Chromatin contains DNA and proteins. Chromosomes are the x-shaped structures that strands of chromatin form into for cell division.
Chromatin is the x-shaped structures used in cell division. Chromosomes are the specific strands of chromatin used in protein production.
Chromatin is the DNA found in animal cells and chromosomes are the DNA found in plant cells.
Chromatin provides the cell with the information used in protein production, and chromosomes provide the cell with the information used in cell replication.
The sections of your DNA that provide information used to control cell division.
The collection of chromosomes you receive from each of your parents.
Are the section of DNA used to make new ribosomes.
Small sections of DNA located at specific places on a chromosome that provide the information to produce the different proteins used by your cells.
Only specific chromosomes are unwound into chromatin.
Only specific genes are read in each cell.
The chromosomes that aren't needed are made non-functional by special proteins.

A mutation is a change in which bases pair together.
A mutation is a change in the order of A,G,C, and T bases in a gene.
A mutation is a change in the number of chromosomes an individual has.
A mutation is a change in the way genes are organized on the chromosome.

Replicates its DNA, grows
Grows, replicates its DNA
Grows, replicates its DNA, and grows some more
Grows, undergoes mitosis, separates
A and T pair, and C and G pair, so the two strands from the original form a template.
Enzymes control which new bases are added to the two strands, making sure that they end up the same.
It doesn't matter if the two new helices are different - that's where genetic variation comes from.
Two copies of a DNA molecule (called sister chromatids) joined by a centromere
Two different strands of DNA (called sister chromatids) joined by a centromere.
Two different strands of DNA (called chromatids) joined by a centriole.
Two copies of a DNA molecule (called sister chromatids) joined by a centriole.
