What do dideoxynucleotides do when added to a growing DNA strand during Cycle Sequencing?

• They stop the elongation of that strand.

• That double the length of that strand.

• They shorten the length of the strand.

• They denature the strand.

Which of the following base pairs is matched correctly?

• Guanine and Thymine

• Cytosine and Adenine

• Adenine and Thymine

• Thymine and Cytosine

What is the purpose of Polymerase Chain Reaction (PCR) in the process of sequencing DNA?

• To separate DNA fragments by size

• To synthesize copies of template DNA

• To change the structure of template DNA

• To terminate the elongation of a DNA strand

How is DNA synthesis in PCR and Cycle Sequencing DIFFERENT?

• Only PCR uses deoxynucleotides.

• Cycle Sequencing generates DNA products of different lengths.

• Only PCR analyzes DNA products using gel electrophoresis.

• Only Cycle Sequencing uses dideoxynucleotides.

Write the correct sequence that matches this chromatogram.

Competition for food, light, and space is most severe in:

• closely related species growing in the same area or niche

• distantly related species growing in different habitats

• distantly related species growing in the same habitats

• closely related species growing in different habitats
