Archaeal phylogeny - Answer Difficult to culter & PCR Genomes are recombinogenic classifications are frequently under revision Archaeal Cell Wall does not have peptidoglycan but has - Answer pseudopeptidogylcan The archaea Cell wall stains - Answer gram positive or negative the archaeal cell wall has NAG and no NAM but - Answer N-Acetyltasamunyronic acid T/F the archaeal cell wall is NOT susceptible to cell wall antibiotics - Answer True Archaeal lipids in bacteria have - Answe...

capsid correct answer- protein shell that surrounds the nucleic acid what kind of capsid do naked viruses have? correct answer- only have nucelocapsid enevelope correct answer- external covering of a nucleocapsid usually a modified piece of the host cells membrane 3 types of viral capsids correct answer- helical icosahedral complex how does the viral envelope differ from host cell membrane? correct answer- glycoproteins are exposed on the outside of the envelope helical capsi...

What kind of cells can viruses infect? ~~> viruses infect every type of cell, including bacteria, algae, fungi, protozoa, plant, and animals Are viruses alive? ~~> two sides of the debate: 1. since viruses are unable to replicate independently from the host cell, so no, not alive 2. even though viruses do not exhibit most of the life processes of cells, they can direct them, so more than inert (lacking strength/ability to move) and lifeless molecules viruses are better desc...

Naked Virus Correct Answer-A virus without an enclosing envelope, consisting only of a nucleocapsid Capsid Correct Answer-The protein shell of a virus that encloses its genetic material Icosahedral Symmetry Correct Answer-Is a limited (closed) structure and allows packaging of only limited genome sizes Quasi-Equivalence Correct Answer-The relationships between capsid proteins structures are similar but not identical Haemagglutination Correct Answer-Is a specific form of agglutination...

3 advantages of being a small cell - greater nutrient exchange, faster growth rate, higher mutation accum rate 3 features euk/prok share - cytoplasmic membrane, cytoplasm, ribosomes 3 functions of pili - surface attachment, genetic exchange, and type IV motility 3 properties of all cells - metabolism, growth, evolution 3 types of flagella and what they look like - peritrichous (on all sides), polar (one on the end), lophotrichous (multiple on end) 4 properties of only some cells - differe...

General Characteristic of a Virus CORRECT ANSWER -Can have DNA or RNA, but not both -Have no ribosomes -No ATP-generating mechanism -Are infectious Define: Obligate Intracellular Parasite CORRECT ANSWER Needs a host cell in order to replicate What is a Capsid? CORRECT ANSWER A protein coat that encloses and protects the viruses nucleic acid. -All viruses have capsids What is a Capsomer? CORRECT ANSWER Identical protein sub-units that makeup the capsid. May be made up of one or seve...

28) Viruses are not the only obligatory intracellular parasites. Describe how the replication of viruses is diferent than cellular organisms that replicate inside of cells, like chlamydiae and rickettsiae. Ans :: Unicellular parasitic cells that need to replicate inside of other cells do not replicate in the same way that viruses do. First of all, unicellular parasites have their own ribosomes to translate their mRNAs and do not use the host cell ribosomes, like viruses do. In addition they ...
