Dna. we have heard that we are a product of our dna. but where is it? how do we "get" our dna? it is passed to us, from our parents, but in what form? several vocabulary words associated with inheritance are used interchangeably and sometimes, incorrectly. let's see if you can clear this up for someone just learning about inheritance and cell structure.
check out the illustration above. using the correct terminology, matched with the correct lettered structures, explain how all are related to inheritance.
a) this cell (b) contains chromosomes (a) in the nucleus (c). the chromosomes are made up of genes (d) that are made of short strands of dna (e).
b) in every cell on earth (b), dna (a) is found in the nucleus (c). the dna is organized into genes (d) which build chromosomes (e), which we inherit from our parents.
c) this is a cell (b) with a nucleus (c) containing dna (a). the dna is organized into chromosomes (d). a section of the chromosome that codes for a trait are called a gene (e).
d) this is a cell (b) with a nucleus (c) that contains 46 chromosomes (a). the chromosomes are the makeup of many genes (e) that, in turn, are made up of long strands of tightly coiled dna (d).
