Semiconservative DNA Replication — NEET Biology
📚 Practice ConceptThe scheme suggested that the two strands would separate and act as a template for the synthesis of new complementary strands. After the completion of replication, each DNA molecule would have one parental and one newly synthesised strand. This scheme was termed as semiconservative DNA replication.
A heterozygous tall pea plant (Tt) self-crosses. The 3:1 ratio is observed. Which molecular process ensures segregation of alleles into gametes?
View solution & NCERT explanation
Correct answer: B — Chromosome segregation with DNA replication ensuring allele copies
During meiosis, homologous chromosomes separate, ensuring each gamete carries one allele. DNA replication copies alleles before segregation, maintaining inheritance.
