1. Prokaryotic DNA differs from eukaryotic DNA because it
a. is not a double helix.
b. consists of a single circular chromosome.
c. uses different bases.
d. consists of multiple linear chromosomes.
2. In meiosis, a mistake where homologous chromosomes do not separate properly is called _____.
a. meiotic failure
b. crossing over
c. nondisjunction
d. mitotic failure
Homework Answers
Ans-1- prokaryotes have only one circular double-stranded DNA while eukaryotes have linear DNA. Option B is correct.
Ans-2- if homologous chromosomes do not separate properly one cell has an extra chromosome while another cell has one less chromosome, this phenomenon is called non-disjunction. option C is coorect
