Answer

Slide1: The two helical strands of DNA are held together by relatively weak hydrogen bonds between the nucleotide bases. Two bonds form between adenine and thymine, and three bonds form between cytosine and guanine.

The analogy of unzipping a zipper helps explain that during DNA replication, the hydrogen bonds between the nucleotide bases are broken, allowing the two strands to separate and serve as templates for new strands.

DNA polymerase plays the role of adding new complementary nucleotides to the exposed bases on the template strand, synthesizing the new DNA strand.

It is important for the new DNA molecule to be identical to the original to ensure that genetic information is accurately passed on during cell division, maintaining the integrity of the organism's genome.

Slide2: Telomeres protect the ends of chromosomes from deterioration or fusion with neighboring chromosomes. They play a crucial role in maintaining genomic stability and are involved in cellular aging and replication limits.
