the time during mitosis when sister chromatids separate
what is anaphase?
Y-linked gene that determines maleness in mammals
what is SRY?
when the two alleles of a gene are segregated into different cells at the first meiotic division
What is first-division segregation?
structures at the end of eukaryotic chromosomes
What are telomeres?
a group of three mRNA bases signifying one amino acid
What is a codon?
one diploid cell gives rise to four haploid cells
what is meiosis?
processes that equalizes the dosage of X-linked gene products in the somatic cells of males and females
What is dosage compensation?
individual composed of cells with different genotypes
what is a mosaic?
A nitrogenous base containing a double ring

chromosomes that do not differ between the sexes
What are autosomes?
tips of the X and Y chromosomes

Hershy-Chase
What is the Transformation principle?
sequences of base pairs within a gene that is not represented by any bases in the mature mRNA
What are introns?
site of the closest connection between sister chromatids
What is a centromere?
cells in the ovary that undergo meiosis
