DNA Transcription Lesson

Multiple Choice

Nucleotides are composed of a phosphate group, a 5-carbon sugar, and a nitrogenous base. DNA is made up of long strands of nucleotides.

What makes one nucleotide different from another?

• differences in the phosphate group

• differences in the pentose sugar

• differences in the nitrogenous base

• the order in which the nucleotides are arranged on one side of the DNA strand

Multiple Choice

During the cell cycle, what is the result of mitosis?

• The cell grows and performs normal cellular processes.

• The cell remains in the resting phase.

• DNA replication

• The cell separates its chromosomes into 2 genetically identical nuclei

• The cell divides into 2 genetically identical daughter cells
