Indicate the correct letter for each question below B1. In the figure, which line shows the growth of an obligate aerobe incubated B2. In the figure, which line best depicts an obligate anaerobe in the presence of 0 in e gure.which in st depics anaerobically? 02? 83. In the figure, which line best depicts a psychrotroph i incubated at 0 C? C. Time me the three basic building blocks of DNA. ou start with 3 double stranded DNA fragments, after 4 cycles of PCR you will have ...fragments about.blankExplanation / Answer
1) explain why hyperthermophile is unlikely to be human pathogens? Hyperthermophile is unlikely to be human pathogens because human body temprature is 37c which is not favourable environment for hyperthermophile which has an optimun growth at 80 c. 2)define 3 out of 5? a)Transcription:it is the process of making anRNA copy of a gene sequences, this copy called a messenger RNA molecule, it is the first step of gene expression in which a particular segement of DNA is copied into RNA by enzyme RNA polymerase, b)Translation: it is the process of translating the sequence of the messenger RNA molecule to a sequence of amino acids during protein syntheis. c) Transduction: it is the process by which foreign DNA is introduced into a cell by a virus or viral vector . 3)what is biofilm? The slimly layer is actually a group of organsims collectively callaed a biofilm,bacteria forms biofilms protection from harmfulconditions in the host and colonization, and to form community and also it is defacult mode of growth,the biofilms forms on most extreme environment and also on virtually every nonshedding surface in non sterile aqueous or humid environments. 4)(6) Ecoil is used in biotechnology because of its rapid reproduction and small size, and enormous number of cells can be grown quickly so that even a very rare mutations will appear in a short period of time and the colony formation makes it easy to isolate genetically pure strain of the bacteria. 15) Bacterial chromosome has several origin of replication: option is b that is false because most bacteria have a single circular molecule of DNA and typically only a single origin of replication. 16) option a. 17) option b. 18)option b , thymine is not present in the RNA because uracil is enerhetically less expensive to produce than thymine. 19) option a. 20) option b.( halophiles).
