DNA Replication - ANSWERDNA helicase breaks hydrogen bonds. Each strand acts as a template. Free nucleotides attach. Complementary base pairing occurs- AT and CG. DNA polymerase joins nucleotides. Hydrogen bonds reform. Semi-conservative replication- new DNA molecule contains one old and one new strand Transcription - ANSWERDNA helicase breaks hydrogen bonds between DNA strands. One strand acts as a template. RNA nucleotides attract to exposed complementary bases on DNA. RNA polymerase joins ...

gene - Answer-unit of inheritance that programs the amino acids of a polypeptide chain monomers: DNA and nucleic acids two types of DNA - Answer-DNA and RNA gene expression - Answer-DNA directs its own replication, controls protein synthesis flow of genetic info - Answer-DNA -> RNA -> Protein DNA backbone made of - Answer-sugar and phosphate complement base pairing - Answer-A w/ T and G w/ C phosphodiester linkage - Answer-links nucleotides, made of phosphate group that links the su...

Glycerophospholipids (GPLs): - amphipathic (having both hydrophilic and hydrophobic parts) are main lipid constituent of PM Contain glycerol backbone: 2 fatty acid tails in ester linkage A polar head group (that varies in size) A phosphate ester of another alcohol (choline, ethanolamine, serine, or inositol) GPLs can differ in polar head group, chain length, and saturation of bonds Common cell structures called organelles are either membrane bound or non membrane bound. Choose the follow...
