Interesting that the part you didn't do was in a previous comment.

Do you want to calculate or measure the CSI of an organism or teach me to do so and us compare the results?

You seem so ignorant in this subject (don't mean that as a slur just an observation as we are all ignorant in some subjects).

Why on earth would you want to calculate the CSI of an organism? Just a simple genome is lightyears over the 500 measly bits of information that make something CSI. Many proteins are as well...common sense should tell you that.

Look at the amount of information in the human genome:

The human genome contains the complete genetic information of the organism as DNA sequences stored in 23 chromosomes (22 autosomal chromosomes and one X or Y sex chromosome), structures that are organized from DNA and protein. A DNA molecule consists of two strands that form the iconic double-helix “twisted ladder”, whose backbone, which made of sugar and phosphate molecules, is connected by rungs of nitrogen-containing bases. DNA is composed of 4 different bases: Adenine (A), Thymine (T), Cytosine ©, and Guanine (G).  These bases are always paired in such a way that Adenine connects to Thymine, and Cytosine connects to Guanine.  These pairings produce 4 different base pair possibilities: A-T, T-A, G-C, and C-G. The haploid human genome (containing only 1 copy of each chromosome) consists of roughly 3 billion of these base pairs grouped into 23 chromosomes. A human being inherits two sets of genomes (one from each parent), and thus two sets of chromosomes, for a total of 46 chromosomes, representing the diploid genome, which contains about 6×10^9 base pairs.

Comparing the genome to computer data storage
In order to represent a DNA sequence on a computer, we need to be able to represent all 4 base pair possibilities in a binary format (0 and 1). These 0 and 1 bits are usually grouped together to form a larger unit, with the smallest being a “byte” that represents 8 bits. We can denote each base pair using a minimum of 2 bits, which yields 4 different bit combinations (00, 01, 10, and 11).  Each 2-bit combination would represent one DNA base pair.  A single byte (or 8 bits) can represent 4 DNA base pairs.  In order to represent the entire diploid human genome in terms of bytes, we can perform the following calculations:

6×10^9 base pairs/diploid genome x 1 byte/4 base pairs = 1.5×10^9 bytes or 1.5 Gigabytes, about 2 CDs worth of space!

is 1.5 Gigabytes more than 500 bits? Then why would we want to go any further than this as you already have the answer before you start.

ANY organism will be over 500 bits.
