Everything between and including these two codons makes up one gene. There are a couple other stop codons but for now, we're only going to think about TAA. Accordingly, it's called the start codon and the TAA codon is also special in that it indicates the end of a gene, so it's called the stop codon. The ATG codon shown here is special in that it indicates the start of a gene. Three nucleotides together make a codon which each describe one amino acid. Each of these represents one nucleotide which are the basic building blocks of DNA. You will see that it's made up of four letters A T C and G. Here is a string that could represent some piece of DNA. Before we dive into DNA related problems, we need to give you a bit of domain knowledge, some terms and concepts related to working with DNA. Perhaps most importantly, you will get more practice developing and implementing algorithms with the seven steps. Of course, math is also ubiquitous in programming sense, everything is a number.

You're also going to learn some other important lessons as you work on these problems like how to do math in Java. Whatever sorts of problems you want to solve, strings are likely to come up in them in one way or another, HTML, email or really anything that is text that is represented as a string. Of course, the lessons you will learn about working with strings and programming in general will help you far beyond this problem domain. This problem is a great one to learn on because even though we're going to start with a greatly simplified version of it, it's an important problem with real-world applications. You are going to be working with strings that represent DNA, solving problems like searching for genes in them. By the end of this module, you will be able to: (1) Use important methods for the Java String class (2) Use conditionals, for loops, and while loops appropriately in a Java program (3) Find patterns in the data represented by strings to help develop the algorithm for your program (4) Understand the importance of designing programs that keep different data processing steps separate (5) Use the StorageResource iterable for this course to store some data for further processing and (6) Rely on Java documentation to better understand how to use different Java packages and classes.

After learning about Java methods that work with strings, you will be able to find genes within a DNA string as well as tackle other string related problems, such as finding all of the links in a web page.

To tackle this problem, you will need to understand strings: series of characters such as letters, digits, punctuation, etc. This module begins with a short presentation from Raluca Gordân, an assistant professor in Duke University’s Center for Genomic and Computational Biology, about an important problem genomics scientists encounter regularly: how to identify genes in a strand of DNA.
