7.1.1 Describe the structure of DNA‚ including the antiparallel strands‚ 3’-5’ linkages and hydrogen bonding between purines and pyrimidines. DNA is made up of two strands. At one end of each strand there is a phosphate group attached to the carbon atom number 5 of the deoxyribose (this indicates the 5’ terminal) and at the other end of each strand is a hydroxyl group attached to the carbon atom number 3 of the deoxyribose (this indicates the 3’ terminal). The strands run in opposite directions

feedback mechanisms? D) Negative feedback mechanisms work to prevent sudden severe changes within the body. Which of the following is a concept of the cell theory? D) A cell is the basic structural and functional unit of living organisms. The RNA responsible for bringing the amino acids to the "factory" site for protein formation is the: C) tRNA. If a tRNA had an AGC anticodon‚ it could attach to a(n) ________ mRNA codon. A) UCG The term used to describe the type of solution in

very similar to DNA‚ called mRNA or messenger RNA‚ is a copy of a gene‚ and serves this function the "bridge" between DNA and protein: The Central Dogma:DNA encodes the information to make RNA and RNA molecules function together to make protein | II. What is RNA and how is it different from DNA? Two big differences between DNA and RNA: * 1. The sugar in DNA is deoxyribose; in RNA it is ribose * 2. The nitrogenous base uracil (U) is used in RNA

It is important to note that though Woese defined the archaea in 1977 they would not be accepted as a separate domain of life from bacteria until the mid 80s
