In a basal epithelial cell, chromosomes are long and uncondensed, DNA has not yet been copied, and the cell is growing and doing normal work. What part of interphase is this?
A cartilage cell has begun copying each chromosome so each one will consist of two sister chromatids. What part of interphase is occurring?
After copying is complete in a dividing marrow cell, each chromosome has sister chromatids, but the chromosomes have not condensed for division. What part of interphase is this?
Chromatin coils into visible chromosomes, the nuclear envelope begins to break down, and spindle fibers start forming. What stage of division is this?
Duplicated chromosomes sit single file at the cell's midline with spindle fibers attached from opposite poles. What stage is this?
Sister chromatids have separated and are being pulled toward opposite ends of the cell. What stage is this?
Chromosomes have arrived at opposite ends, new nuclear envelopes are forming, and the chromosomes begin to uncoil. What stage is this?
A basal skin cell produces two daughter cells with the same chromosome number and nearly identical DNA as the parent. Which process and tissue match this division?
One cell in a male gonad ultimately yields four sperm cells, each with half the parent's chromosome number. Which process and tissue produced them?
A cell in the digestive tract lining divides to replace cells shed from the surface. How do its two daughter cells compare with it?
A germ cell inside a female gonad forms one large egg cell and smaller polar bodies, all with half the chromosome number of the parent cell. Which process and tissue fit?
In a muscle fiber's nucleus, an enzyme uses one DNA strand as a template to build a complementary temporary gene copy. What process is occurring?
A strand made in the nucleus moves to a ribosome, where its base triplets specify the order of amino acids. Which molecule made that trip?
During protein building in a gland cell, one molecule matches its anticodon to a codon and brings a specific amino acid. What molecule does this?
The ribosome reads three bases at a time on a temporary gene copy. What is each three-base unit called?
After a gene copy has attached to a ribosome in the cytoplasm, amino acids are joined into a chain. What step is underway?
A cell must pass its full genome to two new body cells before tissue repair. Which event must occur before the nucleus divides?
A checkpoint defect lets an epithelial cell keep dividing even when surrounding cells signal it to stop. What is the likely tissue-level consequence?
A point mutation changes a codon in a collagen gene so a connective tissue cell inserts the wrong amino acid. What can follow in the tissue?
In a stem cell for blood, a mutation creates an early stop signal in the instructions for a membrane receptor. What consequence is most likely?
