Individual codons code for specific amino acids. A gene is a sequence of nucleotides along a DNA strand-with 'start' and 'stop' codons and other regulatory elements-that specifies a sequence of amino acids that are linked together to form a protein. So, for example, the codon AGC codes for the amino acid serine, and the codon ACC codes for the amino acid threonine. There are a two points to note about the genetic code: 1  It is universal. 2  All life on Earth uses the same code (with a few minor exceptions).
â¦but $3.99 sells the most copies. Smashwordsâ findings suggest that those $2.99 authors should price up by a dollar: âOne surprising finding is that, on average, $3.99 books sold more units than $2.99 books, and more units than any other price except FREE. I didnât expect this. Although the general pattern holds that lower priced books tend to sell more units than higher priced books, $3.99 was the rule-breaker. According to our Yield Graph, $3.99 earned authors total income that was 55% above the average compared to all price points.â.
The typical royalty an author receives, according to the Wall Street Journal, is 15 percent of the retail price for a hardcover, and 25 percent for an e-book. But the prices for e-books are less than half the retail price for a hardcover, reducing the cash payment to the author.he typical royalty an author receives, according to the Wall Street Journal, is 15 percent of the retail price for a hardcover, and 25 percent for an e-book.
