The activities in the cell cycle occur during specific phases. In which phase of the cell cycle is DNA replicated?
Mitosis
G1 phase
G2 phase
S phase
Scientists can bioengineer skin in a laboratory to treat severe burns and other types of skin injuries. This bioengineered tissue is grown from living cells. The cellular process that enables the cells to grow and develop into tissue is -
conjugation
meiosis
budding
mitosis
Gametes produced by an organism contain a combination of genes from that jorganism. In every gamete, this combination is -
the same because it is created from the same DNA
the same because chromosomes are copied prior to meiosis
different due to DNA replication prior to mitosis
different due to independent assortment during meiosis
Which diagram demonstrates how crossing-over contributes to genetic variety during meiosis?
A
B
C
D
During meiosis, homologous chromosomes exchange genetic material. This exchange of genetic material -
increases the genetic variation
reduces the diploid number to the haploid number
increases the haploid number to the diploid number
reduces the probability of mutations
Human body cells each have 46 chromosomes in their nuclei. Meiosis is necessary in order to ensure that each gamete produced in the human body has -
12 chromosomes
23 chromosomes
46 chromosomes
92 chromosomes
Sexual reproduction in animals depends on the production of gametes. Which of these processes produces gametes in animals?
Mitosis
Fertilization
Meiosis
Binary fission
Crossing-over between nonsister chromatids during meiosis is significant in heredity. This process most likely leads to an increase in which of the following?
The expression of dominant traits
Number of gametes
The occurrence of polyploidy
Genetic variation
What types of cells undergo mitosis?
sex cells
body cells
gametes
sperm and egg cells
What do the cells look like at the end of mitosis?
different from original cell
identical to the original cell
similar to the original cell
none of these
