Bio 210 Exam 1 Study Guide Questions with
Complete Solutions
Types of isomers - Geometric (different atom arrangement around the c=c bound),
- Trans (linear backbone),
- Cis (bent backbone),
- Enantiomers (mirror images L isomer and D isomer)
Functional groups identification - The brain of the biomolecules, and are attached to the
hydrocarbon backbone.
- Business end of the biomolecule,
- small portions of the molecule hanging off on its surface.
Biological macromolecule synthesis Dehydration synthesis (Lose water when combining
monomers, energy is required)
Biological macromolecule breakdown Hydrolysis (Splitting water to form monomers,
energy is released)
,Types of nucleic acids DNA, RNA
Types of RNA mRNA, tRNA, rRNA
What's the covalent bond (description of the bond) that forms the basis of the sugar-phosphate
backbone of the DNA and RNA macromolecules? Phosphodiester bond (bond between
sugar and phosphate in order to build the cell's nucleic acid)
Purine Adenine, Guanine
Pyrimidine Cytosine, Thymine, Uracil
DNA and RNA purines A, G; A, G
DNA and RNA pyrimidines C, T; C, U
, Sugar in DNA and RNA Deoxyribose; Ribose
DNA double helix stabilization Hydrogen bonds
Chromatin Complex of DNA and proteins
Gene Unit of heredity
Chromosome Thread-like structure of nucleic acids and protein
What's the monomer of DNA or RNA called? Nucleotide
What does it mean to say that the DNA strands in the double helix are antiparallel?
Strands run in opposite directions, this is crucial for DNA replication
What's the monomer of proteins called? Amino acid
