Answer:

Hemophilia A is caused by disruptions or changes (mutations) of the F8 gene located on the X chromosome. Approximately 70% of cases are inherited as an X-linked recessive trait. In the remaining 30%, cases occur spontaneously (i.e. new mutation) without a previously family history of the disorder.

bixtya [17]

Answer:

Explanation:

해파리 (cnidarians) have a worldwide distribution. Despite most being harmless, some species may cause local and also systemic reactions. 처치 of 해파리 envenomation is directed at: alleviating the local effects of venom, preventing further nematocyst discharges and controlling systemic reactions, including shock. In severe cases, the most important step is stabilizing and maintaining vital functions. With some 차이점 between species, there seems to be evidence and consensus on oral/topical analgesics, hot water and ice packs as effective painkillers and on 30 s application of domestic vinegar (4%–6% acetic acid) to prevent further discharge of unfired nematocysts remaining on the skin. Conversely, alcohol, methylated spirits and fresh water should be 조심스럽게 avoided, since they could massively discharge nematocysts; pressure immobilization bandaging should also be avoided, as laboratory studies show that it stimulates additional venom discharge from nematocysts. Most 처치 approaches are presently founded on 상대적으로 weak evidence; therefore, further research (especially randomized clinical trials) is strongly recommended. Dissemination of appropriate 처치 modalities should be deployed to better inform and educate those at risk. Adequate signage should be placed at 바닷가 to notify tourists of the jellyfish risk. Swimmers in risky areas should wear 보호 장비.

Your scan of Lucy's ADA gene showed a mutation in the active site. Why was this mutation not a problem?

notsponge [240]

Answer:

it does not disturb the overall function of the active site

Explanation:

The gene mutation will not have an effect on the active site. This is because the mutation affects the non-essential amino acid or protein in the molecule. This causes the molecule to be in the same state and shape it was. In addition, the Quaternary protein structure has many proteins on the active site. Hence the mutation will not be significant and detrimental to the overall structure and function of the molecule.
