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

Biology

kotegsom [21]3 years ago
6 0

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.

In phototropism, give examples of a positive and a negative response in a plant.
Ghella [55]

Answer:

Phototropism refers to the movement of of plant body or parts towards or away from the light. There are two types of phototropism i. e. positive phototropism and negative phototropism.

In positive phototropism, the parts of plant body moves toward light. Movements of radical in the upward direction after seed emergence is the example of positive phototropism.

In negative phototropism, the body part of plant moves away from the light. Roots are the example of negative phototropism.

Which statements describe scientific inquiry? Check all that apply.
ohaa [14]

Available options are:

A. a scientific inquiry is used only by scientists.

B. scientific inquiry is a process of asking and answering questions.

C. scientific inquiry has only one correct pathway.

D. scientific inquiry often involves similar processes and practices.

E. scientific inquiry involves performing investigations and collecting data.

Answer:

B, D, E

Explanation:

Given that scientific inquiry is a term that described how people mostly scientists, observe the natural world and then come out with credible justification established on the findings that were derived.

Hence, the statements that describe scientific inquiry are:

1. B. scientific inquiry is a process of asking and answering questions. Through this, scientist want to understand the reason behind a certain phenomenon

2. D. scientific inquiry often involves similar processes and practices. To carry out scientific studies, certain steps and practices are required, regardless of the subject under study, which does not entirely change.

3. E. scientific inquiry involves performing investigations and collecting data. This is because to carry out a scientific inquiry, part of the steps and practice includes performing investigations and collecting data, regardless of the subject under study.

Muscle fibers are directly surrounded by which thin layer of connective tissue?
wlad13 [49]

Answer:

The correct answer will be- epimysium

Explanation:

Epimysium is the fibrous connective tissue envelope which surrounds the muscle fibers of the muscle as a whole.

The epimysium plays an important role in maintaining the muscle structure as it protects the muscle from the friction caused by the associated bones and the muscles. The epimysium is continuous with other layers called the endomysium, perimysium, tendons and the fascia.

Thus, epimysium is the correct answers.
