BLUEPRINT OF LIFE sample ppt for gr. 10.pptx

for simple discussion

1. the blueprint of life topic #1

2. define DNA, differentiate dna and rna identify the role of DNA and RNA in protein synthesis, and analyze the importance protein synthesis in the human body. learning targets:

3. DNA Deoxyribonucleic Acid Sugar macro-molecule [ stores the genetic material ] DNA stands for deoxyribonucleic acid. It is a long molecule made up of monomers called nucleotides which are made up of: PHOSPHATE GROUP 2. NITROGENOUS BASE 3. DEOXYRIBOSE SUGAR

4. DNA contains the instructions needed for an organism to develop, survive, and produce. it is described as the “ blueprint of cell”, because it commands what protein should be used in order to build a cell. it dictates the shape of your face, eye color, and skin complexion. Deoxyribonucleic Acid ‘di na ako

5. DNA is in every cell of every living thing. It is found within the chromosomes of the cell. Chromosomes work to build proteins and assist in duplication or division of the cells. Where is DNA found?

6. The unique structure of DNA allows it to be the hereditary molecule and allows it to store instructions for directing cell activities.

7. The twisted ladder shape is called a double helix.

8. NITROGEN BASES Adenine Thymine Cytosine Guanine PURINE TWO RING STRUCTURE PYRAMIDINE SINGLE RING STRUCTURE

9. The backbone of DNA is formed by alternating sugar and phosphates held together by a strong bond. Nucleotide The rungs of the ladder are formed by the four nitrogen bases and are held together by weak hydrogen bonds.

10. Adenine Thymine Cytosine Guanine The bases of DNA pair with each other in a predictable way. A ALWAYS PAIRS WITH T C always pairs with G What does dNA look like?

11. How does DNA work? The 4 letters of DNA make up codons. These chemicals are repeated in various orders over and over. These codons make up genes. These genes tell cells how to make a protein that controls everything in the cell.

12. RNA ribonucleic Acid RELAPSE na ako

13. RNA ACTS AS AN INTERPRETER TO THE DNA IN ORDER TO MAKE PROTEIN THAT IS TO BE SYNTHESIZED. SINGLE STRANDED. COMPOSED OF SUGAR RIBOSE, PHOSPATE AND NUCLEIC BASIS. FUNCTIONS IN PROTEIN SYNTHESIS TRANSCRIBING AND TRANSLATING GENETIC CODE. HAS URACIL INSTEAD OF THYMINE. ribonucleic Acid RELAPSE na ako
