There are two main types of driver genes: mut-driver genes and epi-driver genes. Mut-driver genes are genes that are mutated in such a way that they cause cancer. Epi-driver genes are genes that are not mutated, but that are overexpressed in cancer cells.

Passenger gene mutations are mutations that are not thought to play a role in causing cancer. However, driver genes can have passenger gene mutations. For example, a driver gene may be mutated in such a way that it causes cancer, but it may also have a passenger gene mutation that does not contribute to the cancer.

Some possible solutions to control the spreading are Invasive Species :

Any non-native species that significantly alters or disrupts the ecosystems it colonizes is referred to as an invasive species, also known as an introduced species, alien species, or exotic species. Such species may migrate naturally to new areas, but they are frequently brought in by the activities of other species.

On the basis of the principle of complementary base pairing, you would expect the percentage of adenine in an individual’s DNA to be equal to the percentage of thymine.

The expression that denotes the complementary base pairing makes reference to the arrangement of nucleotides in the double helix of DNA.

In DNA, Adenine or A always pairs with Thymine or T (thereby the amount of A is equal to T), while Guanine or G always pairs with Cytosine or C (thereby the amount of G is equal to C).

Base complementarity is one of the most important rules in genetics and it is used to estimate nucleotide proportion, a process associated with gene expression in CpG islands.

In conclusion, on the basis of the principle of complementary base pairing, you would expect the percentage of adenine in an individual’s DNA to be equal to the percentage of thymine.

Answer:

The sneeze centre sends signals to the parts of your body that need to work together to help you sneeze. Your chest muscles, diaphragm, abdominals, vocal cords and the muscles in the back of your throat all work together to help you expel the irritant.

Explanation:

Achondroplasia is an inherited conditions that impedes long bones growth resulting in dwarf phenotype. The mode of inheritance is complete dominance, expressing a phenotypic ratio = 3:1.

Achondroplasia is a congenic condition genetically determined. Individuals expressing this condition do not have normal bone development. They are short in height, with short extremities and macrocephaly.

A mutation in the gene FGFR-3 is responsible for this condition, affecting mainly long bone growth. Normal parents can have a dwarf son or daughter.

The inheritance pattern of this condition is complete dominance, meaning that an autosomal dominant allele is responsible for achondroplasia expression.

If two individuals with achondroplasia have at least one normal child it means that both parents are heterozygous for the trait, and both of them transmitted the recessive allele to the normal child. Let us see,

We will name,

Cross: two individuals with achondroplasia

Parentals)  Aa   x    Aa

Gametes) A   a      A    a

Punnett square)  A     a

                      A   AA   Aa

                       a  Aa     aa

F1) 1/4 = 25% of the progeny is expected to be homozygous dominant AA and express achondroplasia

    2/4 = 1/2 = 50% of the progeny is expected to be heterozygous Aa and express achondroplasia

     1/4 = 25% of the progeny is expected to be homozygous recessive aa and express the normal phenotype (wild type).

The phentoypic ratio is 3:1.

Now let us talk about the ratios,

4 possible genotypes -------------------- 3 individuals among the progeny

3 dwarf genotypes ------------------------X = (3 x 3) / 4 = 2.25 ≅ 2

1 wild type genotype --------------------- X = (1 x 3) / 4 = 0.75 ≅ 1

The phenotypic ratio of the progeny approximates 3:1.

The phenotypic ratio of 3:1 is typical of complete dominance.

The mechanisms of antigenic variation are:-

1. mutation 2. recombination 3. gene switching

One of the methods of antigenic escape, antigenic variation or antigenic alteration refers to the process by which an infectious agent, such as a protozoan, bacterium, or virus, modifies the proteins or carbohydrates on its surface and evades a host immune response. It has to do with a phase shift. The pathogen can re-infect previously infected animals thanks to antigenic diversity, which also helps it dodge the immune response in its present host. Recognition of the antigens carried by the virus, which are "remembered" by the acquired immune response, provides the basis for immunity to re-infection. If the pathogen's main antigen can be changed, the acquired immune system of the host can be circumvented.

ice floating on the surface of a body of water insulate the water in a way that the  ice layer insulates the water below it  by  insulating the  top of lakes and seas, allowing it to stay liquid, which allows the life within it to survive.

but sometimes it has negative impact on sea organism because When ice forms across the surface of a lake, it seals off the water from atmospheric oxygen exchange and blocks out much of the light that is necessary for aquatic plants and phytoplankton to produce oxygen within the lake. Throughout the winter oxygen levels in the lake slowly decline. so organism may face difficulties to survive .

If ice didn't float it would form at the bottom of a body of cold water rather than the top. The water would continue radiating heat away from its surface and so would get colder and colder until the water and everything in it had frozen solid from the bottom up. and organisms will die.

According to the law of supply and demand, the price of copper is directly related to the rate of its production.

The quantity of a good supplied, or the amount owners or producers offer for sale, is said to increase as the market price increases and decreases as the price decreases according to the law of supply. In contrast, the law of demand (see demand) states that when a good's price increases, less of it is sought and vice versa.

A basic tenet of economics is that when there is more supply than demand for an item or service, prices decline. Prices typically increase when demand outpaces supply. When demand is constant, there is an inverse relationship between supply and prices of products and services.

The link between supply and demand is crucial because it helps to establish the costs and availability of the majority of goods and services in a given market. The interplay between supply and demand eventually balances out in accordance with the tenets of a market economy.

The hermaphroditic nematode Caenorhabditis elegans has a mapped somatic lineage that is mostly invariant, yet during larval and adult stages, germ cells continuously multiply in a stem cell niche.

Early embryonic cell divisions happen quickly and don't have G1 or G2 phases. The G1 phase only appears late in embryogenesis in a small proportion of actively dividing cells, according to the existing evidence, and it is first noticed at gastrulation.

Different DNA replication rates, which are partly explained by the variable activation of the DNA-replication checkpoint, result in differences in the time of early embryonic cell cycles between lineages.

The formation of post-embryonic cell lineages is closely controlled, with cycles of cell division starting and ending at particular times during larval development. Although changes to the heterochronic pathway, which controls the sequence of larval programs, might indirectly change the time of cell divisions, the extrinsic or intrinsic cues that regulate the timing of initial cell-cycle entry remain unknown.
