Principles of Biology Exam 2 Shadwick
Three degrees of transcription: - ANS-initiation, elongation, termination
A gene that could purpose most cancers whilst found in a single copy in a cell is referred to as -
ANS-an oncogene
Anaphase (Mitosis) - ANS-Centromeres of each sister chromatid separate
Kinetochores drag daughter cells to contrary poles
Anchorage dependence: - ANS-1. Necessary for cells to unfold of divide
2. Maximum animal cells need to keep up a correspondence with a stable surface as a way to
divide
At a chiasma - ANS-two non sister chromatids are attached to every other
Cancer of the colon is resulting from - ANS-numerous somatic gene mutations
Cytokinesis (Mitosis) - ANS-Cytoplasm divides into 2 separate cells
in ANIMAL cells - cleavage furrow
in PLANT cells - vesicles converge on the arc between the two halves of the dividing mobile;
new membrane wall
Density-dependent inhibition: - ANS-if a mobile is crowded it's going to no longer divide. Cells
will forestall dividing while they're in contact with other cells
DNA replication depends on: - ANS-specific base pairing
During which degree of meiosis do synapsis and crossing over arise? - ANS-prophase I
Elongation (Transcription) - ANS-base pairing occurs (T-A, G-C)
Explain AIDS: - ANS-1. Acquired Immunodeficiency syndrome
2. It is a "retrovirus"
3. It makes DNA on an RNA template, aka Reverse Transcription
How do mutations arise? - ANS-modifications within the DNA collection resulting from some
mistakes in DNA or mutagens
