Biology - Introduction to Advanced Learning Path

The science sector continues to grow worldwide, and with this growth is an increasing demand for professionals in the science sector. Biology is one of the three main science subjects, and so it is vital that those wishing to work in the science sector have an understanding of its guiding principles. The Alison learning path in biology focuses on the main principles which govern biological processes and will help you to build a solid knowledge base on the subject. This learning path will be of interest to you if you wish to work in any science-related field; such as pharmaceuticals, the health system, and the food industry. The Alison biology learning path is a list of courses which will help you to further understand the basics of the biological field, and build on these basics with more advanced knowledge. You will learn about key elements of biology, such as cells, genes, and DNA. For example, you will be able to discuss the composition of cells and explain their division. You will also learn about the effects which DNA and genetics have upon the body, and how they impact hereditary traits.

    In this physiology course you will be introduced to the main topics in cell physiology such as the major components of a typical animal cell. You will learn about the mechanisms behind cell growth and multiplication, about the movement of substances into and out of cells, how energy is processed within the cell, and how and why cells maintain an electrical charge across their membranes called membrane potentials.

    This cell physiology course will be of great interest to all healthcare professionals who would like to learn more about the structure and function of cells, and to all students of biology and medicine who would like a greater knowledge and understanding of the mechanisms and processes involved in cell physiology.

  3. Biology - Genes and Gene Technology

    This course was sourced from OpenLearn under the Creative Commons licence conditions BY NC SA. The adapted version of the course on Alison.com is also published under the Creative Commons licence conditions BY NC SA.

    It is over sixty years since the structure of DNA was first discovered by Watson and Crick. Since then work in genetics and gene technology has expanded to the point where the entire human genome has been sequenced, and there is now hope of being able to cure diseases using gene therapy. There is also on-going work in the area of modifying plant DNA to produce pest-resistant crops that give bigger harvests for more food. Today, people need a thorough knowledge and understanding of genetics and gene therapy so that they can make up their own minds as to the potential benefits and drawbacks of what this field of science can offer us.

    In this free online course you will discover what genes do and explore and come to understand reference terms such as meiosis and mitosis. The course also covers evolutionary aspects of DNA and the genome. You will also learn about gene technology which includes gene testing, gene therapy and the controversial area of genetic modification in plants.

    This course will be of great interest to professionals working in the areas of biology, medicine and development, to learners who would like a career in the areas of genetics and gene technology, and to anyone interested in understanding the basic area of science that underpins all living existence.

  4. Biology - Cell Division

    Cell division and replication are fundamental biological processes that occur in all organisms.

    This course about cell division will explain the complex processes of cell division in detail. You will learn about mitosis and meiosis and the phases that occur in each of these processes. You will learn that in the early stages of development embryonic cells can generate all cell types in the body. You will also look at how cells divide and replicate allowing us grow and repair body tissues, and if damage occurs, how some cells can replicate faster than surrounding cells to form tumours.

    This course will be of great interest to all students who wish to pursue a career in the sciences, medicine, pharmacy, nursing, biology or biodiversity or the individual learner who simply wants to learn more about mitosis, meiosis and their role in cell division and replication.

  5. Biology - Evolution, Natural Selection and DNA

    Evolution is a process of gradual change that takes place over many generations. During this time, species of animals, plants, or insects slowly change some of their physical characteristics. This course will start with an introduction to evolution and natural selection. You will learn about Darwin's idea of evolution by natural selection which involves variation, differential reproduction, and heredity. You will also look into the natural selection and the owl butterfly to give you a better understanding of the concept.

    DNA, or deoxyribonucleic acid, is the basic unit of heredity or the hereditary material in humans and almost all other organisms. Nearly every cell in a person's body has the same DNA. This course will discuss how the DNA codes all of our genetic information. You will also study the variation in a species and look into chromosomes, chromatids, and chromatin. You will learn that chromosomes are single-stranded groupings of condensed chromatin, and a chromatid is one-half of two identical copies of a replicated chromosome.

    In evolution, the success of a species can depend on changes to just one allele on one gene in one chromosome. By the end of this course, you will learn about the naturally occurring variation within species and how mutations and reproduction continue this process. You will also learn how DNA copies itself and turns into the proteins that make up all living organisms. Check out this course and learn more about how and why there is such diversity among plants and animals today.

  6. Biology - Heredity

    Gregor Mendel is the founder of the science of genetics and is known as the father of genetics. He identified many of the rules of heredity which determine how traits are passed through generations of living things, and that traits could skip a generation. This course will introduce you to Gregor Mendel and his works on heredity. You will also explore every different combination of all the genes using the Punnett square.

    The Hardy–Weinberg Equilibrium (HWE) states that allele and genotype frequencies in a population will not change from generation to generation where there is an absence of other evolutionary influences or disturbing factors. This course will discuss the Hardy-Weinberg equilibrium and give you examples to understand the principle better. You will also study sex-linked traits, which is an important category of genetic linkage that has to do with the X and Y sex chromosomes.

    Heredity is the genetic transmission of characteristics from parent to offspring. By the end of this course, you will have learned how some of these characteristics can have a physical manifestation like hair color or color blindness, why some traits are passed on while others skip generations, and why some traits form part of our physical makeup while others are carried but never physically expressed. So, check out the course today and start learning all this and more!
