NGSS.HS-LS1-1

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

Only one strand of DNA is used as a template each time.

• replication

• transcription

Answer explanation

Correct. During transcription, only on strand of DNA contains the information in each gene. This strand serves as the template to produce RNA

What is the main purpose of transcription in cells?

• To replicate DNA

• To synthesize proteins

• To synthesize RNA from a DNA template

• To repair DNA

Compare the roles of DNA polymerase and RNA polymerase.

• Both enzymes synthesize DNA.

• DNA polymerase synthesizes DNA, while RNA polymerase synthesizes RNA.

• Both enzymes synthesize RNA.

• DNA polymerase unwinds DNA, while RNA polymerase adds nucleotides to DNA.
