what is dna ? and what is the purpose of dna
Answer:
Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and function of living things. All known cellular life and some viruses contain DNA. The main role of DNA in the cell is the long-term storage of information.
Explanation:
-Eijiro <3
First, it has to be able to make copies of itself because you're making new cells all the time and your cells have to have a copy of your DNA so it has to do what we call replication.
It also has to store all the information about your body as far as your body chemistry, your proteins, your amino acids, and all the things that make you.
One more very important job of DNA is that it's responsible for this process called protein synthesis which is the process in which cells make proteins. So every piece of your body from your fingernails, your eyeballs, and many other things are made up of proteins, proteins are the building blocks of you and the DNA determines the shape and function of your proteins. You think of DNA as a set of instructions on how to make the proteins that make you.

What is the relationship between mutation, the cell cycle, and cancer? Select all statements that apply.
A. Mutated genes typically allow cells to respond to checkpoint proteins that halt the cell cycle, thus avoiding formation of tumors.

What are disadvantages of the "Aoudad"?
PLEASE ANSWER ASAP!!
Answer:
Anecdotal reports suggest aoudad out compete native big game species for food, water, and cover as well as act as a disease reservoir on Texas landscapes.

In humans, as well as in many other animals and some plants, the sex of the individual is determined by sex chromosomes.
The sex chromosomes are one pair of non-homologous chromosomes. XX represents a female, while XY represents a male
When a gene for a specific trait is attached to the X or Y chromosome, we say it is sex-Linked, and when it is attached to the X
chromosome, we say it is X-linked. Alleles for these linked traits, such as hemophilia on color blindness, crosses, may be
recessive or dominant
This is one possible cross (above) for the X-linked condition known as hemophilia. Which pair of parents is most likely to have a
hemophiliac daughter?

What is the effect of inputting stem cells instead of body cells into the original system?
Explanation:
Stem cell research indicates that s.cells are cells that are not fully developed; in turn if researchers inject a patient with type 1 diabetes into the pancreas the result is that the pancreas produces it's own insulin eliminating the chances of spikes in the blood sugars of the patient & also long term effects of high blood sugars that effect all vital organs & nervous system.
Researchers were also using stem cells to limbs that were amputated or damaged resulting in the limb regenerating itself.
I have seen a mouse that had a human ear attached to its body.
Researchers were ordered by our government to cease the experiments because pharmaceutical companies were making more $$ on medicines to supposedly help diabetics or veterans to live a normal life..

Answer:
Roughly n = 171
Explanation:
512/3 = 170.666666667
the round it to the nearest tenth which is 171, So N is roughly 171
Hope this helped
Explanation:
Given
n³ = 512
Putting cube root on both sides we get
³√n³ = ³√8³
Therefore n = 8

¿Que celula está compuesta por tres partes importantes que son la membrana celular, el citoplasma y el núcleo celula?
Answer:
Células eucarióticas
Explanation:
Todas las células poseen membrana celular, encargada de la protección de la célula de agentes externos a ella, y del intercambio de sustancias entre el interior y el exterior celular, entre otras funciones.El interior de la célula eucariótica tiene un citoplasma con organelas y citoesqueleto. Las organelas tambien estan rodeadas por membranas y cumplen diversas fnciones cada una, que se acoplan para el correcto funcionamiento de la célula. Finalmente, a diferencia de las céllas procariotas, las eucariotas tienen un núcleo que protege el material genético de la célula. En núcleo tiene una doble membrana que lo separa del citoplasma.what are the two biggest planets on earth

Read the following scenario and student explanations. Then, respond to the following questions.
A 7th grade teacher had students construct an explanation comparing and contrasting Plants and Fungi. The explanations of two students are below.
Student A: Plants and fungi are similar in that organisms in both kingdoms have the following characteristics: grow from the ground, have a nucleus, are unicellular and multicellular, and have a cell wall. However, they differ because plants can make their own food, but fungi cannot.
Student B: Plants and fungi have some characteristics in common such as being multicellular, having a nucleus and a cell wall. But, fungi are different from plants because they get their nutrients from other organisms, but plants make glucose as their food.
