Subject:
1. Semiconservative replication of DNA refers to the fact that A. the daughter DNA is an entirely new duplex and thus the original DNA is intact. B. pieces of the old and new DNA duplexes are jumbled together in the daughter generation. C. each strand of the parent DNA serves as a template for the synthesis of its new partner strand. Thus, one strand is conserved in each new double helix. D. DNA replication is modest in its ATP requirements. E. DNA replication occurs by base pairing between adenine and thymine and between guanine and cytosine. 2. The following statements about the codon are true EXCEPT A. the codon is a triplet of nucleotides on messenger RNA (mRNA). B. the codon is a triplet of bases on transfer RNA (tRNA).
