Chapter 12 DNA and RNA Test

RNA polymerase has to bind to DNA for an enzyme to be synthesized.

• True

• False

The only function of RNA polymerase is to control mRNA synthesis in eukaryotes

• True

• False

One strand of a double-stranded DNA helix is oriented in the 5' (carbon of the deoxyribose molecule) to 3'

direction, while the complementary strand it is bonded to is oriented in the 3' to 5' direction

• True

• False

The central dogma means that environmental factors have no influence on the transcription and translation of

genes.

• true

• false

The enzymes involved in DNA replication are named for the tasks they perform.

• true

• false

DNA nucleotides are always added to an existing strand at the 3-prime end. This means that during replication a leading and lagging strand arc created.

• true

• false

DNA is a structurally simpler molecule than protein

• True

• False
