PPT-Question 1 : All cells on Earth use mRNA to make protein rather than using DNA directly.

cells It is not possible for protein to be made from DNA directly because DNA cannot leave the nucleus It allows for more levels of control for protein synthesis mRNA is more flexible and single stranded while DNA is doublestranded and helical and therefore its strands cannot easily be . DNA .  RNA  Protein. 2 Major Steps. Transcription. – DNA is transcribed (copied!) into single stranded mRNA . (DNA code transcribed into RNA code). Translation. – mRNA is translated into protein (amino acids). Griffith. First major experiment that led to DNA in 1928. Studied 2 strains of . Streptococcus . pneumoniae. Sugar coated strain (S) caused pneumonia. Non sugar coated strain (R) does not cause pneumonia. Chapters 16 and 17. Before the end of the semester we will be covering…. Historical DNA experiments.

What does DNA stand for?. Deoxyribonucleic acid. DNA is a polymer. What is DNA made of?. Nucleotides = monomers. Nucleotide:. Deoxyribose. sugar. Phosphate group . From DNA to Proteins. 2 Types of nucleic acid. DNA- Life’s Code. DNA. -> . RNA . -> . Protein. Influential Scientists. Frederick. Griffith. – Experimented with two forms of . bacteria. 9.1 Ricin, RIP. A tiny amount of ricin, a natural protein found in castor-oil seeds, can kill an adult human – there is no antidote. Ricin is a ribosome-inactivating protein (RIP). Inactivates the organelles which assemble amino acids into proteins. From DNA to Proteins. 2 Types of nucleic acid. DNA- Life’s Code. DNA. -> .
