this cross-linking are H, H, h, h, offspring; Hh, Hh, hh, hh 50% of the children could be sick

Parents 2, inheritance pattern: hh * hh, the possible gametes for this cross-linking are h, h, h, h. the offspring will be; hh, hh. no sick child

Parent 3, inheritance pattern: HH * HH, the possible gametes for this cross-linking are H, H, H, H, the offspring will be HH, HH, all children may be sick, 100%

parents 4, inheritance pattern: Hh * Hh, the possible gametes for this cross-linking are h, H, h, H. the descendants will be HH, Hh, Hh, hh 50% of sick children

Parents 5, inheritance pattern: Hh * hh, the possible gametes for this interbreeding are H, h ,, offspring will be Hh all sick children

Parent 6, inheritance pattern: Hh * Hh the possible gametes for this cross-linking are H, h, the descendants will be Hh, the heterozygous descendants will have the disease.

Mrna,amino acids,type of mutation

Leya [2.2K]

Answer:

mRNA: 3' AUG-AAU-GCU-GCC-GGU-GA-5'

amino acids : methionine, asparagine, alanine, arginine, proline

type of mutation: deletion, missense

Explanation:

The mRNA sequence is complementary to the DNA sequence. A always pairs with T, C always pairs with G. Except this is an RNA sequence not a DNA sequence, so T is replaced with U.

The mRNA sequence is translated into an amino acid sequence based on the triplet code. The triplet code for this sequence is shown in the attached picture. Each triplet signifies a specific amino acid. The codon can be identified from the table and placed in sequence. We can see that the new DNA strand has caused a new amino acid sequence. It has also left us with an incomplete sequence, as GA cannot signify an amino acid.

The type of mutation is a single base deletion. We can see that the base C is missing from the 9th amino acid in the original strand. As you can see, this has an ongoing affect on all the bases in the rest of the sequence, as it changes the way the sequence is organised into codons. This results in a missense mutation.

An imaginary species of bears, fur color can be purple or gold. Gold is the dominant trait. How would the bear look if the gene

BARSIC [14]

Answer:

Explanation:

Assume Gold trait =P ,

Purple= p,

Given:

Gold (P) is dominant over purple(p), so P is dominant over p.

If the bear is homozygous pp ( recessive) then bear will look purple,

If the bear is heterozygous Pp, then bear will look gold,

If the bear is homozygous DD( dominant), then the bear will look GOLD,
