Alanine is an amino acid required for bacteria growth. group a bacteria can make alanine hroup b ca Show more alanine is an amino acid required for bacteria growth. group a bacteria can make alanine hroup b cannot. an extract of group a is made and added to a culture of group b bacteria some of which begin to grow and reproduce.
controls of group b without the extract do not survive.. t/f 1.the process described is transformation 2. if group b were offspring of group a bacteria then the group b bacteria probably arose as a result of an error in DNA replication 3.Group b bacteria receiving the extract grew because the extract contained alanine 4.the extract probably contained DNA from group a bacteria 5.if the offspring of group b bacteria that grew after receiving the extract were placed on another medium lacking extract they would probably continue to grow reproduce and make alanine 6.the extract had to contain all amino acids 7.group b bacteria could not make an enzyme needed to make alanine Show less
