Practise MYP Biology questions on 5.1 DNA and review the explanations to check your understanding.
Use these questions for topic practice and to find ideas you want to revisit in your notes or lessons.
DNA is organized into large, tightly packaged structures called __________ to ensure that all the genetic information can fit inside the cell's microscopic nucleus.
Which of the following best describes the role of DNA in the maintenance of a living organism?
True or False: A protein only becomes functional after the polypeptide chain folds into a specific shape.
How does semi-conservative replication ensure that daughter cells receive accurate genetic information for mitosis?
True or False: mRNA is a permanent copy of genetic instructions that remains inside the nucleus for the life of the cell.
chromosomes
ribosomes
nucleotides
polypeptides
Providing energy for cellular movement
Transporting oxygen to the various tissues
Acting as a structural barrier for the cell membrane
Storing instructions for enzyme shape and blood type
True
False
True
False
By creating mRNA instead of DNA during the division process
By discarding the old strands and building two entirely new molecules
By using three strands of DNA to check for errors
By pairing each original template strand with a perfectly matched new strand
