Answer #1

To perform bayesian inference, Mrbayes software is used for phylogenic reconstruction. It is based on posterior distribution of trees , which is the probability of tree conditioned on the observation. Probability distribution of tree often impossible to calculate analytically. Therefore , Mr bayes used a simulation technique called Markov chain Monte Carlo to calculate posterior probability of tree. There is more time needed for markov chain analysis to converge thats why not suitable for databases with more than 100 sequence. Thats it limit 30 sequence for reliable result in appropriate time.

Why are DNA sequences (or amino acid sequences encoded in genes ) such powerful characters for use in cladistics?                                      A.)because each nucleotide in the sequence is a separate character, yielding millions of characters.                                                                        B.)DNA is the only rigorous way in which to assess evolutionary relatedness.                                C.)It yields inherently more robust characters.

A) LINES and SINES are longer sequences and they do not repeat in tandem. Why are they called repetitive? (Be sure you understand what they words in tandem mean.) B) Together LINES and SINES make up what percent of the DNA of the human genome? C) Let's conclude with an interesting fun fact... the human genome has about 20,000 functional genes. This DNA sequence only accounts for what percent of the entire human genome?
