DNA"DeoxyribonucleicAcid"​

Biology

Answer:

Details about DNA are given in the explanation section. Hope it will be helpful for you.

Explanation:

DNA, or deoxyribonucleic acid, is the hereditary element in humans and almost all other organisms. Nearly every cell in a person’s body has the same type of DNA. Most DNA is found in the cell nucleus (nuclear DNA), but a small quantity of DNA can also be found in the mitochondria (mitochondrial DNA or mtDNA).

The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same type in all people.

DNA bases pair up with each other, A with T and C with G, to form units that are called base pairs. Each base is also attached to a sugar molecule and a phosphate molecule.  A base, sugar, and phosphate are called a nucleotide. Nucleotides are arranged in two long strands that form a spiral called a double helix.

A valuable feature of DNA is that it can replicate, or make copies of itself. Each strand of DNA in the double helix can serve as a pattern for duplicating the sequence of bases.

Masja [62]

Answer:

The correct option is <em>C. Non-genetic factors can influence expression.</em>

Explanation:

Non- genetic factors can be described as factors other than genetic makeup. These factors include environmental factors and factors arising from the lifestyle of an organism.

Certain studies have shown that both the genetic as well as the non- genetic factors play a role in the development of certain characteristics.

In the above-mentioned scenario, both the monozygotic twins have diabetes but one of them is affected 70% of the time due to his lifestyle. The person might be consuming more sugars and alcohol.

Dr. Charles is using fMRI when she uses strong magnets to track changes in the brain's blood-oxygen levels.

Functional magnetic resonance imaging or (fMRI) is a techique used to measure brain activity by detecting changes associated with blood flow. When an area of the brain is in use, blood flow to that region will increase.

The patient, a 12-year-old boy, shows several areas of tooth decay: #3 mesial, #12 occlusal, #20 occlusal, and #30 on the occlus
yawa3891 [41]

Since the amount of decay is too much, the dental assistant should respond by advising the mother of the patient to reduce the quantity of sugary food intake and to enhance oral hygiene.

A dental assistant is an individual that are usually certified to assist dentists during dental treatment procedures.

During a dental procedure, they help to perform the following tasks:

  • preparing patients for the treatment,
  • passing dentists instruments and other materials, and
  • keeping patients' mouths dry and clear using suction and other devices.

Tooth decay is the formation of a hole through the tooth cavity.

Tooth decay can occur in several areas when there is poor oral hygiene and excess intake of sugary foods.

When sugary food is taken in excess without proper oral hygiene, it reacts with plaque bacteria in the mouth producing acids.

The acid then dissolves your enamel slowly, creating the cavities in your teeth.

Therefore, the dental assistant should respond by advising the mother of the patient to reduce the quantity of sugary food intake and to enhance oral hygiene.
