which of the following is not a way nucleosome formation affects dna? group of answer choices the dna is compacted. the access to dna by enzymes is altered. binding of h1 destabilizes the nucleosome, alleviating the transcriptional repression exerted by the binding of nucleosome histones. transcription is inhibited by the tight, internucleosome connections mediated by histone tails. binding of the transcription factor sp-1 can alleviate the transcriptional repression exerted by the histone binding.

Answers

Answer 1

The answer to this question is option 4 - transcription is inhibited by the tight, internucleosome connections mediated by histone tails. Nucleosomes are structures formed by DNA and histone proteins.

These structures play a vital role in regulating the accessibility of DNA to transcription factors and other enzymes that are necessary for gene expression. The compacting of DNA in nucleosomes can make it challenging for enzymes to access the DNA, altering the expression of genes. The binding of H1 destabilizes the nucleosome, which alleviates the transcriptional repression exerted by the binding of nucleosome histones. This destabilization can allow transcription factors and enzymes to access DNA, enabling gene expression. Similarly, binding of the transcription factor SP-1 can alleviate the transcriptional repression exerted by the histone binding. This binding can also enable gene expression.
However, the tight, internucleosome connections mediated by histone tails can inhibit transcription. These connections make it difficult for transcription factors and enzymes to access DNA, thus blocking gene expression. Therefore, the tight connections between nucleosomes are not a way nucleosome formation affects DNA positively.
In summary, nucleosome formation affects DNA in various ways, and it can either facilitate or inhibit gene expression. The compacting of DNA in nucleosomes can make it challenging for enzymes to access the DNA, altering the expression of genes. The binding of H1 and SP-1 can alleviate the transcriptional repression exerted by the histone binding, while tight internucleosome connections mediated by histone tails can inhibit transcription.

Answers

Multicellular parasites are primarily cleared by the activity of phagocytic cells.

Here, correct option is A.

However, they also provoke strong immune responses due to the high antigenicity of parasite antigens. In terms of specific immune responses, different types of parasites may be effectively cleared by different types of immunity.

Multicellular parasites are most effectively cleared by type 2 immunity. This immune response is characterized by the activation of specific immune cells, such as eosinophils, mast cells, and basophils, which help to combat these larger parasites.

For example, some multicellular parasites may be most effectively cleared by type 2 immunity, while others may be primarily cleared by type 1 immunity. Additionally, some parasites may be cleared by responses occurring in mucosal tissues that are dependent upon IgA secretion.

which of the following is true about glucagon's action? group of answer choices glucagon is a signal (that indicates starvation) to stimulate glycogen degradation. glucagon acts mainly on muscle cells to stimulate glycogen breakdown in those cells. glucagon acts directly on a membrane protein called adenylate cyclase which then produces cyclic amp. glucagon is synthesized in the liver. glucagon triggers synthesis of glucose in the liver.

Answers

It is true that glucagon acts as a signal (that denotes famine) to promote glycogen breakdown. Option 1 is Correct.

A crucial factor in controlling the metabolism of glucose is the hormone glucagon, which is generated by the alpha cells of the pancreas. As blood glucose levels drop, the hormone glucagon is released into the bloodstream to tell the liver to release glucose into the bloodstream to keep blood glucose levels stable.

Moreover, glucagon encourages gluconeogenesis, or the production of glucose from non-carbohydrate sources including fatty acids and amino acids. Glucagon stimulates glycogen breakdown and glucose production by acting on liver cells rather than muscle cells. It works by activating an adenylate cyclase-coupled G protein-coupled receptor on the cell membrane, which causes the synthesis. Option 1 is Correct.

An antigen produced by a pathogen while living inside a cell is known as an endogenous antigen.

Endogenous antigens are antigens that are produced by cells within the body, such as virus-infected cells or cancer cells. These antigens are processed and presented on the surface of the cell in the context of major histocompatibility complex (MHC) molecules. This allows the immune system to recognize and mount a response against the infected or abnormal cells.

In contrast, exogenous antigens are antigens that are derived from outside the body, such as from a pathogen that has entered the body through the skin, digestive tract, or respiratory tract. These antigens are taken up by antigen-presenting cells, such as dendritic cells, which process and present them on the surface of the cell in the context of MHC molecules.

Autoantigens are self-antigens that are produced by the body's own cells and tissues. In some cases, the immune system may mistakenly recognize autoantigens as foreign and mount an immune response against them, leading to autoimmune diseases.

spinal nerves are spinal nerves are purely motor. both sensory and motor. involuntary. interneuronal. purely sensory.

Answers

Spinal nerves are not purely motor or purely sensory, but rather they are mixed nerves that contain both sensory and motor fibers. The sensory fibers in spinal nerves carry information from the body to the central nervous system (CNS), while the motor fibers carry commands from the CNS to the muscles and glands in the body.

Spinal nerves are not purely motor, but rather contain both sensory and motor fibers. These nerves originate from the spinal cord and extend out to various parts of the body. They are essential for transmitting signals between the central nervous system and the rest of the body.

Each spinal nerve contains both sensory and motor fibers, which are bundled together within a protective sheath called the epineurium. The sensory fibers are responsible for transmitting sensory information, such as touch, temperature, and pain, from the body to the spinal cord and brain. The motor fibers, on the other hand, are responsible for transmitting motor commands from the brain and spinal cord to the muscles and other organs.

It's important to note that spinal nerves are not involuntary. In fact, many of the movements that we make every day, such as walking, running, and lifting objects, are under voluntary control and are mediated by spinal nerves.
