SG 4.1

Question 1

DNA

Answer 1

• Deoxyribose = sugar
• T (A=T)
• 2 helix (2 strands)
• 1 function (one storage)

Question 2

RNA

Answer 2

• Ribose = w/out O = sugar
• U(Uracil) (A=U)
• Folds over (singular)
• multiple structures = multiple things

Question 3

Answer 3

• Phosphate group
• monosaccharide (sugar)
• Nitrogenous (Base)
• Nucleotide
• CH2
• Base pairing w/ hydrogen bonds
• sugar phosphate backbone
• A, C, G (G=C)

Question 4

Hersey-Chase Experiment

Answer 4

• Phages only injected their DNA into host bacteria, and that the DNA served as the replicating genetic element of phages.
• proved that DNA is the hereditary material.
• using radioactive sulfur and phosphorous

Question 5

Chargaff’s Rules

Answer 5

A=T, C=G

Question 6

Griffith and Transformation

Answer 6

• Bacteria are capable of transferring genetic information through a process known as transformation.
• Researching about Pneumonia
• Testing it on mice with different strains

Question 7

Avery and DNA

Answer 7

DNA was responsible for the genetic exchange of information

Question 8

DNA structure

Answer 8

Two long polynucleotide chains composed of four types of nucleotide subunits. Each of these chains is known as a DNA chain, or a DNA strand. Hydrogen bonds between the base portions of the nucleotides hold the two chains together
