PYTHON Which of the following are valid ways to create a DNASeq object for the DNA sequence, GATCGATCGATC? (Select all that apply.)

		DNA_seq = new Seq("GATCGATCGATC")
		DNA_seq = Seq(IUPACUnambiguousDNA() ,"GATCGATCGATC")
		DNA_seq = Seq("GATCGATCGATC")
		DNA_seq = Seq("GATCGATCGATC", IUPACUnambiguousDNA())

Expert Solution

Given-

The question comprises of finding the valid ways to create a DNASeq object for the DNA Sequence.

Answer-

DNA_seq = Seq("GATCGATCGATC")

option 3

DNA_seq = Seq("GATCGATCGATC", IUPACUnambiguousDNA())

option 4

Explanation-

These seq objects relationg to the DNA Structures like nucleotides, mutables etc comes under "Biopython", which are generally derived from the library: " Bio.Seq " in which there is a subpackage "Seq".

In order to create a new Seq object, the general syntax is:

new = Seq("Required DNA Sequence object to be created","optional biological alphabet")

here: new is the object name, which can be of any specific choice and is left to the user to implement it:

Therefore option 3 is correct.

Coming back to the syntax specified above: There is a second optional term in object creation : which is known as the biological alphabet:which are of wide varieties and be used to the specific requirement, in which one of it is IUPACUnambiguousDNA: which generally specifies that the sequence is of uppercase unambiguous DNA.

Therefore option 4 is also correct.

DNA mutations can occur in a variety of ways. Choose one of the ways that DNA mutations can occur that you are learning about this week, identify and briefly describe it. Then, choose a genetic mutation (it can be from your textbook, one you are aware of, or one you learn about through your research of this topic), and describe the type of mutation that it involves. Consider if it affects the ability of the organism to produce proteins correctly,...

Python Program: Description Create an object-oriented program that uses inheritance to perform calculations on a rectangle or a square. Specifications Use a Rectangle class that provides attributes to store the height and width of a rectangle. This class should also provide methods that calculate the perimeter and area of the rectangle. Use a Square class that inherits the Rectangle class. This class should set the height and the width of the Rectangle superclass to the length that’s set in the...
