Answer:The genome of an organism is inscribed in DNA, or in some viruses RNA. The portion of the genome that codes for a protein or an RNA is referred to as a gene. Those genes that code for proteins are composed of tri-nucleotide units called codons, each coding for a single amino acid.

Explain mutations and how they can cause genetic disease

nadya68 [22]

Answer:

A mutation is a change in a DNA sequence. Mutations can result from DNA copying mistakes made during cell division, exposure to ionizing radiation, exposure to chemicals
called mutagens, or infection by viruses. Germ line mutations occur in the eggs and sperm and can be passed on to offspring, while somatic mutations occur in body cells and are not passed on.

Mutation has been the source of many Hollywood movies, but it's really a simple process of a mistake made in a DNA sequence as it's being copied. Some of that's just the background noise that DNA copying is not perfect, and we should be glad of that or evolution couldn't operate. But mutation can also be induced by things like radiation or carcinogens in a way that can increase the risk of cancers or birth defects. But it's pretty simple; it's basically an induced misspelling of the DNA sequence.
That's a mutation.

When a variant alters a protein that plays a critical role in the body, it can disrupt normal development or cause a health condition. A condition caused by variants in one or more genes is called a genetic disorder. In some cases, gene variants are so severe that they prevent an embryo from surviving until birth.

NemiM [27]

Answer:

Two proteins that are present inside the same cell perform different functions because both proteins have different amino acid composition.

Explanation:

Amino acid is the building blocks of protein. Different proteins perform different functions due to their composition. These proteins are formed by the instructions given to the ribosome of the cell.

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.
