PROTEIN

1. SCIENCE 10 Quarter 3 Week 5

2. LET’S RECALL W hat are genes? How about chromosomes ? The chromosome is made up of DNA. What is DNA ? The DNA has an important role in the making of a protein. What is protein ?

9. MELC: Explain how protein is made using information from DNA ( S10LT-IIId-37) LEARNING OBJECTIVES: 1.Explain protein synthesis 2.Describe the stages of protein synthesis. 3.Appreciate the importance of protein in living organisms.

10. STAGES OF PROTEIN SYNTHESIS

11. TWO MAIN TYPES OF NUCLEIC ACIDS DNA R NA DEOXYRIBONUCLEIC ACID RIBONUCLEIC ACID

12. DNA R NA No. of Strand Location in the Cell Type of Sugar Nitrogenous Bases 2 nucleus deoxyribose A,T,C,G 1 cytoplasm ribose A,U,C,G

13. THREE KINDS OF RNA A.Messenger RNA (mRNA) Brings information from the DNA in the nucleus to the protein manufacturing area, the cytoplasm. B.Ribosomal RNA ( rRNA ) ribosomes which is made of rRNA and the ribosomal proteins hold tightly into the mRNA using its information to assemble the amino acids in correct order. C. Transfer RNA ( tRNA ) - Supplies amino acids to the ribosome to be assembled as protein.

14. THREE KINDS OF RNA

15. describes the flow of genetic information in cells from DNA to RNA to protein. CENTRAL DOGMA

16. DNA REPLICATION REPLICATION – is the process of making copies of DNA. is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules . When DNA replicates, two identical copies of DNA molecules are produced, which is exactly the same as the original.
