Codominance is the type of interaction in which both the alleles of a gene are observed in a phenotype. Coat color in some cows is an example of codominance. A cow in which one allele for red coat color is inherited from one parent, and one allele for white coat color is inherited from another parent, will have both red and white hair.

We all know of DNA as the genetic material of our cells and the process of DNA replication is SO important. Let's find out why!

DNA Replication

Molecular Biology

Cells make up the basic level of our body and other living things. They are the fundamental unit of life. If so, is there is a difference between us and other single-cell organisms such as bacteria? This simulation is all about eukaryotic cells that are the building blocks of our body!

Eukaryotic Cell

Photosynthesis is a process by which plants make their own food. They require carbon dioxide from air, and water from the soil to make their food in the form of sugar. This process occurs in the presence of sunlight, and chlorophyll present in the plant’s leaf. The whole process takes place in the chloroplasts of the mesophyll cells of the leaf, and gets completed in two steps: capturing light energy and making sugars.

RNA Transcription

RNA translation is the process by which cells make proteins. In translation, messenger RNA (mRNA) carries genetic information from DNA to ribosomes, where transfer RNA (tRNA) reads the code and assembles amino acids into a specific protein. This process is essential for cell growth and function.

__Purine Nucleobases__

Purine nucleobases adenine (A) and guanine (G) are one of the two nitrogenous bases found in DNA and RNA. Adenine forms hydrogen bonds with complementary pyrimidine bases (thymine in DNA and uracil in RNA) to form base pairs that make up the double-helix DNA and single-stranded RNA structures.

__Hydrogen__

Hydrogen bonds play a critical role in the process of DNA replication. During DNA replication, the double-stranded DNA molecule must be separated into two single strands. Hydrogen bonds between the complementary base pairs of the two strands must be broken to allow the separation of the strands.

__Nitrogen__

Nitrogen atoms play a crucial role in DNA replication by forming the base pairs that make up the genetic code. The nitrogenous bases, adenine (A), thymine (T), guanine (G), and cytosine (C), are the building blocks of DNA.

__Carbon__

Carbon atoms play an essential role in DNA replication by providing the backbone of the DNA molecule.

__Chemical Bonds__

Chemical bonds are the attractive forces between atoms. These bonds form when atoms share or exchange electrons to achieve a stable electron configuration. The bond formed depends on the electronegativity of the atoms involved. Chemical bonds are crucial in determining the properties and behavior of molecules and compounds.

Our entire genome is coded basically by just four building blocks: guanine, adenine, thymine, and cytosine! Here's a quick look at the nucleobase adenine!

__African Lungfish__

Lungfish is a type of fish that belongs to the class Sarcopterygii, also known as lobe-finned fish. They have fleshy, lobed fins that resemble limbs. Lungfish can breathe air through their lungs, allowing them to survive in oxygen-poor water and burrow in mud during periods of drought. Lungfish can also extract oxygen from water using their gills.
