Study Notes
RNA World Hypothesis
- Proposes that the earliest forms of life utilized RNA instead of DNA for both storing genetic information and facilitating chemical reactions.
- Suggests that RNA played a dual role in early biochemical processes, serving both as a genetic material and as a catalyst.
Structure of RNA
- Composed of nucleotides, which are essential building blocks.
- Each nucleotide consists of:
- A ribose sugar
- A nitrogenous base
- A phosphate group
Nitrogenous Bases in RNA
- Four main nitrogenous bases are present in RNA:
- Adenine (A)
- Guanine (G)
- Uracil (U)
- Cytosine (C)
- Uracil replaces thymine, which is found in DNA.
Presence and Significance
- RNA is found in all living organisms and many viruses, indicating its fundamental role in cellular processes.
- Central to various biological functions, including protein synthesis and regulation of gene expression.
Nutritional Benefits of Moringa Leaves
- Moringa leaves are nutrient-dense and offer a wide array of health benefits.
- These leaves contain seven times more vitamin C than oranges, supporting immune function and skin health.
- Moringa offers four times the vitamin A found in carrots, promoting good vision and immune health.
- Calcium content in moringa is four times that of milk, essential for strong bones and teeth.
- Moringa leaves provide three times the potassium of bananas, important for heart health and regulating blood pressure.
- They contain double the protein of yogurt, aiding in muscle repair and overall growth.
