• ACG-CCU-GAG-GAG

The process of creating mRNA from DNA strand is called

• replication

• transcription

• translation

The process of creating a protein from mRNA is called

• replication

• transcription

• translation

The process of creating a new DNA double helix from an older DNA molecule is called

• replication

• transcription

• translation

is the process by which DNA makes a copy of itself during cell division.

is the process of copying a segment of DNA into RNA.

the process by which a cell makes proteins using the genetic information carried in messenger RNA.

• DNA Replication

• Transcription

• Translation

Predict the consequence of a mutation that prevents the formation of the RNA primer during DNA replication.

• DNA replication would proceed normally.

• DNA replication would be initiated but not completed.

• DNA replication would not be initiated.

• DNA replication would result in incomplete RNA strands.
