Chromosomes- genetic material that is coiled up into structures during cell division. Importance of DNA- genes control the production of proteins..(look like‚ body function‚ body communications‚ and enzyme control) DNA screening- the process of testing individuals to determine whether they have the gene(s) associated w/

single cell to divide and produce all the differentiated cells in an organism‚ including extraembryonic tissues. Totipotent cells formed during sexual and asexual reproduction include spores and zygotes. Zygotes are the products of the fusion of two gametes. In some organisms‚ cells can dedifferentiate and regain totipotency. For example‚ a plant cutting or callus can be used to grow an entire plant. Human development begins when a sperm fertilizes an egg and creates a single totipotent cell called

Biology- Animal cell The NUCLEUS is the largest organelle in the majority of cells. It contains genetic information in DNA‚ which is responsible for the cells unique characteristics. The nucleus is separated from the rest of the cell by.... ...The NUCLEAR ENVELOPE is used as a barrier which separates the contents of the nucleus from the cytoplasm‚ all in all keeping the DNA safe and intact. The nuclear envelope regulates the flow of substances into and out of the nucleus. The NUCLEOLUS is an important

Animal Cell Cells are the beginning of everything. Every living thing is composed and made from cells. Cells are the smallest unit of organization that we know of. There are two major categories of cellular organization in eukaryotic cells. Those parts which are “membrane bound”‚ called organelles and those which are not “membrane bound”. Every aspect of the cell is important because each part or organelle’s structure is unique to its function. Non membrane bound organelles‚ are those which provide

Transgenic Animals and Plants What is a transgenic animal/plant? A transgenic animal or plant is one that has a foreign gene (called a "transgene") inserted into its DNA. Transgenic animals and plants are sometimes called "genetically modified organisms" or GMO ’s for short. What is a transgene? A transgene is the foreign gene that has been moved from one organism into a new organism by genetic engineering. For example‚ a bacterial gene that is inserted into a plant ’s DNA would be a

have identical DNA. Sometimes‚ plants are self-pollinated‚ producing seeds and eventually more plants with the same genetic code. Some forests are made entirely of trees originating from one single plant; the original tree spread its roots‚ which later sprouted new trees. When earthworms are cut in half‚ they regenerate the missing parts of their bodies‚ leading to two worms with the same set of genes. However‚ the ability to intentionally create a clone in the animal kingdom by working on the cellular

technology. CELL RELAY Cell relay refers to a method of statistically multiplexing small fixed-length packets‚ called "cells"‚ to transport data between computers or kinds of network equipment. It is an unreliable‚ connection-oriented packet switched data communications protocol. Cell relay transmission rates usually are between 56 kbit/s and several gigabits per second. ATM‚ a particularly popular form of cell relay‚ is most commonly used for home DSL connections‚ which often runs between 128 kbit/s

of change. Carcinogenesis is the development of cancer. Cancer cells are abnormal cells and they have characteristics that can be associated with their ability to grow uncontrollably. Cancer cells are non-specialized‚ and divide uncontrollably. Cancer in situ is a tumor located in its place of origin. Malignant tumors establish new tumor distant from the primary tumors. Cancer cells characteristics distinguish them from normal cells. They have abnormal nuclei with many chromosomal irregularities

DETAILED DIFFERENCES BETWEEN EUKARYOTIC AND PROKARYOTIC CELLS Cells are divided into two categories namely the Prokaryotes and Eukaryotes. These two have varying differences between them. Speaking in simple cell biology words‚ prokaryotes are primitive‚ simple organisms that lack membranous cell organelles. The opposite of this are eukaryotes‚ which are advanced and complex organisms having membrane bound cell organelles. Seemingly simple in structure and markedly different from eukaryote and

Comparing Plant and Animal Cells Hypothesis: I predict I will see the following organelles when observing a plant and animal cell under a microscope: the cell membrane‚ cell wall‚ nucleus‚ and the endoplasmic reticulum. Frog Blood: Analysis: 1. The shape of the frog blood cell was in a circle‚ or oval. The edges were a little irregular‚ but it could still be identified as‚ basically‚ a circular shape. 2. The cells were produced by an animal‚ a frog. 3. The cell wall was not present
