Straighterline Microbiology Final Exam 2024
Questions With 100% Correct Answers
Graded A+.
1. Phylogeny - ANSWER The evolutionary history and relationships
among species or groups of organisms, often represented in a
diagram called a phylogenetic tree.
2. Horizontal Gene Transfer - ANSWER The process by which an
organism incorporates genetic material from another organism
without being the offspring of that organism, complicating the
understanding of evolutionary relationships.
3. binomial nomenclature - ANSWER two-word naming method used
to identify organisms by their genus and specific epithet.
4. rRNA Sequencing - ANSWER A molecular technique used to
determine the sequence of ribosomal RNA (rRNA) genes, which
helps in identifying and classifying organisms, particularly bacteria
and archaea, based on their genetic relationships.
5. Serological tests - ANSWER Laboratory techniques that detect the
presence of specific antibodies or antigens in a blood sample,
1
, aiding in the diagnosis of various diseases and the assessment of
immunity.
6. hexose D-glucose - ANSWER most abundant monosaccharide in
nature
7. Monosaccharides - ANSWER simple sugars, they are the building
blocks (monomers) for the synthesis of polymers or complex
carbohydrates.
8. Glycosidic Bond - ANSWER A type of covalent bond that links
monosaccharide molecules together to form disaccharides or
polysaccharides, occurring between the hydroxyl groups of two
sugar molecules.
9. Cyclization - ANSWER The chemical process by which a linear
monosaccharide molecule forms a ring structure, which is more
stable and common for sugars with four or more carbon atoms.
10. Disaccharide - ANSWER Formed when two monosaccharide
molecules chemically bond
11. Polysaccharides - ANSWER AKA Glycans. Large polymers
composed of hundreds of monosaccharide monomers
