DNA is negatively charged. When an electrical current is passed through a gel, the DNA is repelled by the nearby negative current and pushed across the gel towards the positively charged side.
Explanation:
Electrophoresis has become a standard molecular biology technique. This technique is based on the use of a constant-uniform electric field that enables the separation and identification of DNA fragments with different lengths, which form bands in the electrophoresis gel. Electrophoresis can be used to analyze not only DNA, but also RNA and proteins. During electrophoresis, the fragments of DNA that are negatively charged will migrate towards the positively charged electrode, where the duration of this movement will depend on the size of the DNA fragment, as well as of the pore size in the gel.

C. they store water
D. they store ribosomes
Answers
Answer:
They store water
Explanation:
The unique function of vacuole in a plant cell is the storage of water.
FUNCTION OF VACUOLE:
Vacuoles are organelles bound by a membrane and present in both animal and plant cells. They are fluid-filled spaces in the cytoplasm of a cell. Vacuoles are present in the central position of a plant cell, where it occupies more than half of the cell's content. Vacuoles help plant cells to store water and maintain turgidity and homeostasis in the cells of plant.Therefore, vacuoles help the plant cell to store water.

What is asexual reproduction?Asexual reproduction is a form of reproduction in which only one parent is involved in the production of offspring.
Asexual reproduction does not require the fusion of the male and female gametes to form an embryo which then develops into a mature offspring.
Hence, asexual reproduction is the most dominant form of reproduction in living organisms as it requires less energy or time for the production of offspring.
Some forms of asexual reproduction are:
vegetative reproduction - the offspring is produced from a part of the parent as an offshootSpore formation - reproductive cells are produced which are then dispersed and grow during favorable times.Learn more about asexual reproduction at: https://brainly.com/question/12176249

2. Light chain is the small polypeptide subunit of an antibody (immunoglobulin).
3. Variable region is the ends of the light and heavy chains
4. Constant region is determines the mechanism used to destroy antigen.
5. antigen binding site is the part of an antibody which recognizes an antigen, the antigen-binding site of an antibody.

c.They each contain different combinations of the parent cell’s genetic material.

Answers
Answer:
a.They each contain a nucleus.
b.They each are smaller than the parent cell, but will grow to a full size.
c.They each contain different combinations of the parent cell’s genetic material.
Explanation:
When a Mother cell divides itself asexually or sexually (typically through the process of Binary Fission or Meiosis or Mitosis) the daughter cells formed inherit the contents and the organnels of the Parent Cell almost equally. This includes the Nucleus and Cytoplasm. The nucleus plays a key role in the development of the Daughter Cells as it directs various processes. Initially, the Daughter cells are smaller than the parent cell due to diversified division but ultimately catch up and grow in the later stages of its life. The daughter cells do contain the same number of chromosomes but may have different sets of them randomly.

Hi,
I don't undestand how epidemiology, through targeted studies, has made it possible to make public health choices to fight cancer. In particular why there is systematic screening for breast, prostate or colon cancer but not systematic for the pancreas, testicle, bladder, etc.
Thanks in advance !
Answers
Epidemiology is the study of patterns, causes, and effects of health and disease conditions in populations. Through targeted studies, epidemiologists have identified risk factors for various types of cancer, which has led to the development of screening programs and other public health interventions.
Breast, prostate, and colon cancer are among the most common types of cancer and have well-established screening programs in place. This is because these types of cancer have a relatively high incidence rate, and screening tests are effective in detecting early stages of the disease when treatment is most effective. In addition, there are well-established risk factors for these types of cancer, such as age, family history, and lifestyle factors like diet and physical activity.
In contrast, screening for other types of cancer, such as pancreatic, testicular, and bladder cancer, is not as systematic. This is because these types of cancer have a lower incidence rate, and screening tests are less effective in detecting early stages of the disease. For example, pancreatic cancer is often diagnosed at an advanced stage because symptoms do not appear until the disease has progressed. Testicular cancer is relatively rare, and self-examination is often effective in detecting early signs of the disease. Bladder cancer is often diagnosed after symptoms appear, but there is ongoing research into the effectiveness of screening tests for this type of cancer.
In addition to incidence rates and screening effectiveness, other factors that influence public health choices for cancer prevention and control include cost-effectiveness, access to healthcare, and potential harms associated with screening tests. For example, some types of cancer screening tests, such as mammography for breast cancer, can lead to false-positive results and unnecessary follow-up procedures, which can cause anxiety and additional costs.
In summary, epidemiology has played a crucial role in identifying risk factors for various types of cancer, which has led to the development of screening programs and other public health interventions. The choice to implement systematic screening for breast, prostate, and colon cancer is based on a combination of factors, including incidence rates, screening effectiveness, cost-effectiveness, access to healthcare, and potential harms associated with screening tests.

How is it possible that a family with the same genotypes as the Romanov’s have no children with hemophilia
Answers
Hemophilia is a genetic disorder caused by a mutation in the X chromosome. Females have two X chromosomes, while males have one X and one Y chromosome.
How to describe hemophilia ?Females who carry a mutated X chromosome have a 50% chance of passing it on to their offspring. Males who inherit the mutated X chromosome from their mother will have hemophilia, while females who inherit the mutated X chromosome will be carriers of the disorder.
In the case of the Romanov family, it is possible that the female members who carried the mutated X chromosome did not pass it on to their offspring. It is also possible that some of the male members who inherited the mutated X chromosome died before having children, or their children died before being diagnosed with hemophilia. Additionally, it is possible that some of the members of the family were misdiagnosed, or that there were other genetic factors that influenced whether or not someone developed hemophilia.

could not exist - refers to the inability of it being there, it's presence is basically there/ not there
decomposers - is an organism that breaks down organic materials from dead organisms to obtain energy such as fungi, bacteria, worms and so forth.
