A distinct sequence on a chromosome is called a ___

• Gene

• Diploid

• Sister

• Chromatin

The location that a gene occupies is a ___

• Locus

• Gamete

• Centromere

• Clone

What form are the chromosomes during interphase?

• Chromatin

• Condensed

• Haploid

• Centromered

Why is chromatin such an important molecule?

• It is condensed to allow the DNA to separate

• It can be opened to allow for transcription

• It cannot be damaged when it is in the DNA is in this form

• It allows for mutations which helps in adaptation

What occurs during g0?

• The chromosomes are duplicated

• The cell is growing to prepare for division

• The cell performs its normal designed functions

• The cell divides

Sister chromatids are ___

• Identical in every way

• Similar but not identical

• Very different

• Contains the same genes but not alleles

Sister chromatids are connected at the ___
