Photosynthesis converts carbon dioxide and water into oxygen and glucose
The main function of cladodes is : Photosynthesis
Cladodes are a type of modified stems that has a flattened form like leaf. The function is actually also to replace the leaves in photosynthesis process. Hope this helps
Answer:
The correct options are:
a) The ability to halt the cell cycle in response to DNA damage.
c) The ability to repair DNA damage.
e) The ability to stimulate cell death processes if the cell is irreparably damaged.
Explanation:
p53 gene has been called 'the guardian of the genome' because its prevents genome mutations which can bear to tumor formation. The main roles of p53 are:
DNA repair (option c): it activates a ribonucleotide reductase which is involved in DNA repair when it is damaged.
Growth arrest (option a): it avoids the cycle cell progression when a damage occur.
Apoptosis (option e): it induces programmed cell death or apoptosis (because every cell must die eventually).
These processes are involved in prevention of tumor formation through activation/inhibition patways which in last instance prevent the replication of cells with a damaged/mutated genome.
