Mutually exclusive events are those that cannot occur at the same time. In probability theory, this concept arises frequently in various scenarios. One example is the rolling of a die, where each number (1-6) is mutually exclusive to any other. Similarly, picking a card from a standard deck, the selection of one suit (e.g., hearts) … Read more
Fragments of copied DNA, also known as Okazaki fragments, are short, single-stranded segments created during the replication of DNA on the lagging strand. DNA polymerase, the enzyme responsible for synthesizing new DNA strands, can only add nucleotides to the 3′ end of an existing strand. On the leading strand, which is synthesized continuously, DNA polymerase … Read more
