SCMH 1010 - EXAM 4 QUESTIONS ANSWERED CORRECTLY LATEST UPDATE 2026
structure of cells - Answers
nucleus - Answers part of the cell containing DNA and RNA and responsible for growth and
reproduction
organelle - Answers tiny cell structure that carries out a specific function within the cell
cell membrane - Answers controls which substances can enter or leave the cell
transport INTO cells - Answers
transport OUT of cells - Answers
respiration - Answers cells source of oxygen; endothermic & exothermic processes
metabolism - Answers process of deriving energy from the environment
cell division - Answers cell divides into two new daughter cells
mitosis - Answers cell exactly replaces itself
meiosis - Answers SEX cell replicates itself using only 1/2 of genetic information, gains other 1/2 from
another SEX cell
classical genetics - Answers traces characteristics from one individual to another; dominant versus
recessive genes
modern genetics - Answers molecular expression of genes
mendels experiments - Answers studied dominant versus recessive genes in pea plants (tall/short);
used punnett squares
DNA structure - Answers double helix; 4 bases
RNA structure - Answers single helix; uses URACIL instead of thymine
nucleotides - Answers Basic units of DNA molecule, composed of a sugar, a phosphate, and one of 4
DNA bases
bases - Answers DNA: A, G, C, T
RNA: A, G, C, U
only pair one certain bases (AT, TA, CG, CG)
helical structure - Answers outside is sugars/phosphates with nitrogen bases on inside
DNA replication - Answers The process in which DNA makes a duplicate copy of itself.
RNA replication - Answers unzips double helix and adds RNA strand to replace other strand
genetic code - Answers sequence of order of bases in humans, genes arrange themselves in different
ways in organisms, same set of chemical reactions
genomes - Answers sum total of information in genetic code
natural selection - Answers natures process of insuring characters that are fit can survive in its
species; new traits in a new environment get passed on
