What else can I help you with?
What do chromosomes do for the cell?
it moves stuff around the cell
What is the structure that moves the chromosomes into position and then pulls them apart?
Spindles
During cell division what moves chromosomes into position?
The spindle fibers, which are made of microtubules, help move the chromosomes into position during cell division. These fibers attach to the chromosomes and pull them apart to ensure each daughter cell receives the correct number of chromosomes.
What discovery in the 1900 supported Mendel's ideas?
Chromosomes
How many chromosomes do lobsters have?
A lobster has 100 chromosomes. Humans have 46 chromosomes, the same as a lizard. A dog has 78 chromosomes, and a fly has 12 chromosomes.

What protein structure moves chromosomes?
The motor protein structure that moves chromosomes during cell division is called the kinetochore. It forms on the centromere of the chromosome and interacts with microtubules to facilitate chromosome movement. The coordinated activity of kinetochores in the cell ensures accurate segregation of chromosomes during mitosis.

What the mitotic spindle made of?
Microtubules from the cytoskeleton of the cell
All chromosomes except the X and Y sex chromosomes are called?
homologous chromosomes and autosomal chromosomes
What does the process of cell division leads to?
There are two types of cell division in people, mitosis and meiosis. In Mitosis, the cell copies all its DNA etc, then moves chromosomes around, replicating them. These new chromosomes are then put into a new cell as the cell divides. this cell dividing or "splitting in two" is called cytokinesis. In Meiosis, gametes or sex cells are made. The same processhappens as before, but both sets of chromosomes divide again, producing 4 sex cells with 23 chromosomes in each.

Are sex chromosomes called homozygous chromosomes?
No, sex chromosomes are not referred to as homozygous chromosomes. Homozygous chromosomes have identical alleles at a specific gene locus, while sex chromosomes determine an individual's biological sex. In humans, sex chromosomes include X and Y chromosomes.
The stringy structures in the cell nucleus that contain DNA are?
chromosomes
What are chromosomes in?
chromosomes are in cells
