Bio Exam 3 Questions and Answers 100% Pass What did Griffith discover in his experiment involving bacteria with capsule (S) and non-capsule (R) strains, and what molecule did Avery, MacLeod, and McCarty identify as responsible for this phenomenon? Griffith observed that DNA could transform bacteria, demonstrating for the first time that genetic material can be transferred through a process called transformation. The S-strain, with a polysaccharide capsule, is protected from the immune...

bacterial DNA 1-2 circular chromosomes, DNA is much longer than the cell, replicates right before binary fission, found in the cytoplasm Prokaryotic chromosomes circular, one origin of replication, 1000 nucleotides/second, primer removal = DNA polymerase 1, strand elongation = DNA polymerase III eukaryotic chromosomes multiple linear strands, have centromeres and telomeres, need to separate, multiple origins of replication, 100 nucleotides/second; primer removal = RNAse H; elongationpoly...

BIOD 101 PORTAGE LEARNING MODULE 6 EXAM WITH BEST SOLUTIONS What is the nucleoid region used for? - To store genetic information in prokaryotes True or false: If false, make it true. The nucleoid region is bound by a membrane and does not contain bacterial chromosomes and DNA? - False The nucleoid region is NOT bound by a membrane and DOES contain bacterial chromosomes and DNA. Bacterial chromosomes are in what shape? - Circle Define plasmids - Small, circular region of DNA. How ...

Bio 102 exam 1 WVU Salihu Latest Update 100% Pass Prokaryote evolution of cells: 3.5 billion years ago Prokaryote size of the cell: small Prokaryote unicellular Prokaryote organelles: absent Prokaryote Location of genetic information: nucleoid region Prokaryote DNA Structure: circular (usually one chromosomes) Prokaryote Reproductive strategy: asexual Prokaryote oxygen requirement: anaerobic (doesn't require oxygen) Eukaryote evolution of first cell: 1.5 billion ye...

Cell Theory - ANSWER-Discovered in the 17th century 1. All living things are composed of cells 2. The cell is the basic unit of life 3. The chemical reactions of life take place inside the cell 4. Cells arise from only preexisting cells 5. Cells carry genetic information in the form of DNA. This genetic material is passed from parent cell to daughter cell 6 Kingdoms - ANSWER-Bacteria, Archaea, Protista, Fungi, Plantae, and Animalia Prokaryotic - ANSWER-"before nucleus", lacks a memb...

Tamu Biol 111 Fletcher Final Test Questions And Verified Correct Answers Describe the basic functions all life forms must accomplish - ANSWER : -response to environmental stimuli & maintain homeostasis -uptake and processing of nutrients/energy -regulation -growth and reproduction Compare and contrast eukaryotic and prokaryotic cell types - ANSWER : Prokaryotes: -circular chromosomes, no nucleus, no organelles, 3.5 bya -DNA concentrated in nucleoid Eukaryotes: -linear chromoso...

Eukaryotes - ANSWER multicellular, complex organisms, have a proper nucleus containing genome, and organelles (lysosomes, endoplasmic reticular - smooth and rough - golgi complexes, and mitochondria), DNA = contained in multiple linear chromosomes, cells divide using MITOSIS Prokaryotes - ANSWER primitive organisms, much smaller cells, unicellular, no nucleus, genome = in nucleoid, no organelles, DNA = contained in single circular chromosome, cells divide using BINARY FISSION binary fissi...
