Telophase: The chromosomes reach either end of the cell. The nuclear membrane forms again and the cell body splits into two (cytokinesis). At the end of mitosis, one cell produces two genetically identical daughter cells.
What is the result when single cell reproduces by mitosis?
In single-cell organisms, mitosis is the only form of cellular reproduction. One round of mitosis yields two genetically identical cells. … Cells that undergo mitosis duplicate their chromosomes, resulting in cells with two times their normal haploid or diploid numbers (4N chromosomes).
Which situation is most likely to result in a mutation that is passed on to an offspring?
A human gene is inserted into a bacterial plasmid. Which would most likely produce a mutation that is passed on to offspring? A gamete with an extra chromosome forming.
Which is one reason scientists produce transgenic organisms?
It allows gametes to have twice the original number of chromosomes of the organism. It allows gametes to have half the original number of chromosomes of the organism. It allows the zygote formed from fertilization to have half the original number of chromosomes of the organism.
What will most likely be the result if all of the chloroplast are removed from a plant cell?
In the process of photosynthesis sunlight is absorbed by the chloroplasts to make sugar. Therefore, if chloroplast is taken out of the cell, the green plant will not be able to carry out the process of photosynthesis which means the plant will die.
Which is the correct order of cell mitosis?
Today, mitosis is understood to involve five phases, based on the physical state of the chromosomes and spindle. These phases are prophase, prometaphase, metaphase, anaphase, and telophase.
What is most likely to result when a mutation affects a DNA sequence?
Answer: The amino acid sequence will be changed and a different protein will be formed.
Which explains why the nuclear membrane breaks down during mitosis?
√B-The chromosomes are replicated. If a daughter cell has 50 chromosomes after mitosis, how many chromosomes were in the parent cell? Which explains why the nuclear membrane breaks down during mitosis? A-So the cytoplasm can be divided.
Which of the following would most likely result in an abnormal chromosome number?
Which of the following would MOST likely result in an abnormal chromosome number? failure of homologous chromosomes to separate during meiosis.
What is the purpose of transgenesis?
Transgenesis allows improvement of nutrients in animal products, including their quantity, the quality of the whole food, and specific nutritional composition. Transgenic technology could provide a means of transferring or increasing nutritionally beneficial traits.
How is transgenesis done?
Transgenesis is a mode of experimentation involving insertion of a foreign gene into the genome of an organism, followed by germ-line transmission of the gene and analysis of the resulting phenotype in the progeny. Transgenesis can be used to induce the expression of an exogenous gene of interest.
