Ribosome

A virus- a complex microscopic organism that possesses the ability to replicate inside the cells of a host. For centuries scientists have debated the topic of whether viruses are living organisms- or not. Viruses have been left in a “gray area”, becoming ignored in the study of evolution by scientists. When not in contact with a host, viruses tend to stray from the characteristics that define life. Characteristics such as the ability to respond to their environment, lack of cells, and the…

City brings her 6-year-old child to see her primary care physician, complaining that her child has seemed “off” for the past month. The child has been extremely fatigued and taking multiple naps during the day that do not seem to refresh her. She is normally a good sleeper at night and recently has begun to have trouble with multiple awakenings. The child has also complained multiple times of frequent headaches throughout the week. She has also been seen to exhibit some confusion while playing…

spindle fibres within the cell. The nucleus contains all DNA makeup and is the centre of each nucleus. Smooth and rough er do the same job they package things to be sent off to different cells. Vesicles contain fluids like water for the cell to use. Ribosomes are used for protein synthesis. Golgi apparatus packages molecules and mitochondria is the powerhouse of the cell creating and storing…

Analyze the anatomical structure of ten different organelles in the cell and their respective functions. Chloroplast: Its main function is photosynthesis trapping energy from the sun and producing sugar from carbon dioxide. Its structure is made up of a double membrane system. They are known as the outer and inner membranes. The inner membrane surrounds the stroma and grana other words known as stacks of thylakoids (NCBI, 2016). Endoplasmic reticulum: Its main function is translation and…

Construction of DNA, RNA, And Protein By Building Models Introduction Nucleic acids are made of nucleotides. When these nucleic acids form sequences they create either DNA or RNA. DNA and RNA are composed of a phosphate, a sugar, and a nitrogen base. The main difference in RNA and DNA is that uracil replaces the base of thymine in RNA. Proteins are essential to maintaining cells by creating hormones and enzymes, and defending the cell. The arrangement of DNA and RNA bases dictates what protein…

causes the cells to commit suicide. These processes decrease the rate of cell division which leads to the decrease of chance an animal might get cancer. 3) Why does a change in gene lead to a change in traits? Use the following words in your response: Ribosome, RNA, DNA, Gene, Amino Acid, Protein A change in gene leads to a change in traits because these genes are copied and passed on to the next generation during reproduction. However, if mutations occur in the DNA, which makes up our gene,…

Summary: All biological molecules contain carbon, hydrogen, and oxygen. A carbohydrate (C,H,O) is a biological molecule consisting of hydrogen , carbon, and oxygen atoms exclusively. They are the building blocks for polysaccharides, larger more complex carbohydrates. An example of a carbohydrate is glucose (the energy source for plants). Carbohydrates are the source of short term energy in organisms. Proteins (C,H,O,N) are made of carbon, hydrogen, oxygen, and nitrogen on a base level. Proteins…

replication of your parents and ancestors genes RNA- is the transcription of dna, ribonucleic acid; guides protein synthesis. Translation- process in which RNA is synthesized from the template DNA. Transcription- process in which RNA attaches to the ribosome and a protein is assembled. Replication- method of DNA replication in which parental strands separate, act as templates, and produce molecules of DNA with one parental DNA strand and one new DNA strand. Mutation- changing of the structure…

Siqi Li May 2015 What topics will students address during the beginning of the school year in Buffalo? During the beginning of the school year in Buffalo, students will study two parts of Living Environment in 7 weeks. The main topic is about the introduction to the course includes the cell which is the foundation of the study of all living things. The key idea 1 in curriculum, living things are both similar and different from each other from nonliving things. The enduring understanding is…

down biological macromolecules via hydrolysis reactions (insertion of a water molecule that breaks intramolecular bonds). Enzymes include; proteases, ribonucleases, deoxyribonucleases – all defined as hydrolases. Such enzymes are synthesised at ribosomes found on endoplasmic reticulum, and are packaged into vesicles that bud from the Trans…
