Genetic code is a sequence of 3 letter word, known to be one after the another along the length of the DNA.
Chromosome duplications and deletions frequently result in abnormal phenotypes or inviable gametes. Gene dosage is modified is a major contributor to this phenomenon.
In the field of genetics, we can define gene dosage as the quantitative measure or copies of a particular gene that is present in an organism. Abnormalities in the gene dosage at a particular location can cause severe damage to the resulting phenotype.
Gene dosage can lead to chromosome duplications if the copy number or gene product is more and it can cause deletions if the copy number or gene product is less. Such complications will result in abnormal phenotypes or inviable gametes. For example, in Down's syndrome, the person has a modification of the 21st chromosome as there is one extra 21st chromosome present. This leads to a variety of diseases and defects in the person.
Although a part of your question is missing, you might be referring to this question:
Chromosome duplications and deletions frequently result in abnormal phenotypes or inviable gametes. Which factor is a major contributor to this phenomenon?
a. Recessive diseases are unmasked by additional copies.
b. The genes are found in a novel arrangement.
c. Gene dosage is modified.

Methylphenidate refers to a CNS stimulant mainly used in the treatment of ADHD (attention deficit hyperactivity disorder) in children between the age of 6 to 12, adults up to the age of 65, and adolescents. It can also be used in the treatment of narcolepsy.
However, the application of the drug may also bring some side-effects with it. Some of the common side-effects related to medicine are decreased appetite, headache, hallucinations, sweating, fever, dizziness, increased heart rate, weight loss, and others.
In the given case, due to the application of the drug, the child is having hallucinations. Thus, in the given case, the nurse should recommend the client to report the manifestations as quick as possible, and discontinue the use of medicine.
The step at which the researchers would do at the end of researching Edna is to amplify the amount of DNA.
Option (d);
<u>EXPLANATION:</u>
- The term EDNA means Environmental DNA.
- Invasive species in the waterway are the waterborne plants and animals who can likely cause effects to the human as well as the environment.
- If researchers want to use eDNA to look for invasive species in the waterway, they will first collect a sample.
- After cutting DNA into pieces, DNA would be precipitated in each sample.
- And in the end, the amount of DNA would be amplified in each sample to understand how it would cause harm to the environment.
Answer:
ok I don't know the first one
2.nucleus is the power of cell and that make a new organisms and also it control all of cell activities.
3.green
4.ya b/c it is made or get in green pigment.
5.that is unspecified of plant cell and get in chloroplaste.
