Question | Answer |
---|---|
Chromosomes condense and form homologous pairs during this phase of meiosis. | prophase 1 |
Which base does not occur in DNA? | uracil |
Homologous chromosomes line up along the center of the cell during this phase of meiosis. | metaphase 1 |
Homologous chromosomes separate and are pulled to opposite ends of the cell during this phase of meiosis. | anaphase 1 |
How many cell divisions occur during meiosis? | two |
Both mitosis and meiosis start with this kind of cell. | diploid |
Sister chromatids line up along the center of the cell during this phase of meiosis. | metaphase II |
Sister chromatids begin to separate and are pulled to opposite ends of the cells during this phase of meiosis. | anaphse II |
A nuclear membrane forms around each set of chromatids during this phase of meiosis. | telophase II |
Meiosis forms four of this type of cell. | sex cell |
Meiosis forms cells with half the normal number of chromosomes, which is known as ____________________. | haploid |
The normal number of chromosomes is known as _____________________,, which means chromosomes in a body cell occur in homologous pairs. | diploid |
What process assures that a normal number of chromosomes occur in a zygote? | meiosis |
The cytoplasm divides and forms the daughter cells during this phase. | cytokinesis |
The new cell that forms from fertilization. | zygote |
