It depends on where you live, if daylight savings time is in your state or not.
To make amino acids, proteins, and DNA. When organisms die, their bodies decompose bringing nitrogen into the soil on land or into ocean water.
The correct answer is: In trisomy there would be one extra chromosome; in a duplication, the number of chromosomes would be normal, but one chromosome would have two copies of a portion of the chromosome.
Trisomy is a type of polysomy (chromosome aberration with extra number of chromosome/s) and also type of aneuploidy (an abnormal number of chromosomes).
Instead of the normal two (one from mother one from father) chromosomes, people with trisomy have three chromosomes. This condition occurs when chromosome pairs fail to separate properly during cell division.
Duplication, on the other hand, usually refers to a region of DNA that is being duplicated. This condition occurs as products of several types of errors in DNA replication and repair machinery.
