PS & Mutations

What is the purpose of this process?

• Preserving genetic information for future generations

• Deleting the information in the sequence produced from the DNA template

• Transcribing information in the DNA sequence for use by the cell

• Producing more nucleotides for the DNA sequence

NGSS.HS-LS3-1

The mRNA strand is complementary to the DNA strand; however, uracil instead of thymine is paired with adenine.

• True

• False

Cell differentiate because...

• they contain lipids

• they clump together

• they metabolize sugars rapidly

• they have specific genes activated
