This pairing follows strict rules where <strong>A<\/strong> always pairs with <strong>T<\/strong> and <strong>G<\/strong> always pairs with <strong>C<\/strong>. When given an original strand, its complementary strand can be found by matching each base with its corresponding pair according to these rules.<\/p>\n\n\n\n<p>However, in your question, there are some characters (like &#8220;I&#8221; and &#8220;l&#8221;) that do not correspond to standard DNA bases. These may be typos, as valid DNA bases are limited to <strong>A<\/strong>, <strong>T<\/strong>, <strong>C<\/strong>, and <strong>G<\/strong>. If these characters were errors, they would need to be corrected before finding the complementary strand.<\/p>\n\n\n\n<p>This complementary base pairing is essential for processes like DNA replication, where each strand serves as a template for creating a matching strand, ensuring the genetic code is accurately passed on during cell division.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Below are DNA strands.
