Knowledge of the amino acid sequences is important for several reasons. What is NOT one of those reasons
kotegsom [21]

Complete question:

Knowledge of the amino acid sequences is important for several reasons. What is NOT one of those reasons

  1. Amino acid sequences determine the three-dimensional structures of proteins.  
  2. Knowledge of the sequence of a protein can help to prevent mutations.
  3. The sequence of a protein reveals much about its evolutionary history.
  4. The sequence of a protein is necessary to determine its function.

Answer:  

Knowledge of the sequence of a protein can help to prevent mutations.

 Explanation:  

<em>Amino acids connect to each other by peptidic bonds </em>to form a <em>linear polymer</em>. The number of amino acids composing the chain and the order in which they are arranged determines the primary structure of the protein.

The secondary structure is the folding that the polypeptide chain adopts thanks to the formation of <em>hydrogen bonds between the atoms that form the peptide bond.</em>

<u>Protein functions depend on their aminoacids sequences</u><u>.</u> <u>The primary structure of the proteins determines the three-dimensional one</u>. Proteins with different functions have different sequences. And among species, proteins with similar functions have similar structures.

By knowing the sequence of amino acids, we can predict the function of the protein and we can classify them into different families. Integrants of these groups have at least 25% of their sequences identical to each other.  

Also, the knowledge of the sequence allows establishing evolutionary and genetic relationships between different species.

When a mutation occurs in the sequence -an alteration in the primary structure- the protein function is modified. BUT knowing the sequence of a protein CAN NOT help to prevent mutations.

Sickling occurs in deoxyhemoglobin S but not in oxyhemoglobin S. Oxyhemoglobin has a small, hydrophobic pocket in a β chain regi
Naddik [55]

Answer:

A & B

Explanation:

Leucine and phenylalanine have hydrophobic side chains, which means that they can interact with valine in the pocket. All other aminoacids on the list have polar (two electrically charged) side chains and cannot form hydrophobic pockets.

<h3></h3>

Agroscience is a branch of science that has been increasing circumstantially. Plant breeding is essential for the future of humanity, with this statement we run through the questions.

<h3 /><h3>1. How might hyperscience contribute to the controversy surrounding the  genetic modification of plants? At the same time, how might hyperscience  contribute to a healthier environment?</h3>

Plant breeding is the science and art of genetically modifying plants to make them more useful to humans, thus developing new varieties that are more resistant to pests and diseases, more productive, with better nutritional quality, more adapted to different soils, climates and regions, and with other different characteristics of interest for the benefit of the population.

<h3>2. Agriscientists are developing genetically modified plants to address a  number of problems and, at the same time, working to sustain heirloom  varieties of those same plants. Why do you think both activities are  important to plant science?</h3><h3 />

The genetic modification of organisms, which generates transgenics, is part of plant breeding. It is biotechnology, genetic engineering applied to plant breeding. It is modern plant breeding, carried out in the laboratory, to introduce characteristics of other species into the variety that we want. We can, through genetic modification of plants, bring genes from beans and put them in soy, from rice into soy, from soy into wheat, from bacteria into soy, and so on.

<h3 /><h3>3. How might both farmers and amateur gardeners with small home plots of  land benefit from developments made by agriscientists?</h3><h3 />

Plant breeding is the best strategy for food security because, through the development of pest and disease resistant varieties, we can ensure greater production stability. By developing varieties that are more tolerant of adverse weather conditions, we can stabilize production. Therefore, plant breeding is a highly responsible strategy from an environmental point of view, because through it, production can be increased without the need to incorporate new productive areas into the production system. In this way, plant breeding becomes a great help in food security and in the preservation of the environment.

<h3>4. Imagine you are an agriscientist trying to improve urban gardening. What  two technologies or advancements do you believe would appeal most to  urban gardeners and why?</h3>

The improvement of two characteristics are of great importance for an urban vegetable garden, the first would be resistance to high temperatures, as in cities the tendency is for temperatures to be higher than in the field and time for fruiting and harvesting, as cities have a faster dynamics for things.

<h3>5. Describe two ways that agriscience appeals to people with very different  skill sets. Why do you think this career path offers so much opportunity in  so many different areas?</h3>

Humanity will increasingly need advances in agroscience because natural resources are becoming scarce and adaptation and large production in agriculture is linked to this factor.

Every day when we eat fruits or vegetables, there has been an advance in agriculture so that it is possible, the advance of agroscience is indispensable for the present day.
