Homework Answers

Answer #1

a. Chargaff was able to show that DNA composition varied with different species. True

b. Replication forks are only found in prokaryotic cells. false.

c. DNA base pairing with RNA only occurs after translation in prokaryotes. False

d. Problems with DNA replication, crossing over, and DNA repair can all lead to mutations, but only somatic mutations will be passed along to future generations. false

Reason -The only mutation in the gametic cells is passed on to the next generation.

DNA Acts as a template for mRNA synthesis and mRNA acts as a template for proteins.

The replication fork is present in both prokaryotes and eukaryotes.
