5 True/False questions
Nucleus (Eukaryotic cells) → houses chromosomes (DNA + chromatin - protein), and nucleolus - site of ribosome parts assembly, in an membrane = nuclear envelope
Atomic Number= → number of protons
Atomic Mass=...=... → number of protons
Levels of Protein structure → Primary structure = sequence of amino acids
Secondary structure = coiling to form an alpha helix or folding to form a pleated sheet - hydrogen bonding may be involved
Tertiary structure - Overall, 3 - D shape, usually described as fibrous or globular
Quaternary structure - many proteins have multiple peptide chains or subunits - how these fit together is called quaternary structure
Common Features of life → Order, regulation, growth & development, energy processing, response to the environment, reproduction, evolutionary adaptation
