During DNA replication, the hydrogen bonds must be broken between the complementary nitrogenous bases in the DNA double helix
In semiconservative DNA replication, each new double helix that will form will have 1 polynucleotide strand that is from the old DNA molecule and is an Old or Parent strand, and will have a polynucleotide strand from the newly synthesized one, the new DNA strand.
Answer:
natural selection and adaptation
I believe that the best answer for this question would be spirillum. Spirillum is a genus of bacteria within the family of Spirillaceae. Typically, they are big, elongated, rigid, and spiral-shaped. Some have flagella tufts at either end. They are typically found in still freshwater. Hope this helps.
