WebThe DNA is copied via a process known as semi-conservative replication (semi = half) The process is called this because in each new DNA molecule produced, one of the polynucleotide DNA strands ( half of the new DNA molecule) is from the original DNA molecule being copied. The other polynucleotide DNA strand (the other half of the new … WebApr 12, 2024 · Author summary The virus chikungunya (CHIKV) that causes long term arthritis symptoms in humans is transmitted to through the bite of the Aedes aegypti mosquito. CHIKV, for which there is no vaccine, is becoming increasingly common across the globe. We therefore need to understand the mosquito’s own ability to control CHIKV, …
WebA-level Biology – DNA Replication; 2) Semi-Conservative Replication. DNA replication is semiconservative. The original strands of DNA act as a template for the synthesis of … WebSemi-conservative DNA replication. During cell division, cells need to make a complete copy of their genetic information. When DNA is replicated, the new DNA molecule is made up of one strand of the original DNA whereas the other strand is made of freshly made DNA. Since half of the DNA is preserved from the previous round of DNA replication, we …

DNA helicase breaks the hydrogen bonds between the base pairs, causing the double helix structure to unwind. Free nucleotides bind their bases to their complementary base pair on the exposed polynucleotide. Condensation reactions using DNA polymerase join the nucleotides, …
