What is transposition in genetics? Movement of a chromosome piece to
another
chromosome location.
Who discovered transposition? Barbara McClintock in 1950.
What are transposable elements? Genes or small DNA fragments that can
move to a
new location.
What is a gene? A segment of DNA that directs protein
synthesis.
What is the role of DNA in DNA encodes hereditary information and
inheritance? directs
the development of traits.
What are the components of DNA consists of nucleotides, each
DNA? containing a
nitrogenous base, a sugar, and a
phosphate group.

paired in DNA?
What is the process of DNA The parent molecule unwinds, and two
replication? new
daughter strands are built based on
base-pairing
rules.
What is the sequence in protein DNA provides code to form mRNA, which
synthesis? attaches
