1 Represent all possible base.
. There are four possible bases. Cytosine guanine adenine and thymine abbreviated as C G A and T. With unlimited bases there are 4 8 or 65536 possible sequences.
Several specific types of DNA sequence variants are frequently observed Fig. The most frequent form of variation the single nucleotide polymorphism SNP refers to the situation in which a single base in the sequence of one individual is different from the base seen at the. There are many possible ways in which DNA sequences can vary.
In one twin gene A may be going full blast while in the other gene A is barely on. How many different DNA sequences of length 4 consist of exactly two different letters. Same DNA different people.
If you have 8 bases available there are 2520 possible sequences. Start studying the DNA Quizlet flashcards containing study terms like What is DNA What is the shape of DNA Who are the two scientists who are accredited on saying that DNA is a. A DNA strand consists of eight pairs of nitrogenous bases.
For comparing 2 sequences youll need to perform a pairwise alignment. So that means there are 4. The number is essentially infinite.
Assuming each base is in equal amounts the answer is 65536There are four bases possible for each spot. A base may appear more than once in a codon. Ask Question Asked 7 years 6 months ago.
The goal is for sequencing to cost less and be done faster. Thus a chain of 5100 nucleotides. A sequence of three bases is called a codon.
If we have to make 8 pairs of bases the number of possible sequences would be 4 to the power 8. So there will be many different sequences. DNA bases are read one at a time as they squeeze through the nanopore.
B Answer the question in part a using counting rules. How many different sequences of eight bases of DNA can you make. Modified 7 years.
MUSCLE or one of the Clustal algorithms like ClustalW. 2 4 are all wrong. The information in RNA although copied into another chemical form is still written in essentially the same language as it is in DNAthe.
Each human has two versions of his or her genome one from each parent. There are four nitrogenous bases that occur in DNA molecules. Use a tree diagram to determine the number of different shoes that a store has to stock to have at least one pair of this type of running shoe for all available sizes and colors for both men and women.
2 4 2520. So how many different variants of human are there. Since we have 4 nitrogenous bases pairing will make 4 X 4 16 combinations.
How many sequences can I align. THERE WILL BE 65536 DIFFERENT SEQUENCES OF 8 BASES. Therefore the answer is 65 536 possible sequences.
Since DNA is made up of 8 pairs of nitrogenous bases then we have the ability to create almost an infinity of different structures because the combinations are so diverse. RNA molecules contain cytosine guanine and adenine but they have a different nitrogenous base uracil U instead of thymine. Earn 10 reputation not counting the association bonus in order to answer this question.
A and T T and A C and G and G and C. How many different sequences of eight bases can you make. Follow answered Sep 15 2014 at 2311.
The bases are the same they still have an identical DNA sequence. Most programs will align 3 or more sequences at a time and will require a different algorithm eg. In the sequence of 8 it would be 4 possible bases to the power of 8 because you need to multiply 4 eight times for the number of sequences.
So that means there are. 2 4 2520. Each version consists of a sequence of approximately 3 billion DNA bases.
Explain how you found your answer Their answer. Portions of DNA Sequence Are Transcribed into RNA. How many different sequences of eight bases of DNA can you make.
A How many different 8-mer sequences of DNA are there. DNA molecules consist of chemically linked sequences of the bases adenine guanine cytosine and thymine denoted A G C and T. The first step a cell takes in reading out a needed part of its genetic instructions is to copy a particular portion of its DNA nucleotide sequencea geneinto an RNA nucleotide sequence.
DNA sequence information is important to scientists investigating the functions of genes. Using an estimate of mutation frequency of around 2 x 10-8 per base pair per replication event we get 60 novel mutations in every living human being.

Two antiparallel polynucleotide chains coiled in a helix around a common axis that the pyrimidine and purine bases lie on the inside of the helix. Memorize flashcards and build a practice test to quiz yourself before your exam. Therefore the answer is 65 536 possible sequences.
In fact your approach counts each sequence 2 4 times since you can either switch or not-switch each of the four types of base pair so another way to get the same answer is 8. The bases are identified by measuring differences in their effect on ions and electrical current flowing through the poreUsing nanopores to sequence DNA offers many potential advantages over current methods. DNA sequencing is a laboratory technique used to determine the exact sequence of bases A C G and T in a DNA molecule.
The features of DNA deduced by Watson and Crick included. There are 16 possible dinucleotides and 64 possible trinucleotides We can quantify the information-carrying capacity of the nucleic acids in the following way. There are four bases possible for each spot.
There are 6cdot1484 possibilities. 4 x 4 16 there would be 16. When comparing two versions of a human genome either within the same person or between two different people about 11000 of these bases vary ie 999 of them are the same Table 32.
For 8 base pairs there are 4 8 65536 possible combinations. The difference is that they are using their genes differently -- their dimmer switches are set to different levels. The DNA base sequence carries the information a cell needs to assemble protein and RNA molecules.
How many different sequence possibilities are there for a DNA polymer that is 10 bases long. You must have a minimum of 2 sequences to perform an alignment. Assuming each base is in equal amounts the answer is 65536.
