◉ Nucleotide. Answer: monomer of a nucleic acid; has a 5 carbon
sugar a phosphate group, and a nitrogenous base.
◉ nucleic acid. Answer: What substances
◉ Chargaff's rule. Answer: Rule stating that the amount of
ADENINE present (in DNA) always equals the amount of
THYMINE, and the amount of GUANINE always equals the amount
of CYTOSINE
◉ Double helix, antiparallel, complementary base pairing, sugar
phosphate backbone.. Answer: Name some components of the three-
dimensional structure of DNA according to Franklin, Watson, and
Crick.
◉ Double Helix. Answer: Double stranded molecules of nucleic
acids
◉ Antiparallel. Answer: Directionality of DNA, strands are parallel
but run in two opposite directions.
, ◉ Complementary base pairing. Answer: Feature of DNA where A
pairs with T, and G pairs with C, so that the diameter of the DNA
strands remains constant.
◉ Semi-conservative DNA replication. Answer: One strand of the
parental duplex remains intact in daughter strands, with a new
complementary strand built for each parental strand consisting of new
nucleotides.
◉ Meselson and Stahl Experiment. Answer: Experiment proving that
semiconservative DNA replication involves making new strands of
DNA by separating parent strands and using them as a template to
make new DNA strands.
◉ Conservative DNA replication. Answer: Both strands of parental
duplex remain in tact, and both strands of the new DNA duplex would
contain all-new nucleotides
◉ Disperative DNA replication. Answer: Copies of DNA consist of
mixtures of newly synthesized strands; new DNA is dispersed
throughout each strand of both daughter molecules after replication.
◉ DNA. Answer: DNA or RNA? Contains deoxyribose.
◉ DNA. Answer: DNA or RNA? contains the base thymine (T)
◉ DNA. Answer: DNA or RNA? Usually double stranded
, ◉ DNA. Answer: DNA or RNA? Longer strands
◉ RNA. Answer: DNA or RNA? Contains the sugar ribose
◉ RNA. Answer: DNA or RNA? Contains the base Uracil (U)
◉ RNA. Answer: DNA or RNA? Usually single stranded
◉ RNA. Answer: DNA or RNA? Shorter
◉ DNA→RNA→Protein (DNA codes for the synthesis of
RNA)→(mRNA codes for the synthesis of protein). Answer: What is
the central dogma of molecular biology
◉ using the information contained in a gene to produce the molecule
that is active within the cell. Answer: Explain the concept of gene
expression
◉ one of the two DNA strands (antisense) is transcribed into the
coding strand (sense). Answer: Describe the general outcome of
transcription
◉ Sense strand. Answer: DNA strand that contains genetic code for
DNA (coding strand)
