Why is circular doubled stranded DNA the preferred

Verizon [17]

Answer:

An example of circular double-stranded DNA molecules is the mitochondrial genomes that are 16,569 bp long and are present as one or more copies within all mitochondria of a cell. Thus mitochondrial DNA (mtDNA) is present in hundreds to thousands of copies per cell.

mtDNA is maternally inherited, so siblings will share the same DNA as their mother but not that of the father.

mtDNA is present in cells at a high copy number.

mtDNA is typically sequenced in the two hypervariable regions.

Explanation:

mtDNA is useful primarily for identity testing. mtDNA analysis may become essential when only a distant relative is available for a reference specimen.

In database searches of autosomal STR data from unidentified human remains or missing person relatives, the algorithms for the search often produce several potential matches, and mitochondrial DNA analysis is needed to identify the true match.

Deficiency wise, pathological alterations of mtDNA may occure and, it fall into three major classes: point mutations, deletion-duplications and disordered mtDNA content, that is, copy number.

On how to overcome these deficiency, the maintenance and integrity of the mitochondrial genome depend on several poorly understood factors.

Theoretically, defects in any of the proteins involved in mtDNA replication might affect mtDNA copy number. MtDNA replication is also highly dependent on mitochondrial dNTPs supply, and mutations in several genes involved in mitochondrial dNTP synthesis may therefore cause MDS (Mitochondrial DNA depletion syndrome).

Roles of bones in bony fish include which of the following?

Rina8888 [55]

Answer:

D All of the above

Explanation:

Like our bones, bones in fish can provide general protection and support to their body.

(Fun fact, jellyfish do not have bones, so when they are out of the water, they loses their bell shape structure and looks more like a flat piece of jelly. But fish tends to look the same when it is in water and out of water.)

The bone is also where the muscles will attach to, which allows for movement.

(Imagine our fingers, the muscles in our fingers are attached to our bones, which allows us to do things like typing.)

Bones can also protect the fish's brain.

(Brain can be very fragile and soft, so having a hard structure around it can protect the brain. It's kind of similar to protecting the liquid egg in an egg shell.)

Modeling the Calvin Cycle Exploration

galina1969 [7]

Explanation:

The process of photosynthesis is energy-storing because the process converts light energy into chemical energy, which is stored in the bonds of glucose.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

Further Explanation:

Photosynthesis is a chemical pathway, integral to plant and other primary producers producing energy. Energy is produced from light, water and carbon dioxide in the form of glucose molecules while the oxygen is emitted.

Photosynthesis, which occurs in several complex steps, is a rate-limited reaction, depends on several factors including concentration of carbon dioxide, ambient temperature, and light intensity; energy is recovered from photons, i.e. light particles, and water is used as a reducer. For those removed from photosystem II, water supplies the chlorophyll in plant cell with replacement electrons.

Therefore, water (H2O) split into H+ a by light during photolysis into H+ and OH-acts as a source of oxygen along with functioning as a reducing agent; it reduces the molecule NADP to NADPH by providing H+ ionsand produces molecules of the energy storage moleciule ATP through an electron transport chain. This occurs in the thykaloids, where pigment molecules like chlorophyll reside.

Later, in dark reactions, NADP and NADPH are used in the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules. These hold energy in their bonds, which can be released in respiration in the mitochondria.

Glucose production occurs after G3P production- a molecule of G3P, goes to the cytoplasm from the cycle, to form complex molecules and simple sugars like glucose.
