Lesson 1: Natural Selection
Evolution proposes that species change over time, give rise to new spices, and share a common ancestor. Natural selection proposes that because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations. In this video, you will learn in detail about evolution, natural selection, history of evolution and natural selection, Lamarck’s theory of inheritance of acquired characteristics.
06:57

07:33
Lesson 3: Evidence of Evolution
In this video, we will talk about evidence of evolution. In science, everything needs evidence to be proposed as a theory and in this case, evolution has multiple forms of evidence which include comparative anatomy, comparative embryology, molecular biology, biogeography, and fossils.
03:56
Lesson 1: Chloroplast
Chloroplast is found in plant cells. The chloroplast in a plant cell is the kidney-bean-shaped membrane. You need to know the different parts of a chloroplast because they have different functions and photosynthesis. Chloroplasts have two membranes. In this video, I am going to show you the parts of a chloroplast and their functions.
01:43
Lesson 2: Light Dependent Reaction
Photosynthesis consists of two light reactions- dependent and independent. In this video, we will talk about the first reaction of photosynthesis which is the light-dependent reaction which occurs in the stroma of the chloroplast. You will learn about photosynthesis, steps of photosynthesis, input and output of light-dependent reaction.
02:46
Lesson 3: Light Independent Reaction
Photosynthesis consists of two light reactions- dependent and independent. In this video, we will be talking about the second reaction of photosynthesis which is the light-independent reaction. Light-independent reaction, also known as the Calvin cycle, is not dependent on light and can occur in the dark. You will learn about photosynthesis, steps of photosynthesis, input and output of light-independent reaction.
02:48
Lesson 1: The Mitochondria
In this video, we will talk about the membrane-bound organelle, otherwise known as the mitochondria, that generate most of the chemical energy needed to power the cell’s biochemical reactions. In real life, the membrane-bound organelles are colorless. You will learn about the parts of mitochondria.
01:25
Lesson 2: Glycolysis
Glycolysis is the first step of cellular respiration and it occurs in the cytoplasm. The chemical equation for glycolysis is the opposite of the chemical equation of photosynthesis. In this video, you will learn about cellular respiration, steps of cellular respiration, input, output, and net output of glycolysis.
04:07
Lesson 3: Kreb's Cycle
Kreb’s cycle, also known as citric acid cycle is the second step of cellular respiration and it occurs in the matrix. The citric acid cycle occurs in two steps which are the Acetyl-CoA formation and Kreb’s cycle. In this video, you will learn about cellular respiration, steps of cellular respiration, input and output of Acetyl-CoA formation and Kreb’s cycle.
02:54
Lesson 4: Electron Transport Chain
Electron Transport Chain (ETC) is the third and final step of cellular respiration and it occurs in the inner membrane. In this video, you will learn about cellular respiration, steps of cellular respiration, input and output of Electron Transport Chain.
04:42
Lesson 1: Mitosis
Mitosis is a sexual reproduction that produces body cells (somatic cells). In this video, you will learn about mitosis, the cell cycle which includes interphase and cell division, and phases of mitosis in cell division.
05:21
Lesson 2: Meiosis
Meiosis occurs in sexual reproduction and produces sex cells (gametes). In the cell cycle, there are two meiosis- meiosis I and meiosis II. In this video, you will learn about meiosis, the cell cycle, meiosis I and meiosis II, increasing diversity II: independent assortment.
06:38
Lesson 1: Replication
The process of DNA creating DNA is replication. Replication is the first step of the central dogma. Replication occurs in the nucleus. In this video, you will learn about the central dogma, steps of the central dogma, the couples of enzymes that you need to know for replication.
03:10

Pre-MRNA processing consists of three steps- 5’methylguanosine cap, 3’ poly-A tail, Intron-exon splicing. Pre-MRNA occurs in the nucleus. In this video, you will learn about the central dogma, steps of the central dogma, and the three necessary steps for Pre-mRNA to turn into mRNA and be able to exit the nucleus that has been degraded in the process.
02:12
Lesson 4: How to Read a Codon Chart
A codon chart can be used to translate a genetic code into a sequence of amino acids. A codon contains three bases- first base, second base, and third. In this video, I will show you step-by-step how to read a table and circular codon chart.
01:30

Lesson 1: Mendelian Genetics
In this video, you will learn about chromosomes, gene, allele, dominant, recessive, genotype, phenotype, homozygous dominant, homozygous recessive, and heterozygous. You will also learn about the 3 Mendel’s laws- Law of dominance, Law of segregation, and Law of Independent assortment.
05:25
Lesson 2: How to Draw a Punnett Square
A Punnett square is a graphical representation of the possible genotypes of an offspring arising from a particular cross or breeding event. You will learn how to draw a Punnett square with examples.
05:51

In this video, we will talk about the differences between incomplete dominant and codominance. We will also look at examples of incomplete dominance and codominance.
06:17
Lesson 4: Blood Typing
They are 4 blood types- A, B, AB, and O. Your blood group is determined by the genes you inherit from your parents. Each group can be either RhD positive or RhD negative, which means in total, there are 8 blood groups. In this video, you will learn about the types of blood group with examples.
03:31
Lesson 5 : Sex-Linked Inheritance & Colorblindness
Males have an X chromosome and a Y chromosome, and females have two X chromosomes. In this video, we will talk about a sex-linked trait called color blindness. Color blindness, also known as color vision deficiency, is the decreased ability to see color or differences in color.
