Answer:

DNA mutations cause cancer or an inability for proper function of the immune system.

Explanation:

DNA is our blueprint, so if something is wrong on the blueprint, then our body will "collapse" like a building (well not always). Let's say, the gene for immune system function is mutated and comes out wrong. That person might not be able to make white blood cells which fight off sickness. Other mutations can also cause cancer, which is a really bad form of sickness.

What are the effects that enzymes can have on substrates

Burka [1]

In chemical reactions involving enzymes, the substrate proteins are huge molecules that will only react with each other if they're aligned just the right way. If they are permitted to interact with the enzymes present, the won't collide and react often enough for the reaction to do any good.The enzymes align the molecules, basically acting like "molecule shepherds," showing them the way they need to react.This speeds up the reaction greatly, making things like digestion possible. Hope this is helpful

Thale cress is a plant that is genetically engineered with genes that break down toxic materials. Which type of organism is desc

MArishka [77]

The correct answer for the given question above would be option B. Thale cress is a plant that is genetically engineered with genes that break down toxic materials, so this would be a transgenic type of organism. By definition, transgenic organisms undergone genetic engineering wherein genes of a particular specie is modified or transplanted into another. Hope this helps.

The blood Group of Mother is O. The Blood Group of the Child is B. Man Exonerated If He to Blood Group?

aalyn [17]

Answer:

If the mother's blood type is O, and the child's blood type is B, a man would be exonerated from paternity if he has blood type A or O.

Explanation:

In the above case, if a mother has blood type O and her child has blood type B, a man can be exonerated from paternity only if his blood type is A or O, and responsible if he is type B or AB.

The blood type is defined by the presence of surface antigens in the red blood cell, called A and B. The presence of each antigen is determined by a gene present on the parental chromosomes.

Blood type A corresponds to the presence of gene A, and its genotypic expression can be A/A or A/O.
Type B blood, whose genotype is B/B or B/O, is due to the presence of a gene containing the B antigen.
AB blood —due to codominance— has one gene for A and another for B, with genotype A/B.
Blood type O, characterised by the absence of surface antigens, behaves like a recessive trait, which only manifests itself in the absence of surface antigens A and B. The genotype is O/O.

By making a hypothetical crossing between mother and man, one can observe why he can be exonerated.

Man with blood type O

♂ O|O

♀ O|O

Alleles O O

O O|O O|O

The only possibility, in this case, is to have children with type O blood. No chance of children B.

Male with blood type A

♂ A|O

♀ O|O

Alleles A O

O A|O O|O

In this case there is a 50% chance that the children will be blood type A and 50% chance that they will be O. No chance of children B.

In the case of a man A|A the result is 100% probability of children A|O, and no probability of children B.

So, a man with blood types A (any genotype) and O, can be exonerated from paternity, since it is impossible for him to have a child of blood type B, when the mother is of blood type O.
