Biology Section 23: Reactions

haploid – cell with half the number of chromosomes (n) as a diploid (2n) cell
glycolysis – Breakdown of glucose to Pyruvic Acid
RNA polymerase – An enzyme that links together the growing chain of RNA nucleotides during transcription, using a DNA strand as a template.
Describe what might happen to the resulting protein if some of the nitrogen bases in the transcribed DNA molecule were reversed. – If some of the nucleic acids were reversed in a DNA molecule, then it may code for a different amino acid and the protein may not function.
spindle fiber – What structure is produced when protein fibers radiate from centrioles?
tropism – A growth response that results in the curvature of whole plant organs toward or away from stimuli owing to differential rates of cell elongation.
Golgi Apparatus – stack of membranes in the cell that modifies, sorts, and packages proteins from the endoplasmic reticulum
The outer protective layer of the eye is the
Nucleolus – – dark area in the nucleus where DNA encoding ribosomal RNA and proteins are located
homologous structures – Similar body parts on organisms of different species, but sometimes serve different functions.
Anthrax – a bacterial disease caused by Bacillus anthracis; typically a disease of farm animals; has been used in terrorist attacks
The оuter prоtective lаyer оf the eye is the
evolutionary tree – A branching diagram that reflects a hypothesis about evolutionary relationships among groups of organisms.
