1. RNA: another nucleic acid

2. DNA

3. RNA RNA (ribonucleic acid): a nucleic acid (different from DNA)
DNA cannot leave the nucleus, so the DNA instructions are copied to another type of nucleic acid, RNA

4. Structure of RNA Sugar, phosphate group, and a base
3 Differences to DNA
DNA (deoxyribonucleic acid)
RNA (ribonucleic acid)
Double stranded
Single stranded

5. Structure of RNA Sugar, phosphate group, and a base
3 Differences to DNA
DNA (deoxyribonucleic acid)
RNA (ribonucleic acid)
Double stranded
Single stranded
Deoxyribose sugar
Ribose sugar

6. Structure of RNA Sugar, phosphate group, and a base

G, C, A, T
G, C, A, U

8. Structure of RNA In RNA thymine is replaced by uracil (U).
RNA is a disposable copy of DNA that can leave the nucleus

9. Types of RNA
Types of RNA: most RNA molecules have one job – protein synthesis (amino acids come together to form a protein)

10. Types of RNA
Types of RNA: most RNA molecules have one job – protein synthesis (amino acids come together to form a protein)
mRNA (messenger RNA) is a messenger between the nucleus and the ribosome.
codon: a 3 nucleotide sequence on mRNA that codes for a single amino acid

11. Types of RNA
Types of RNA: most RNA molecules have one job – protein synthesis (amino acids come together to form a protein)
tRNA (transfer RNA) transfers amino acids to the ribosomes to build proteins .

12. Types of RNA
Types of RNA: most RNA molecules have one job – protein synthesis (amino acids come together to form a protein)
rRNA (ribosomal RNA) forms part of the ribosome.

13. Types of RNA
