Answers
‣ RNA can... Answer: store information and catalyze chemical rxns
‣ ribozyme . Answer: An enzymatic RNA molecule that catalyzes
reactions during RNA splicing.
‣ RNA+protein . Answer: ribonucleoprotein
‣ ribosome function in translation . Answer: peptidyl transferase (rRNA
of large subunit) catalyzes peptide bond formations to make proteins
‣ RNA to DNA shift . Answer: via reverse transcriptase activity
‣ distinguishing factors of eukaryotes . Answer: nuclear envelope,
membrane-bound organelles, cytoskeleton
‣ eukaryotes evolved from... . Answer: archaea
‣ cytosol . Answer: The soluble portion of the cytoplasm, which includes
molecules and small particles, such as ribosomes, but not the organelles
covered with membranes.
, ‣ Where is DNA found? . Answer: nucleus, mitochondria, chloroplasts
‣ mitochondria & chloroplasts were originally . Answer: endosymbionts
‣ chloroplast membranes . Answer: inner (eukaryote-like), outer
(prokaryote-like), thylakoid (contains chlorophyll)
‣ features of organelles (evidence for endosymbiosis) . Answer: -own
DNA/genomes
-can divide independent of mitosis
-enclosed by double membranes
-cannot survive outside cell (loss of genes to nucleus)
‣ properties common to all living cells . Answer: membrane, genetic
material, cytoplasm, metabolism
‣ how did a eukaryote evolve from a prokaryote . Answer:
endosymbiosis
‣ monosaccharides formula . Answer: (CH2O)n
‣ disaccharide . Answer: A double sugar, consisting of two
monosaccharides joined by dehydration synthesis (condensation)
