Can proteins have separate domains with distinct structures and functions?
yes
What is a list of the four phase of mitosis in order?
Phase 1- Mitosis begins. Chromosomes condense from long strands into rodlike structures. Phase 2- The nuclear membrane is dissolved. Paired chromatids align at the cell's equator. Phase 3- The paired chromatids separate and move to opposite sides of the cell. Phase 4- A nuclear membrane forms around each set of chromosomes, and the chromosomes decondense. Mitosis is complete.
What is the stage that chromosomes separate?
What is Half of the number of chromosomes
How do chromosomes separate?
meiosis
The failure of replicated chromosomes to separate is called?
The failure of replicated chromosomes to separate is called nondisjunction. This will cause extra or missing chromosomes in the daughter cells.
Can proteins have separate domains with distinct structures and functions?
yes
Chromosomes first become visible during which phase of mitosis?
Chromosomes first become visible during prophase of mitosis when they condense and coil up tightly. This allows them to be easily seen under a microscope as separate structures.
What structures allow chromosomes to separate and move during mitosis?
Science.
What are the 8 steps of?
Prophase I: chromosomes start to condense and become visibleMetaphase I: homologous chromosomes line up at equatorial plateAnaphase I: homologous chromosomes separate and move to diferent polesTelophase I: one set of chromosomes arrive at each poleProphase II: chromosomes condense againMetaphase II: individual chromosome line up at equatorial plateAnaphase II: centromere divides, and chromosomes (from chromatids) move to different polesTelophase II: one set of chromosome arrive at each pole.
What is a list of the four phase of mitosis in order?
Phase 1- Mitosis begins. Chromosomes condense from long strands into rodlike structures. Phase 2- The nuclear membrane is dissolved. Paired chromatids align at the cell's equator. Phase 3- The paired chromatids separate and move to opposite sides of the cell. Phase 4- A nuclear membrane forms around each set of chromosomes, and the chromosomes decondense. Mitosis is complete.
Four phases of mitosis and explain?
Prophase metaphase anaphase and telophase 1 chromosomes condense from long strands into rodlike structures 2 nuclear membrane is dissolved and bro Aries align at cells equator 3 chromatids separate and move to opposite sides of the cell 4 a nuclear memrane forms around each set of chromosomes, they unwind afterwards.
The phase of mitosis during which chromosomes become visible and the centrioles separate from one another is?
Prophase. The chromosomes become more conspicuous because they gradually condense during prophase. The centrioles separate in animal cells; plant cells lack centrioles.
Describe the two stages in meiosis?
there are actually four stages or phases in meiosis: prophase, metaphase, anaphase and telophase. Within prophase there is the leptotene stage where individual chromosomes condense into strands within the nucleus, the zygotene stage where the chromosomes line up with each other into homologous chromosomes, the pachytene stage where the nonsister chromatids exchange genetic information over regions of homology, the diplotene stage where the chromosomes start to separate and uncoil a little to allow some transcription of DNA, and the diakinesis stage where the chromosomes condense further and the meiotic spindle begins to form.
A country broken into separate political entities is said to be?
A country broken into separate political entities is said to be fragmented. It may have different regions or groups that have distinct political systems or governing structures.
How does the appearance of the chromosome change through division?
first it becomes two chromatids, then during prophase, chromosomes condense from long strands into rod like structures. During METAPHASE paired chromatids align at the cell's equation. Then during ANAPHASE the paired chromatids separate and move to the opposite side of the cell. During TELOPHASE a nuclear membrane forms around each set of chromosomes, and the chromosomes decondense.
What is the stage that chromosomes separate?
What is Half of the number of chromosomes
What type of chromosomes separate during mitoses?
Both autosomes and sex chromosomes separate during mitosis./ Somatic chromosomes separate during mitosis with same number as in the parent cell.
