c. strand specific nicks
d. double-strand breaks

Please help!!

Answers

Answer 1

The statement DNA polymerases cannot initiate synthesis of a new DNA strand; they can only add bases to an existing strand is TRUE about DNA replication while the mismatch repair mechanism is initiated by strand-specific nicks.

What are DNA polymerases?

DNA polymerases are specific enzymes that add nucleotides during the semiconservative replication of DNA, which involves the synthesis of a new DNA strand for each daughter DNA molecule.

Moreover, the mismatch repair mechanism refers to the pairing between nucleotide sequences other in DNA and double stranded RNA (dsRNA) is initiated by strand-specific nicks in order to repair a given nucleotide sequence.

Therefore, with this data, we can see that DNA polymerases are essential enzymes used by the cell in order to synthesize a DNA strand during the process of semi-conservative DNA replication, which occurs before the process of cell division and may involve mismatch repair mechanisms.

The relationship among genes, DNA, and traits can be defined as, Traits are determined by genes, which are composed of DNA.

A trait is a phenotype that is expressed in the individual. Genes are segments of DNA that are responsible for the expression of a particular phenotype or physical characteristic. Genes code for protein through RNA   resulting in the expression of a character.

DNA is the genetic material that has coding and non-coding part. The coding sequence is also referred to as the gene. The coding part of DNA undergoes translation resulting in the formation of RNA, then RNA undergoes translation to form protein and the protein is expressed as a trait.

pleasse help!! Explain how the structure of a leaf is designed perfectly for photosynthesis? 15 points!

Answers

Leaves have cells in the mesophyll (the tissue between the upper and lower epidermis) that have a specific job of carrying out photosynthesis, especially on a large scale. They’re capable of this because leaves possess something known as chloroplasts — chloroplasts are found ONLY in plant cells and are responsible for the conduction of photosynthesis. Also, the bigger the leaf, the more cells, the more chloroplast, which makes sure no matter how big the leaf is it can still carry out photosynthesis.

Based on the incoming signals, appropriate ____________ to skeletal muscles corrects the body's position in space.

Answers

Based on the incoming signals, appropriate motor-neurons to skeletal muscles corrects the body's position in space.

The cells that make up the nervous system and the brain are known as neurons. They are the basic signalling components that enable us to move our muscles, sense our environment, think, create memories, and do a lot more. Based on this signalling, motor neurons to skeletal muscles corrects the body's position in space.

All of our muscle motions are thus directly controlled by motor neurons, which send signals from the spinal cord to skeletal and smooth muscles (like those in your stomach).

The most prevalent type of nerve cell "body plan" for motor neurons is multipolar, with one axon and multiple dendrites on each cell.

Answers

Sodium ions bind to the pump and a phosphate group from ATP attaches to the pump, causing it to change its shape. In this new shape, the pump releases the three sodium ions and now binds two potassium ions. Once the potassium ions are bound to the pump, the phosphate group detaches. This in turn causes the pump to release the two potassium ions into the cytoplasm.

The ATP here changes the shape of the protein.

What is temperature change?

During summers, the sunrays hit Earth at a very steep angle. The sunlight does not spread out as much, thus increasing the amount of energy which is hitting any spot. Also, the long daylight hours allows Earth time to reach the warm temperatures.

The daily air temperatures at Earth's surface are in control of the incoming and outgoing energies.

Write a brief letter to a local coalition of cattle ranchers explaining why the members should begin raising cattle on open grasslands instead of in feedlots.

Answers

Being rising cattle on open grassland instead of feedlot is really important.

Describe a feedlot.

In intensive livestock farming, a particular kind of feeding operation is called a feedlot.

The basic goal of a feedlot is to feed cattle and help them gain significant body fat over the course of five months.

Describe grassland.

It is a region where a practically continuous layer of grasses rules the vegetarian.

Why is it vital to raise cattle on open grassland rather than in a feedlot?

There are many drawbacks to feedlots, such as the constant standing of cattle in their own feces and urine in a tight, cramped environment.

E levels may be higher in cattle whose diets are high in corn.

Cattle living in feedlots experience stress since their heavy corn-based diet results in constant health problems. Its flooring is subpar, the cattle suffer from a lack of sleep, and there are no opportunities for them to exercise or get enough rest.

On the other hand, cattle prefer open grassland since it is considerably sweeter.
