Complete question:

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

Amino acid sequences determine the three-dimensional structures of proteins.
Knowledge of the sequence of a protein can help to prevent mutations.
The sequence of a protein reveals much about its evolutionary history.
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:

Amino acids connect to each other by peptidic bonds to form a linear polymer. 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 hydrogen bonds between the atoms that form the peptide bond.

Protein functions depend on their aminoacids sequences. The primary structure of the proteins determines the three-dimensional one. 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.

How does the economy influence energy source choices?

trapecia [35]

Since the resources aren't efficient enough and the supply isn't meeting the demands of the growing populace as economics dictates. Humans paved way into this renewable energy.

The use of our renewable energy resources provides great benefits for our health, climate and the economy. One of the benefits of using these resources are it lessens the destruction pace of the ozone layer that greatly contributes to the global warming. Considering that the negative effects of the global warming will be decreased it naturally means that there is an improved health of the people in the community because of the usage of organic ang renewable energy. It also strengthens and improves the economy of the country because the country no longer needs to import resources if there is renewable energy.

Solar Energy since the sun's sunlight is almost avaible anywhere in the globe and the solar panels are getting more localised for more countries which can be easier for everyone to have.

The sun is the unlimite sorcuse of engery true or false

vlada-n [284]

<h2>Answer:</h2>

True. Yes the sun is the ultimate source of energy.

Explanation:

We all living organism needs energy for their survival like for walking, talking and breathing.
Energy is required by every cell for their reproduction, growth and maintenance.
We all eat food to get that energy. Food is consists of plants and meat of some animal.
These some animals also get food from plant.
Plants take sun light to make their food/energy.
Sun just provide energy in form of food. It dose not get energy from anywhere.
Hence we all are ultimately depends on sun.

So that they don't explode.

AKA with a thing called osmosis (transportation of water through cells.)

The role of rRNA in gene expression is to?

Verizon [17]

Answer:

The correct answer is rRNA plays an important role during translation (protein synthesis) of mRNA.

Explanation:

Ribosomal RNA or rRNA are the RNA molecules which build up the site for protein synthesis known as ribosomes.

Ribosome synthesis takes place in nucleolus where two types of rRNA molecules associates with proteins, one in large subunit and one in the small subunit to form ribosomes.

These ribosomes physically moves along an mRNA molecule and catalyze the assembly of amino acids where rRNA molecules performs the catalytic steps of protein synthesis that is stitches amino acids together and makes up proteins.

Thus, rRNA plays an important role during translation (protein synthesis) of mRNA.
