What is the sequence of the bases on the opposite strand?<\/p>\n\n\n\n<p><strong><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-ast-global-color-6-color\">The correct answer and explanation is:<\/mark><\/strong><\/p>\n\n\n\n<p>The sequence of the bases on the opposite strand of DNA is <strong>TCGAGTC<\/strong>.<\/p>\n\n\n\n<p>DNA consists of two strands that are complementary to each other, meaning that the bases pair in specific ways. The four nitrogenous bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G). The base pairing follows two key rules:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Adenine (A)<\/strong> always pairs with <strong>thymine (T)<\/strong>.<\/li>\n\n\n\n<li><strong>Cytosine (C)<\/strong> always pairs with <strong>guanine (G)<\/strong>.<\/li>\n<\/ol>\n\n\n\n<p>Given the sequence on one strand is <strong>AGCTCAG<\/strong>, the opposite strand is constructed by pairing each base with its complementary partner. Let\u2019s break it down:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>A (adenine)<\/strong> pairs with <strong>T (thymine)<\/strong>.<\/li>\n\n\n\n<li><strong>G (guanine)<\/strong> pairs with <strong>C (cytosine)<\/strong>.<\/li>\n\n\n\n<li><strong>C (cytosine)<\/strong> pairs with <strong>G (guanine)<\/strong>.<\/li>\n\n\n\n<li><strong>T (thymine)<\/strong> pairs with <strong>A (adenine)<\/strong>.<\/li>\n\n\n\n<li><strong>C (cytosine)<\/strong> pairs with <strong>G (guanine)<\/strong>.<\/li>\n\n\n\n<li><strong>A (adenine)<\/strong> pairs with <strong>T (thymine)<\/strong>.<\/li>\n\n\n\n<li><strong>G (guanine)<\/strong> pairs with <strong>C (cytosine)<\/strong>.<\/li>\n<\/ul>\n\n\n\n<p>Thus, the sequence on the opposite strand will be <strong>TCGAGTC<\/strong>. This complementary pairing ensures that the DNA can be accurately replicated and transcribed, maintaining genetic integrity across generations.<\/p>\n\n\n\n<p>This pairing mechanism is essential for DNA replication. During cell division, the two strands of DNA separate, and each strand serves as a template for the formation of a new complementary strand. This process ensures that the genetic code is faithfully passed on to daughter cells.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Suppose you know that the sequence of bases on one DNA strand (one side of the DNA ladder) is AGCTCAG.
