A strand of DNA has these bases:
 AGC CAT GTA TAC What is the complementary DNA strand?

• ACG GAT CTA TAG
• TCG GTA CAT ATG
• TGC CTA GAT ATC

Why is meiosis important for sexual reproduction?

• It allows the zygote formed from fertilization to have triple the chromosome number of the organism. 
• It allows gametes to have twice the original number of chromosomes of the organism.
• It allows gametes to have half the original number of chromosomes of the organism. 
• It allows the zygote formed from fertilization to have half the original number of chromosomes of the organism.
