which a cell duplicates the chromosomes in its cell nucleus in order to generate two identical daughter nuclei. • Interphase: This particular stage is divided into three phases‚ G1 (first gap)‚ S (synthesis)‚ and G2 (second gap). During all three phases‚ the cell grows by producing proteins and other organelles within the cytoplasm. However‚ chromosomes are replicated only during the S phase. In all‚ a cell grows (G1)‚ continues to grow as it duplicates its chromosomes (S)‚ grows more and prepares

What do you get when you mix a cow and a buffalo? A beefalo. What do you get when you mix a zebra and a horse? A zorse‚ of course. These may sound like silly jokes told by a preschooler‚ but these animals do exist and there are many other combinations of animals. A hybrid animal is the offspring of two different species or populations (Wikipedia). There are already hybrid animals in existence that occur in nature and some that are being created by science. In this paper‚ some examples‚ characteristics

Question/Problem Which phase of cell division / mitosis is seen most often in whitefish blastula? Introduction Cell division is the process of a parent cell dividing into two daughter cells. Mitosis is a type of cell division. In mitosis a parent cells chromosomes are copied and separated into two cells with different nucleuses but same DNA. There are steps or phases that take place that make the cell divide. The first phase is called Interphase. In interphase there are sub groups such as gap 1‚ 2 and synthesis

Determining the Crossover Frequency in Sordaria fimicola Introduction Meiosis is an important part of the life cycle that gives rise to the genetic variation in offsprings. Meiosis in fungi differs from those in plants and animals. Fungi are composed of hyphae‚ which are tubules that make up the frame. These hyphae together form a clump or a mat that is the mycelium (Campbell‚ 637). The hyphae are key to fungus reproduction. Typically fungi produce large amounts of spores through either sexual

During the G1 phase‚ the cell increases in mass except for the chromosomes‚ which stay the same. Protein synthesis is also occurring during this phase. If a cell doesn’t divide further‚ it remains in the G1 phase. Next is the S phase‚ in which the mass of the cell continues to increase‚ and DNA is duplicated‚ and then the chromosomes divide. During the G2 phase of Interphase‚ the cell becomes double its mass at birth‚ the chromosomes begin to shorten and coil‚ and the centrioles appear‚ the cell

other ways. Color blindness can also happen if physical or chemical damage is done to the eye‚ the optic nerve‚ or parts of the brain. The gene that produces photopigment is on the X chromosome. The X chromosome is sex-linked which is why color blindness usually is more dominant in males. Males have only one X chromosome. If this gene is

Each chromosome is made up of DNA (deoxyribonucleic acid) and protein. DNA contains tiny segments called genes that we inherit from our parents.
