Q4. Consider the following DNA fragment:
...GTACCCGACACTTCCGTCCCCTTC... Assume that the
frequencies of symbols in the rest of the sequence are the
same as in this ?agment. Estimate the probabilities of each
symbol {A, G, T, C} and hence derive the Huffman code
for each. Estimate the average number of bits per symbol
required to encode the sequence using Huffman code un-
der these circumstances.
Q5. Write Short Note on:
(a) Arithmetic encoding
(b) Run length encoding
(c) 1.2 and LZW
