What is DNA Flashcards
What is DNA
the control molecule of life and has two major functions
What are the two major functions of DNA
Controls cellular activities including reproduction
makes exact copies of itself
How does DNA control cellular activites
DNA carries a CODE. Genetic instructions are encoded in the sequence of bases strung together in DNA.
DNA from male and DNA from female together become the genetic information of offspring in sexual reproduction.
What process does DNA go through to make copies of itself
Replication
What does DNA undergo
DNA UNDERGOES MUTATIONS
mutations and recombinations in the structure and number of DNA molecules are the reason for life’s diversity
Evolution, in essence, proceeds from the level of DNA. Different combinations of DNA sequences due to mutations and sexual reproduction explain the existence of all the different species that have lived on this Earth.
