Eukaryotic cells are typically 10-100 µm in diameter which are larger than prokaryotic cells. Eukaryotic cells (eukaryotic is from the Greek eu, true, and karyon, kernel, here referring to the nucleus)… Read more »
Mitochondrion (plural, mitochondria) is found abundantly in eukaryotic cells. It is about 1 to 10μm long. Eukaryotic cells have one or more mitochondria. The number of mitochondria is directly proportionally… Read more »
Animal cells have many organelles such as nucleus, endoplasmic reticulum, Golgi body, vesicles and mitochondria. Animal cells have non-membranous structure such as ribosomes and cytoskeleton. Some animal cells have flagella… Read more »
Golgi bodies are flattened membranous sacs and look like pancake. Golgi bodies play an central role in manufacturing, warehousing, sorting and shipping. It contains enzymes. Products from endoplasmic reticulum are… Read more »
Endoplasmic reticulum is membrane system continuous from nuclear envelope and extends to cytoplasm. The word endoplasmic means “within the cytoplasm,” and reticulum is Latin for “little net”. In many eukaryotic… Read more »
Eukaryotic cells protect their DNA in the nucleus. It contains most the genes of eukaryotic cells except some are located in mitochondria and chloroplast. It is about 5µm in diameter…. Read more »
Nucleic acid Nucleic acid is polynucleotide. Nucleotide is the building block of nucleic acid. There are two types of nucleic acids: DNA and RNA (ribonucleic acid). Nucleotide Nucleotide consists of… Read more »
Mitosis is a process where the cell divides and the daughter cells have the same number of chromosomes with the parent cell. Mitosis occur in somatic cells. Mitosis plays an… Read more »
Mutation is an unpredictable, random and spontaneously changes in genetic material. Different alleles of a gene contain slightly different sequence of base. It is caused by several environmental factors: Ionizing radiation… Read more »
