How is it that the same tertiary structure of a protein can result from different primary structures? Select one: a. Any protein
slamgirl [31]

Answer:

I believe that the best answer to the question: How is it that the same tertiary structure of a protein can result from different primary structures? Would be, B: None of the above.

Explanation:

This is probably the best choice from all the ones in the list simply because due to specific portions of the other answers they make the statement incorrect.

It will help to remember this: proteins have primary, secondary and tertiary structures because when they first emerge from the trascription process from mRNA, they are a simple string where the most important factor is the sequence of aminoacids. It is this sequence which will determine the folding factor. However, there is another factor that must always be kept in mind; environmental factors (temperature, medium where the protein is, as well as location where it is being produced) will also play a role on how the folding will happen and on which of the aminoacids.

The evolvement of a protein chain from its primary, to its secondary and then tertiary shape (the only functional, or known as native state) depends on which of the aminoacids in a specific sequence has the necessary elements to form bonds (hydrogen bonds) with others and thus start the folding process.

Which data would not affect maximum likelihood estimates of phylogenies when comparing different tree hypotheses?.
Leona [35]

The set of species derived from one common ancestor.

To build phylogenetic trees, a variety of data can be employed, including genetic information, mitochondrial DNA sequences, ribosomal RNA genes, and any relevant genes, as well as morphological information such as structural characteristics, organ kinds, and specific skeletal arrangements

<h3>What is a Phylogenetic tree ?</h3>

A phylogenetic tree, also called a phylogeny, is a diagram that shows the evolutionary branches from which various species, creatures, or genes have descended from one another.

  • A phylogenetic tree can be used to track a species' evolutionary history back via the tree's branches and find their common ancestors along the way.

  • A lineage may preserve some of its ancestors' characteristics over time, but it will also change over time to accommodate the environment.

Forensic investigators find a widespread dispersal pattern of elongated bloodstains on a wall with a void at the point of origin
gulaghasi [49]
<span>Forensic investigators observe the crime scene and gather any physical evidence that is found and document the analysis done on them. Sketches and the photos taken at the crime scene are also the part of the evidence they collect. Since here the bloodstains found by the Forensic investigators are less than 1mm diameter, they can deduce the weapon used for crime would be shotgun as it has a narrow barrel.</span>
