Chromosome, SEM
Chromosome. Coloured scanning electron micrograph (SEM) of a condensed chromosome showing chromomeres. Chromosomes, which consist of two identical chromatids joined at a centromere

Chromatin beads, artwork
Chromatin beads. Computer artwork of strands of DNA (deoxyribonucleic acid, purple) coiled around histone cores (red) to form the less condensed form of chromatin

Chromatin fibre, artwork
Chromatin fibre. Computer artwork of strands of DNA (deoxyribonucleic acid, green) coiled around histone cores (multicoloured) to form a chromatin fibre

DNA loop, molecular model
DNA loop. Theoretical molecular model of a loop structure for DNA in its chromatin form. DNA (deoxyribonucleic acid) is a helical molecule (here the helix itself forms a circular loop)

Mouse chromatin protein, molecular model
Mouse chromatin protein. Molecular model of the structure of chromatin proteins found in mice. This is similar, but not identical, to the same proteins found in humans

Human chromosome 16, SEM
Human chromosome 16, coloured scanning electron micrograph (SEM). Chromosomes are a packaged form of the genetic material DNA (deoxyribonucleic acid)

Human chromosome 10, SEM
Human chromosome 10, coloured scanning electron micrograph (SEM). Chromosomes are a packaged form of the genetic material DNA (deoxyribonucleic acid)

Chromatin condensation, diagram. This sequence, from right to left, shows the stages by which a long strand of DNA (deoxyribonucleic acid)

Histone structures, diagram. Histone cores are cylindrical structures around which the genetic molecule DNA (deoxyribonucleic acid) is wound with other proteins to form chromatin

Chromatin structure, diagram. The main artwork shows various molecules and a strand of DNA (deoxyribonucleic acid, red) looping round a cylindrical histone core (blue)

DNA packaging, artwork
DNA packaging. Computer artwork showing how DNA (deoxyribonucleic acid) is packaged within cells. Two DNA strands, consisting of a sugar-phosphate backbone attached to nucleotide bases

Animal cell anatomy, artwork
Animal cell anatomy. Artwork showing the internal and external anatomy of an animal cell

Cellular packaging of DNA, artwork
Cellular packaging of DNA. Artwork of a strand of the genetic material DNA (deoxyribonucleic acid) unwound from the nucleus (blue) of a cell (orange, upper right)

Chromosomes, artwork
Chromosomes, computer artwork. Chromosomes are a packaged form of the genetic material DNA (deoxyribonucleic acid). The DNA condenses into chromosomes during cell replication for ease of division

Small lymphocyte, TEM
Small lymphocyte. Coloured transmission electron micrograph (TEM) showing the large central nucleus (brown) of a small lymphocyte (white blood cell)

White blood cell, TEM
White blood cell. Coloured transmission electron micrograph (TEM) of an eosinophil (a type of white blood cell), part of the bodys immune system

Cell organelles, SEM
Cell organelles. Coloured scanning electron micrograph (SEM) of a section through a cell from a kidney proximal tubule. The cell nucleus (partially seen at top left)

Cell nucleus, SEM

X and Y chromosomes, artwork
X and Y chromosomes. Computer artwork of X (red) and Y (blue) chromosomes. Chromosomes are a packaged form of the genetic material DNA (deoxyribonucleic acid)

Chromosomes and DNA, artwork
Chromosomes and DNA. Computer artwork of X (pink) and Y (green) chromosomes with an autoradiogram in the background. Chromosomes are a packaged form of DNA (deoxyribonucleic acid)

Chromosome, artwork
Chromosome, computer artwork. Chromosomes are a packaged form of the genetic material DNA (deoxyribonucleic acid, blue strands)

Cell nuclei with chromatin

Chromatin, the intricate web of genetic material within our cells, holds the key to understanding life's blueprint. At its core lies the nucleosome molecule, a fundamental building block consisting of DNA wrapped around proteins. In a stunning molecular model, we witness the elegant dance between these two entities. Peering through an electron microscope, we uncover plasma cells with their chromatin in full view. The TEM image reveals the intricate organization and compactness of this vital substance within these specialized immune system warriors. Moving on to human chromosomes captured by SEM, we are mesmerized by their striking beauty. These thread-like structures hold our entire genetic code and play a crucial role in inheritance and development. Shifting gears to plant cells, a conceptual image showcases not only chromatin but also other essential components that make up these green powerhouses, and is here where photosynthesis takes place and life flourishes against all odds. Delving deeper into animal cell territory under microscopic scrutiny once again unveils chromatin's presence. Its delicate strands intertwine amidst various organelles like mitochondria and ribosomes – orchestrating cellular functions critical for survival. Comparing plant and animal cell anatomy side by side brings forth fascinating insights into evolutionary divergence. With labels highlighting distinct features such as chloroplasts or centrioles, it becomes evident how nature has tailored each organism's chromatin architecture to suit its unique needs. In multiple microscopic views of animal cells, we witness firsthand the sheer complexity hidden beneath our skin's surface. Chromatin intricately woven alongside countless other cellular components reminds us that life is indeed an extraordinary tapestry waiting to be unraveled. As scientists continue unraveling chromatin's mysteries, one thing remains certain: this enigmatic entity holds profound significance in shaping who we are as living beings. From nucleosomes to chromosomes across diverse organisms' cells – every glimpse deepens our appreciation for this remarkable phenomenon known as chromatin.
