chromatins can be described as... correct answers beads on a string what are the beads and strings of chromatin correct answers histones and the beads and DNA are the strings what is in the nucleus correct answers genetic materials what outlines the nucleus correct answers nuclear membrane each chromosome represents... correct answers a single linear DNA molecule nucleosomes (chromatins) are located where correct answers in the nucleus of eukaryotic cells where are histones loc...

Genome all the genetic material the organism contains Vertical transmission -from parent to offspring -same species (binary fission) Horizontal transmission -transfer of small pieces of DNA from one cell to another -different or same species 1) transformation 2) conjugation 3) transduction Transformation The process of importing free DNA into bacterial cells, cells need to be competent to do this (dead bacteria to live) Dr. Griffith -studied streptococcus ...

Which eukaryotic DNA polymerase replicates the lagging strand in the 3ʹ to 5ʹ direction? a. α b. γ c. δ d. None of the above; the lagging strand is replicated in the 5ʹ to 3ʹ direction. correct answers d. None of the above; the lagging strand is replicated in the 5ʹ to 3ʹ direction. DNA polymerases can synthesize DNA: a. de novo, by catalyzing the polymerization of free dNTPs. b. by adding dNTPs to complementary dNTPs on a single-stranded DNA. c. by adding dNTPs to a hyd...

Vertical transmission - Answer parent to offspring Horizontal transmission - Answer transfer of small pieces of DNA from one cell to another Fredrick Griffith - Answer - Studies Streptococcus pneumoniae in mice -Hypothesized that the bacteria could "transfer information" to each other Describe the complete Griffith experiment - Answer -S leads to host death -R strains are not fatal -Prekilling S strains prevent illness -Killed S plus live R is fatal Conjugation - Answer Horizon...

Which of the following statements provides the LEAST support for this idea? a. E. coli can receive plasmids from other strains of Gram-negative bacteria. b. The archaeon Methanocaldococcus jannaschii has many proteins with sequence homology to proteins found in both bacteria and Eukarya. c. Agrobacterium can transfer plasmids to plants. d. Gen...

Plasmids carrying new genetic traits can be transferred into bacteria by several methods such as heat shock. The bacteria that are transformed and contain recombinant plasmids are often identified by which process? - correct answer Exposing the bacteria to an antibiotic that inhibits cells lacking the resistant plasmid. Cells with the plasmid will be antibiotic resistant and will grow on agar laced with the antibiotic. Operons were one of the first examples of how gene expression is control...
