ADN

2. DNA (deoxyribonucleic acid)
• Polynucleotide formed from covalently linked deoxyribonucleotide
units. It serves as the store of hereditary information within a cell and
the carrier of this information from generation to generation.

3. Nucleotides
• A nucleotide is the basic
structural unit and building
block for DNA and RNA. These
building blocks are hooked
together to form a chain of
DNA. A nucleotide is
composed of 3 parts:
* Five-sided sugar
* Phosphate group
* Nitrogenous base

10. Transcrition and traducction

15. • DNA is transcribed to RNA
• Most RNA is single stranded
• RNA uses uracil in place of thymine
• RNA uses ribose in place of deoxyribose

16. • Messenger RNA (mRNA)
• Contains information transcribed from DNA
Ribosomal RNA (rRNA)
• Main component of ribosomes, where polypeptide chains are built
Transfer RNA (tRNA) • Delivers amino acids to ribosomes
