CMMB 343 Final Question and answers 100% correct 2024How does phi6 penetrate the host cell? - correct answer - because it is an enveloped phage, it uses the entry and uncoating model that relies upon spike-protein mediated endocytosis - once in the vesicles, it releases the viral particles and proteases digest the capsid coat, lysing the vesicle, and releasing the phage genome into the cytoplasm Which protein is the plug at the end of the tail tube in T4, preventing DNA from leaving the ta...

Causes of chromosomal aberrations - errors in chromosome segregation (causes whole chromosome aneuploidy) and/or DNA damage repair (causes structural variation) Anneal - the ability of two complementary nucleic acids to align in an opposing orientation to allow the nucleotide bases of one strand to form hydrogen bonds with the nucleotide bases of the complementary strand; used in microarrays to bind DNA and show fluorescence Absolute risk - A person's chances of developing a disease or dis...

SEA-PHAGES Lab Practical UPDATED ACTUAL Questions and CORRECT Answers During DNA Extraction, how is DNA separated from everything else that may be in the solution? - CORRECT ANSWER- Nuclease breaks down the bacterial DNA/RNA, but not the phage's because it is protected by a capsid. Then resin breaks down the capsid. During DNA Extraction, if the DNA wasn't added at the beginning of the protocol, what result is very likely? - CORRECT ANSWER- The bacterial DNA/RNA would still be ...
