Abiochemist isolates, purifies, and combines in a test tube a variety of molecules needed for dna replication. when she adds some dna to the mixture, replication occurs, but each dna molecule consists of a normal strand paired with numerous segments of dna a few hundred nucleotides long. what has she probably left out of the mixture? a) dna polymerase b) dna ligase c) nucleotides d) okazaki fragments e) primase

DNA replication requires a few things:

1. a template

2. DNA polymerase

3. some sort of primer which binds to the DNA to get it started

4. oligonucleotides (to add as the replication occurs)

5. a ligase to complete any fragmented DNA

So, if the biochemist added some stuff but doesn't really get replication to occcur, he/she probably left out the DNA ligase

some scientists like gregory adcock agree with thorne's theory of regional continuity.

others, like chris stringer and ian tattersall, believe thorne's results may be contaminated or misinterpreted.
