Quiz Flashcards
- In human, the 22 pairs of chromosomes that don’t include the sex chromosomes are called
Autosomes
- What are the replicated forms of a chromosome joined together by the centromere and eventually separated during mitosis or meiosis II? These can be first seen in propase or mitosis
SISTER CHROMATIDS
- Condition in which cells contain two sets of chromosome (2N)
DIPLOID
From fertilized egg (multicellular organisms)
GROWTH
The two steps in cell division are
NUCLEAR DIVISION AND CYTOKINESIS
Dissimilar chromosomes that determine an individual’s sex
SEX CHROMOSOMES
Meiosis creates genetic
VARIATION
- What holds together sister chromatids in prometaphase
CENTROMERE
- Any cell other than a sperm or egg cell.
SOMATIC CELL
The total hereditary endowment of a cell of a species.
GENOME
Condition in which cells contain 1 set of chromosomes (N)
HAPLOID
Human somatic cells contain how many chromosomes?
46
Most closely resembles events of mitosis except that the cells are
MEIOSIS II,HAPLOID
One of the earliest events that distinguishes meiosis occurs in prophase I and involves
PAIRING OF HOMOLOGOUS CHROMOSOMES
- A human cell has 46 total or 23 pairs of chromosomes. Following mitosis ,the daughter cells would each have a total of 46 chromosomes. After meiosis I the two daughter cells would have 23 chromosomes, and after meiosis II 23 chromosomes.
46,23,23
- Organizational unit of hereditary materials(genes) in the nucleus of eukaryotic organisms
CHROMOSOMES
Sister chromatids are pulled apart to each end of the cell.
NUCLEAR DIVISION
Unicellular organisms, division of one cell into 2 reproduces an entire organism.
REPRODUCTION
- Genomes are organized into multiple function units called.
CHROMOSOMES
Non- sister chromatids swap corresponding segments(swapping DNA between non sister)
CROSSING OVER
Is the process of cytoplasmic division and begins during telophase.
CYTOKINESIS
- A haploid reproductive cell (sperm and egg cells)
GAMETES
- Cell division function in
REPRODUCTION, GROWTH, TISSUE REPAIR
Which of the following true regarding the process of meiosis I?
CHROMOSOMES NUMBER IS REDUCED FROM DIPLOID TO HAPLOID
- Something’s wrong with this picture. What might explain the unusual patterm seen in this cell?
DURING METAPHASE ,ONE OF THE CHROMOSOMES FAILED TO BIND MICROTUBULES FROM BOTH SPINDLE POLES.
How many chromosomes are shown in this picture? How many chromatids?
8 CHROMOSOMES,8 CHROMATIDS
