One possible results of chromosomal breakage is for a fragment to join a non-homologous chromosome. What is this alteration called? - -A translocation -Which of the following is true of linkage? - -The closer two genes are on a chromosome, the lower the probability that a crossover will occur between them -The chromosomal theory of inheritance explains what? - -Mendel's laws of segregation and independent assortment -If a deletion occurs on the Y chromosome that removes the SRY gene in...

what is a basic method of extration of DNA? - -1. cells are lysed using a detergent that disrupts plasma membrane 2. cells are treated with protease to destroy protein and RNAase to destroy RNA 3. cells are put in a centrifuge and the supernantant liquid is transferred to a clean tube 4. the DNA is precipitated with ethanol, it forms viscous strands -what is restriction endonucleases? what are they key to?what are Palindromes? - -a defense system for bacteria, it recognizes and cleave a sp...

-Homologus Isolation Fossils - -preserved remains of ancient organisms -Georgraphic Isolation - -Population of speices becomes seporated by a physical boreder (mountains, rivers, land, etc.) - -structures that have diffrent mature forms but develop from same embryonic tissue -Temporal - -Isolated by time (open flower in winter, open flower in spring) -James Hutton - -Geologist who said that the forces that shaped the Earth took place over long periods of time, so the Earth had to be ...

Most likely, mitochondria and chloroplast evolved from: - -Bacteria -What three overlapping processes are involved in development? - -Growth, morphogenesis and differentiation ------ is a type of ground tissue composed of cells having tick, often lignified secondary cell walls. - -Sclerenchyma -A mature sieve element does NOT normally have: - -A nucleus -The function of companion cells is thought to be: - -Delivery of substances to sieve-tube elements -Trichomes are: - -Appendages...

matter - -anything that takes up space and has mass -elements - -any substance that cannot be broken down into simpler substances -atom - -the basic smallest unit of a matter that has all the chemical properties of an element -proton - -A positively charged particle that is part of an atom's nucleus. -neutron - -A small particle in the nucleus of the atom, with no electrical charge -electrons - -Negatively charged subatomic particles found in various energy levels (orbital shells...

What features are common to all living organisms? - -enclosed by a membrane presence of cytoplasm presence of DNA presence of ribosomes -How do electrons behave when they absorb or lose energy? - -Electrons move to higher or lower shells by absorbing (higher) or releasing (lower) energy -What is a nonpolar covalent bond? - -The atoms share the electrons equally -What is a polar covalent bond? - -One atom is more electronegative, and the atoms do not share the electron equally (crea...
