What is the role of telomerase in telomere length? Where is telomerase active in ? - Answer - the telomere length protects the DNA from shortening to the point it affects the gene - telomerase active cells restores the telomere length preventing it from reaching the hayflick limit - telomerase is active in cancer cells since cancer cells need to divide fast and cannot be limited by the hayflick limit, it is also active in stem cells since stem cells need to differentiate into diff tissu...

Label the Chlamydomonas cell - Answer Chloroplast - Includes chlorophyll that uses light energy to convert CO2 into sugar. Eyespot - It uses the eyespot to gather information about its environment. Flagella - Is Chlamydomonas haplontic or diplontic - Answer Haplontic - the life cycle is dominated by n (mitosis and growth occurs in the haploid form). How Chlamy grows - Answer It grows most during the G1 phase of cell division - The commitment stage is where chlamy has ...

chlamy characteristics - Answer -green algae -photosynthetic -unicellular eukaryote -eyespot -requires little space for growth, short generation time, haploid cell (easier to manipulate and keep track of one set of DNA instead of 2) what is chlamys eyespot importance - Answer -controls phototaxis=when chalky responds to light stimulus by directing flagella to move towards (+)or move away (-) the light source prokaryotes vs eukaryotes - Answer prokaryotes: -simple st...

What makes chlamy a model system - Answer -PSS does not only occur in chloroplasts -it occurs in bacteria/archea and these don't have organellels -bacteria only has 1 genome Model system because: -easy to grow (grows in liquid on a plate) -simple -small genome -can manipulate genes -reproduces fast -HAPLOID -facultatively sexual -standard eukaryotic cell -cilia and flaggela have the same developmental pathway (makes it easier to study cilia in humans) Has a genome sm...

What is photosynthesis? - Answer Light-dependent conversion of carbon dioxide into carbohydrates, an endothermic process. The carbon dioxide is reduced into glucose, and water is oxidized into oxygen. What is the structure of chloroplast? - Answer 1. Thylakoid membranes: - Light reactions - Separates the lumen (interior) from the stroma 2. The stroma: - Calvin cycle (dark reactions) 3. Circular genome (its own): - Complete with T&T (transcription & translation) - ex...

Flagellum - Answer A motility organelle that enables movement and chemotaxis- used for locomotion Eyespot - Answer Controls phototaxis - eyespot responds to light stimulus by directing the flagella to move towards or away from the light source. Chloroplast - Answer An organelle within the cells of plants and certain algae that is the site of photosynthesis, which is the process by which energy from the Sun is converted into chemical energy for growth. Nucleus - Answer ...

Compare and contrast prokaryotic vs eukaryotic transcription and translation. - Answer In prokaryotes (cells that do not have a nucleus) both transcription and translation take place in the cytoplasm of the cell. In eukaryotes (cells that have a nucleus) transcription takes place in the nucleus while translation takes place in the cytoplasm Make your "complementary base pairing" list of molecules; complete the chart to understand how signals in the DNA are "understood" i...

What minimum documentation is required to take an FAA knowledge test for any flight instructor rating? - Answer Proper identification. The preflight action required by regulations relative to alternatives available, if the planned flight cannot be completed, is applicable to - Answer any flight not in the vicinity of an airport. What requirement(s) must an authorized instructor meet in order to prepare an airplane applicant for an initial Flight Instructor Certificate? - Answer...

Category: (as used with respect to the certification, ratings, privileges, and limitations of airmen) - Answer means a broad classification of aircraft. Examples include: airplane; rotorcraft; glider; and lighter-than-air Category: (as used with respect to the certification of aircraft) - Answer means a grouping of aircraft based upon intended use or operating limitations. Examples include: transport, normal, utility, acrobatic, limited, restricted, and provisional. Class: (as ...

What data must be recorded for VOR operational check? - Answer Place of operational check Amount of bearing error Date of check Signature Indication on the magnetic compass as you roll into a standard-rate turn to the right from an easterly heading - Answer Compass will indicate the approximate correct magnetic heading if the roll into the turn is smooth Indication on the magnetic compass when turning left from a south heading - Answer Indicate a turn to the left, but ...

What type of flaps creates the least change in pitching motion? - Answer Split Which type of flaps is characterized by large increases in lift coefficient with minimum change in drag - Answer Fowler The aerodynamic forces produced by an anti-servo tab is a result of the tab - Answer Moving in the same direction as the primary control surface to which it is mounted An aircraft wing is designed to produce lift resulting from - Answer Positive air pressure below the...
