Introduction Flashcards
What is the purpose of DNA?
It is used to store information that is used as a blueprint to process the synthesis for many biochemicals.
What is the role of proteins and how are they made?
Perform biological and metabolic processes. Not able to store information.
What is the RNA World Hypothesis?
The idea that the earliest life forms came from RNA.
- Can store info
- Perform biological processes
- They could possibly be the first life forms.
- Evolved into more stable DNA
What is seen as the ‘recipe book’ in humans?
The Human Genome
Which year was the draft of the human genome discovered?
- It was finally completed in 2003.
Of the 20,000 proteins known due to scientific discovery, how much of the human genome actually codes for those proteins?
1-2% of the human genome.
If there is a small difference in genome between species, what effect does this have?
Causes huge change in phenotypic characteristics. Different species can have very similar genome.
Which fruit is roughly 50% identical to the human genome?
Banana
