How can the expression of a single gene be quickly, efficiently, and specifically shut down at the transcriptional, posttranscriptional, and posttranslational stages through coordinated expression of a transcriptional repressor, an miRNA, and a ubiquitin ligase?

Answers

Answer 1

Answer:

Ubiquitin ligase is a protein enzyme recruits Ubiquitin-conjugating enzyme that come with the ubiquitin and catalyzes the transfer of ubiquitin to the protein substrate of interest and destructed by the proteosome.

miRNA are small RNA molecules with no coding behavior that binds with the mRNA with the help of base pairing of complementary codes. It helps in mRNA degradation and cutting of poly-A tail of mRNA type of gene expressing.

A gene-specific transcriptional repressor helps in preventing the transcription process of the mRNA by inhibiting the binding of the RNA polymerase to the promoter.

Ecosystem

Explanation:

An ecosystem refers to all the abiotic and biotic factors in an area and their interactions.

The biotic factors include all the living organisms (the fish, their predators, and the plants).

The abiotic factors are the physical, non-living components, including the water and sunlight.

The relationships between all these factors creates the ecosystem.

Describe how positive control in prokaryotes can be altered by the external environment

Answers

Answer:

The positive control is control when there is an activator present which acts as a regulatory protein so the operon and activator binds and initiates the stimulation of transcription to express the gene. In absence of this activator or regulatory protein, the operon will be inactivated.

External environmental stimuli can lead to alteration of the positive control in prokaryotes such as excess lactose in the environment. These environmental stimuli can induce transcription in prokaryotes.

In this example, if glucose is not available in the environment, the transcription of the lac operon will be induced by the presence of lactose in the environment.

Answers

Answer:

Explanation:

Proteins are long-chain macromolecules made up of amino acid monomers.  Amino acids are organic compounds with an amine and carbonyl group. They contain Carbon, Hydrogen, and Oxygen, along with Nitrogen as their basic elements.  They are often found in meat, fish, dairy and legumes.

In the body, proteins are important immunomodulation and the immune response. The body produces antibodies (Ab) or immunoglobulin (Ig) to help neutralize or tag foreign invaders by binding to specific antigens on the pathogen's surface.

Answers

Answer:

nucleotides

Explanation:

DNAs are long-chain, helical macromolecules that store genetic information They are made up of varying sequences of covalently bonded monomers called nucleotides. Four types of nucleotides make up the nucleic acid DNA, these include Adenine, Guanine, Cytosine and Thymine.

Unlike other macromolecules,  these are typically not used as an energy source and only encode protein synthesis. They comprise a 5-Carbon deoxyribose sugar, one nitrogenous base (adenine, guanine thymine, and cytosine) and a phosphate group.

Nitrogenous bases encourage base-pair formation through hydrogen bonding. Adenine forms double bonds with thymine, while cytosine forms triple bonds with guanine.

Explain why the ratio of motor neurons to muscle fibers is greater in muscles that control eye movement than in postural muscles of the leg.

Answers

Answer:

The muscles of the eye cover a greater number and in turn carry out greater fine motor skills.

Explanation:

Alpha motor neurons are neurons that invent the skeletal muscle, that is, striated, so that through the motor plate that is the unit that unites them, an action potential is transmitted that contracts the sarcomeros of the elastic fibers and the z lines. come closer, each eye movement is much more precise than the locomotion of the lower limb, which carries greater innervation in each muscle bundle due to the specificity of the movement, this is how more alpha motor neurons are required to mobilize the eye than a leg.

The specificity and preciseness of eye movement control justifies why the ratio of motor neurons to muscle fibers is greater for muscles controlling eye movement than those in the postural muscles of our leg.

The function the eyes performs requires more precise locomotion control than the movement of the limbs require.

For an eye movement to be made, an action potential must be transmitted which makes the sarcomeres of the elastic fibers and z-lines to unit thereby producing movement of the eye. This movement are usually done with almost perfect preciseness.

This is why there are more alpha motor neurons that control eye movement than we have in postural muscles of the leg.

In summary, the specificity and preciseness of eye movement control justifies why the ratio of motor neurons to muscle fibers is greater for muscles controlling eye movement than those in the postural muscles of our leg.

Do all living things obtain the matter and energy they need to live and grow in the same way?​

Answers

Answer:

Explanation:

This means all living organisms must obtain and use energy to live. Energy is the power to do things. ... A living organism can either make its food or depend on others to make food for them. For example, green plants produce their food from a process called photosynthesis.

Living things obtain energy and food to grow but different organisms do in different ways plants depend on the sun for photosynthesis.

How do living things obtain energy?

Every living thing has a unique method of getting nutrients. Protozoans and other animals are among the creatures that obtain nutrition by eating food. Through the process of photosynthesis, plants and algae produce their own sustenance.

Animals consume food and drink to get the substance and energy they require for their biological activities.

A producer is an organism that produces its own nourishment. Sugars, a source of both energy and substance, are produced by plants using the energy from sunshine.

Therefore Plants are one type of creature that can produce its own food, to obtain energy.
