What is the structure of DNA during interphase?
During interphase, the cell’s DNA is not condensed and is loosely distributed. A stain for heterochromatin (which indicates the position of chromosomes) shows this broad distribution of chromatin in a mouse cell (upper left). The same stain also shows the organized, aligned structure of the chromosomes during mitosis.
How are the DNA strands in interphase?
What happens when DNA goes through 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.
Which of the following is true of DNA during interphase?
Which of the following is true of DNA during interphase? It exists as chromatin and is unavailable for gene expression. Chromatin is the term for the loosely coiled DNA observed in cells during interphase. Even during interphase, however, parts of the chromosome may still be rather tightly coiled and packed.
What occurs during interphase quizlet?
What happens during Interphase? The cell grows, replicates its DNA, and prepares to begin mitosis. The spindle fibers SPLIT APART the sister chromatids and move them to opposite ends of the cell, equally dividing the genetic material.
What event occurs during interphase?
During interphase, the cell grows and the nuclear DNA is duplicated. Interphase is followed by the mitotic phase. During the mitotic phase, the duplicated chromosomes are segregated and distributed into daughter nuclei. The cytoplasm is usually divided as well, resulting in two daughter cells.
Which of the following processes happen during interphase?
During interphase, the cell grows (G1), replicates its DNA (S) and prepares for mitosis (G2). A cell in interphase is not simply quiescent. In interphase, the cell gets itself ready for mitosis or meiosis.
Are chromosomes visible in interphase?
During interphase, individual chromosomes are not visible, and the chromatin appears diffuse and unorganized.
What happens during interphase the mitotic spindle forms?
Cells spend most of their lives in interphase, specifically in the S phase where genetic material must be copied. During the S phase, DNA is duplicated into two sister chromatids, and centrosomes, which give rise to the mitotic spindle, are also replicated.
What types of activities are going on in a cell during interphase?
What type of activities are going on in a cell during interphase? The cell is actively synthesizing proteins and carrying out its normal functions. It duplicates DNA and prepares for division. Criticize this statement: Interphase is a “resting period” for the cell before it begins mitosis.
