1) Why does the addition of dideoxynucleotides to the DNA sequencing reaction cause DNA synthesis to stop after the modified nucleotide is added?
A)Because once a modified nucleotide is incorporated into the DNA, there is no free 5'OH group to attach the next nucleotide being added.
B)Because once a modified nucleotide is incorporated into the DNA, there is no free 3'PO4-group to attach the next nucleotide being added.
C)Because once a modified nucleotide is incorporated into the DNA, there is no free 3'OH group to attach the next nucleotide being added.
D)Because once a modified nucleotide is incorporated into the DNA, there is no free 5'PO4-group to attach the next nucleotide being added.

Answers

In Sanger sequencing, once a modified nucleotide is incorporated into the DNA, there is no free 3'OH group to attach the next nucleotide being added. This phenomenon is useful to sequence a polynucleotide chain.

Dideoxynucleotides (ddNTPs) are nucleotide inhibitors of the DNA polymerase, it is for that reason that they are used in Sanger sequencing.

The ddNTPs are similar to natural deoxynucleotides used by cells during ADN replication; however, ddNTPs lack a hydroxyl (OH) group on the 3’ carbon of the deoxyribose.

In consequence, once a ddNTP is added, DNA synthesis cannot progress, thereby this phenomenon can be used to determine the order of nucleotides during the elongation of a polynucleotide DNA chain.

Courtship can be defined as the behavior used to obtain copulation with a partner, or to maintain reproductive interactions with an existing partner.Courtship, in animals, behaviour that results in mating and eventual reproduction. Courtship may be rather simple, involving a small number of chemical, visual, or auditory stimuli; or it may be a highly complex series of acts by two or more individuals, using several modes of communication.It help strengthen a pair bond that may last through the raising of the young or even longer.Courtship is its use as an isolating mechanism, a method of keeping different species from interbreeding.

Which term can avoid traveling through a solid, a liquid, or a gas?

Answers

The term that can avoid traveling through a solid, a liquid, or a gas is "electromagnetic radiation" or "light."

Electromagnetic radiation: Electromagnetic radiation refers to the propagation of energy in the form of waves or particles through space. It includes various types of radiation, such as visible light, radio waves, microwaves, X-rays, and gamma rays.Traveling through solids: Solids have a tightly packed arrangement of atoms or molecules, which makes it difficult for electromagnetic radiation to pass through them. The particles in solids interact with the radiation and absorb or scatter it, preventing its transmission.Traveling through liquids: Liquids have a less rigid arrangement of particles compared to solids. While some electromagnetic radiation can pass through liquids, it may be partially absorbed or scattered due to interactions with the liquid molecules.Traveling through gases: Gases have widely spaced particles, allowing electromagnetic radiation to travel more freely compared to solids and liquids. However, certain gases can still interact with specific types of radiation, such as absorbing certain wavelengths or causing scattering.

Overall, electromagnetic radiation, or light, has the unique property of being able to propagate through a vacuum, which means it can travel through space where there is no matter present, as well as through various mediums, including gases, liquids, and solids.

In what ways can the use of statistics help in improving mental health services? Could the use of statistics cause potential misunderstandings of mental health services? How can you avoid any such misunderstandings?

Myths, misunderstandings, and negative stereotypes and attitudes surround mental illness. These result in stigma, discrimination,and isolation of people with mental illness, as well as their families and carers.

----------------------------------------------------------------------------------------------------------------

Are mental illnesses a form of intellectual disability or brain damage?

No. They are illnesses just like any other, such as heart disease, diabetes, and asthma. Yet the traditions of sympathy, support, and flowers given to people with physical illnesses are often denied to those with a mental illness.

Are mental illnesses incurable and lifelong?

No. When treated appropriately and early, many people recover fully and have no further episodes of illness.

For others, mental illness may recur throughout their lives and require ongoing treatment. This is the same as many physical illnesses, such as diabetes and heart disease. Like these other long-term health conditions, mental illness can be managed so that individuals live life to the fullest.

Although some people become disabled as a result of ongoing mental illness, many who experience even very major episodes of illness live full and productive lives.

Are people born with a mental illness?

No. A vulnerability to some mental illnesses, such as bipolar mood disorder,can run in families. But other people develop mental illness with no family history.

Many factors contribute to the onset of a mental illness. These include stress, bereavement, relationship breakdown, physical and sexual abuse, unemployment,social isolation, and major physical illness or disability. Our understanding of the causes of mental illness is growing.

Can anyone develop a mental illness?

Yes. In fact, as many as one in five Australians may develop a mental illness at some stage in their lives. Everyone is vulnerable to mental health problems.

Many people feel more comfortable with the notion of having 'a nervous breakdown' rather than a mental illness. However, it is important to talk openly about mental illness, as this reduces the stigma and helps people to seek early treatment.

Are people with mental illness usually dangerous?

No. This false perception underlies some of the most damaging stereotypes. People with a mental illness are seldom dangerous. Even people with the most severe mental illness are rarely dangerous when receiving appropriate treatment and support.

Should people with a mental illness be isolated from the community?

No. Most people with a mental illness recover quickly and do not even need hospital care. Others have short admissions to hospital for treatment. Improvements in treatment over recent decades mean that most people live in their communities, and there is no need for the confinement and isolation that was commonly used in the past.

A very small number of people with mental illness need hospital care,sometimes against their will. Improvements in treatment are making this less and less common, and fewer than one in a 1000 people are treated this way.

what do you think will happen when i put a leaf discs saturated with a sodium bicarbonate solution and put it under a lamp ? will it sink or float and why ? can someone help me rq will give 30 points

Answers

Answer:

the leaf disk should float because bicarbonate is the source of its oxygen for photosynthesis and it releases oxygen into the interior of the disk causing it to float.

Explanation:

The thing which would happen if leaf discs are saturated with a sodium bicarbonate solution and put under a lamp is:

The leaf disk would float

According to the given question, we can see that there is an experiment which is taking place as a leaf disc is placed in a solution of sodium bicarbonate under a lamp.

As a result of this, we can see that the source of oxygen for the leaf disk is the bicarbonate and when the chlorophyll in the plant reaches out to the lamp for photosynthesis, it would make the leaf disk to float.
