Answer:

Restriction enzymes are DNA-cutting enzymes. Each enzyme recognizes one or a few target sequences and cuts DNA at or near those sequences.

Explanation:

Many restriction enzymes make staggered cuts, producing ends with single-stranded DNA overhangs. However, some produce blunt ends. DNA ligase is a DNA-joining enzyme. If two pieces of DNA have matching ends, ligase can link them to form a single, unbroken molecule of DNA. In DNA cloning, restriction enzymes and DNA ligase are used to insert genes and other pieces of DNA into plasmids.

The diagram below shows some relationships between ecosystems near the

3241004551 [841]

Based on the ecosystems located near the Sonoran and Chihuahuan Deserts, an ecosystem which the thornscrub belongs to is: B. shrubland.

<h3>What is thornscrub?</h3>

Thornscrub can be defined as a transitional biome that exist between a tropical and desert forest. This ultimately implies that, thornscrub comprises grasses, geophytes, and herbs,

In this context, we can infer and logically deduce that an ecosystem which the thornscrub belongs to is shrubland because it's typically made up of a plant community.

100 POINTS!!!!

Answer:

A) A medicine that is personalized towards an individual's DNA.

B) These new technologies will be a benefit towards human health because they will be more effective and will not be as hazardous.

2) The sequencing of the human genome changed the way doctors are analyzing personal disease and risk because they are now able to diagnose the disease risk factors, provide better treatment for patients, determine which type of disease it is more accurately, how much of a dose of medicine the patient needs, and figure out genetic disorders.

3) He is worried that people might be moving too fast regarding these developments and wants them to proceed slowly and carefully so there is no room for error.

4) Some benefits would be protection from other certain diseases, I can fix any sort of genetic disorder, and order it so I can become stronger. However, I’m concerned that there will be risks in the sequencing process, which will change my genome for the worse.

5) Many potential biomarkers have yet to be verified and qualified for use, the FDA has yet to set a regulatory approval pathway for these products, the success of personalized medicine is contingent the ability of scientists and healthcare providers to capture, manage, store, and provide access to data and medical information, in order for personalized medicine to succeed, healthcare providers, patients, and insurers must learn how it works, and there are many privacy, confidentiality and fair-use concerns.

6 It could influence the use of these technologies because rather than focusing on helping people, they will only think about the money, leading them to do it carelessly and recklessly.

A) I think that using the information in a person's genome to treat disease is a good idea because it is much more effective in preventing disease and can fix any sort of genetic disorder much more easily.

B) I think this should be controlled. To address the potential for loss of genetic privacy, make it so that person gives their consent and you only take what is needed without having to look at the whole genome.

Hope this helps

klemol [59]

The largest ecosystem on the planet is the ocean system. The correct option in regards to the given question is option "C". It is a known fact that our earth is covered with 70% water and 30% land. On top of that the marine environment covers about 97%. This is the largest ecosystem on our planet. <span>It is a known fact that our earth is covered with 70% water and 30% land. On top of that the marine environment covers about 97%. This is the largest ecosystem on our planet. The marine world supports a huge amount of life form and there is also the opinion that the first life could have evolved from this system. </span>

spayn [35]

Answer:

D) cofactor necessary for enzyme activity.

Explanation:

Carboxypeptidase is an enzyme found in the digestive system whose function is to hydrolyze a peptide bond in the terminal carbon of a protein. Said enzyme contains a zinc atom in its active site and when losing a zinc atom it would lead to loss of the activity of the enzyme, making it of great importance for the activity of the enzyme.
