What is a karyotype used for quizlet?

A karyotype is a test to identify and evaluate the size, shape, and number of chromosomes in a sample of body cells.

Which of the following is a correct statement about the events of the cell cycle?

Answer Expert Verified. The answer which is a correct statement about the events of the cell cycle is 4) Interphase consists of the G1, S phase, and G2 phase – it also consists of G0 phase, but that is not included in this option.

What event happens during interphase?

During interphase, the cell grows and makes a copy of its DNA. During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells.

What is the meaning of interphase?

: the interval between the end of one mitotic or meiotic division and the beginning of another.

What does a sister chromatid look like?

A sister chromatid refers to the identical copies (chromatids) formed by the DNA replication of a chromosome, with both copies joined together by a common centromere. The two sister chromatids are separated from each other into two different cells during mitosis or during the second division of meiosis.

What is the difference between a chromosome and a sister chromatid?

Chromosomes are not the exact copies of one another. One copy of the gene comes from each parent to the organism. Sister chromatids, on the other hand, are identical copies of one another. Chromosomes contain centromeres.

Is a chromatid half a chromosome?

A chromatid is one of two identical halves of a replicated chromosome. During cell division, the chromosomes first replicate so that each daughter cell receives a complete set of chromosomes.

What is the importance of kinetochore?

The kinetochore assembles on the centromere and links the chromosome to microtubule polymers from the mitotic spindle during mitosis and meiosis. Its proteins also help to hold the sister chromatids together and play a role in chromosome editing.

How many kinetochores are in a cell?

two kinetochores
