Mucoid trichocysts are elongated inclusions that may be ejected as visible bodies after artificial stimulation. Filamentous trichocysts in Paramecium and other ciliates are discharged as filaments composed of a cross-striated shaft and a tip.
Answer:
e. 1/2; semiconservative
Explanation:
1/2 (proportion) of DNA molecules (each molecule is double stranded not single stranded) will contain any radioactivity after two rounds of replication.
This experiment also demonstrates that replication is semiconservative
.
DNA replication is semi-conservative because each helix that is created contains, one strand from the helix from which it was copied.
