<h3>Duplication requires the separation of complementary DNA strands to allow for DNA replication. </h3>
Explanation:
Several interacting forces such as Vanderwaal's forces, hydrophobic interaction and hydrogen bonds stabilize the DNA double helix structure.The strands of DNA double helix are held together by the hydrogen bond between the corresponding nucleotide bases. The separation of complimentary strands occur during replication because breaking the hydrogen bonds are comparatively easier than breaking any other bond stabilizing the DNA double helix.
Answer:
The RecBCD enzyme of Escherichia coli is a helicase-nuclease that initiates the repair of double-stranded DNA breaks by homologous recombination. It also degrades linear double-stranded DNA, protecting the bacteria from phages and extraneous chromosomal DNA.
Explanation:
The correct answer is D. Plants growth increases in the spring.
This is because observations must be objective, meaning that all people would state the same idea. This is not true for options like A and B, which are popular opinions, but definitely could be argued opinionatedly rather than with evidence that could support option D.
Hope this helps!
