Which condition or statement exemplifies the concept of genomics rather than genetics?
ValentinkaMS [17]

Answer:

A. The gene for insulin is located on chromosome 11 in all people.

Explanation:

Genomics includes the study of the content, organization, function and evolution of genetic information in a complete genome. The genomic term is relatively recent. It is considered that it was coined by Thomas Roderick, in 1986, to refer to the subdiscipline of genetics dedicated to the study of cartography, sequencing and analysis of the functions of complete genomes.

Insulin is formed as pre-proinsulin of the precursor protein. This is encoded by a 14kb series in the INS gene. In most animals including humans, a single gene for insulin is found. The human gene is located on the short arm of chromosome 11 at position 15.5 (11p15.5).

The insulin gene has recently been decoded in its complete form in genomic studies. The human and rat insulin genes have been reproduced and the DNA has been sorted. It has been shown that mouse and rat insulins are identical and have similar gene series and organization, which are similar in genetic series to humans.

During meiosis, a defect occurs in a cell that results in the failure of microtubules, spindle fibers, to bind at the kinetochor
mario62 [17]

Answer:

The resulting cells will not receive the correct number of chromosomes in the gametes, a condition known as aneuploidy.

Explanation:

Formation of functional microtubule spindle fibers and their attachment to kinetochores of chromosomes is required to ensure their alignment st the cell's equator during metaphase. During anaphase, shortening of these microtubules pulls the chromosomes to the opposite poles. These events ensure the distribution of the correct number of chromosomes among the daughter cells. The presence of defective microtubules would not allow proper distribution of chromosomes to the daughter cells and would result in the presence of an abnormal number of chromosomes (aneuploidy).

What is the common component of air pollution?
Ghella [55]

The common component of air pollution is particulate matter (PM). This is a complex mixture of extremely small particles and liquid droplets.

 The major components of PM are sulphates, nitrates, ammonia, sodium chloride, black carbon, dust particles and water. PM comes from dust , soot, smoke, industry and vehicle exhaust as well as complex chemical reactions with other pollutants.

 Burning of fossil fuels produces sulphur dioxide . It is a colorless gas that pollutes the air and can cause health problems affecting the respiratory system.
