Answer:
Explanation:
Duchenne muscular dystrophy acts as a X-linked recessive disease. Which means the gene sits on the X chromosome, and you need two bad copies to show disease (for females) and one bad copy (to show in males).
Now from our knowledge, we know males are XY and females are XX. Males have only one copy of the X chromosome from their mother and one copy of the Y chromosome from their father, thus if they get the mutated version of the gene that causes this disease, they will get the disease. However, if a female has a mutated version of gene on one of the X chromosome, the other X chromosome could have a normal gene and that normal gene would take over and produce a normal phenotype/function.
Since, boys only have one X chromosome, if they get the mutated gene they will get the disease, whereas females have two X chromosome (so even if one copy is bad and the other is good, the good version can take over, however boys don't have this) thus mostly male children are affected by this.
The answer to the above question is Fatty acids.
<h3>What are
Fatty acids?</h3>
A fatty acid is a carboxylic acid with an aliphatic chain that is either saturated or unsaturated. This definition applies to chemistry, particularly biochemistry. The majority of naturally occurring fatty acids have an unbranched chain with 4 to 28 carbon atoms, which is an even number. In some species, like microalgae, fatty acids make up a significant portion of the lipids (up to 70% by weight), but in other organisms, they are present as one of the three main types of esters: triglycerides, phospholipids, or cholesteryl esters rather than in their solo form. Fatty acids are crucial nutritional sources of energy for animals in any of these forms, as well as crucial cellular building blocks.

Answer:
All of the above are true.
Explanation:
The prokaryotic organisms are the unicellular primitive organism which was formed in the primitive time when the conditions on the Earth were harsh.
The prokaryotes developed the metabolism to survive in the extreme conditions and were recognised as the archaebacteria. These bacteria can tolerate extreme condition like hot temperature called thermophilic conditions. These thermophiles can grow at higher temperature conditions than the eukaryotes.
The thermophiles are non-phototrophic organism as they do not utilize the light energy to produce energy as phototrophic organisms does.
Thus, all of the true is correct.
Answer:
In p53 pathways, 3 proteins which are mutate and cause cancer that proteins are:
1.BRCA2
2. p53 in Rb genes binds with deoxyribonucleic acid that stimulates another gene to produce a protein known as p21 that interacts with cdk2. When p21 is combined with cdk2 cell will not pass through to the next stage of cell division. This is Li-Fraumeni syndrome (when p53 causes cancer from parents to offspring)
3.BRCA1
The parent that transmits mutation in one of these genes has a 50% chance of inheriting the mutation. The effects of mutations in BRCA2 and BRCA1 are seen when the person's second copy of the gene is normal.
