Tricky Question: For a phylogeny if you compare two sequences from two different species of zebras:
Zebra 1: A C T T G C A T C
Zebra 2: A C T C G C A T C
the assumption is that the traits at each location in a sequence, represented by the nucleotide letter (A, T, C, G), is...

to the matched DNA nucleotide in the other sequence or other sequences. In other words, that DNA base has a common evolutionary origin.
Homework Answers
Two DNA sequences of zebra are different from each other at one single nucleotide due to SNP.
Hence the answer is Polymorphic /single nucleotide polymorphism (SNP).
SNP represents the variation of the DNA sequence of the allele with a single nucleotide. It is normally present in the populations at the specific location of the genome.

We consider two DNA sequences with the letters A; G; T; and C. Suppose that the letters on different locations are independent with probability P[A] = P[G] = P[C] = 2 and P[T) = }. The sequences both have infinite length (here we idealized of course..) and the two sequences are independent. When the letters are read by a sequence processor an error is made with probability 10-4. Whenever an error is made, the 'wrong' letters are read with equal...

The deoxyribonucleic acid (DNA) is a molecule that contains the genetic instructions required for the development and functioning of all known living organisms. The basic double-helix structure of the DNA was co-discovered by Prof. Francis Crick, a long-time faculty member at UCSD 0 The DNA molecule consists of a long sequence of four nucleotide bases: adenine (A), cytosine (C), gua- nine (G) and thymine (T). Since this molecule contains all the genetic information of a living organism, geneticists are interested...

Requirements: For this exercise you are to implement a small bioinformatics library for operations with DNA sequences, which, in this exercise, are represented as strings of only the characters A, C, G, and T. Three methods are required for this exercise and they are each detailed below. Kmers The term k-mer refers to all the possible substrings of length k that are contained in a DNA sequence. For example, given the DNA sequence AGATCGAGTG the 3-mers are: AGA GAT ATC...

A part of the aminoacid sequence in Cytochrome-C protein from 6 different species is given in the table. Rank the organisms from 1 to 5 according to the similarity of the organism to human: based on the similarity between the cytochrome C aminoacid sequences, 1 being the closest to human. It is largely agreed that the greater the number of amino acid (or nucleotide) differences between a given pair of organisms, the further apart they are in evolution. On the...

Humans and Chimps share a 9,826 nucleotides out of 10,000 in

of 10,000 is 174. Gorillas and my new species differ by only 165
nucleotides. A) K=(-3/4)In(1-(4(0.0174)/3))=0.0176050171.

Sequences of numbers are a useful mathematical tool for exploring transitions and trends. Sequences of symbols create words, and sequences of words create languages, both Human and Computer. While sequences of nucleotides create DNA, which in turn create new sequences of nucleotides called RNA, which in turn creates sequences of amino acids called proteins, which in turn create, among other things, humans that create, among other things, computers. The quest to identify this “Source Code of Life” quickly became the...
