Molecules of cell nucleus in the interphase. Nucleolus (the granular structure), DNA being transcripted to mRNA (pink) by the RNA polymerase (green), and several enzymes: the endonuclease (violet), the DNA ligase (yellow) and the DNA topoisomerase (magenta)

Ring formation of thumbs ups like logos scattered into groups, symbolizing varied demographic positive opinions, crystal glass renders.

Nucleosome, molecular model. 3D illustration. The nucleosome consists of a DNA double helix wrapped around a core of histone proteins.

3D cartoon and Gaussian surface models, chain id color scheme, PDB 7t3a, white background

$Viral Infection Monkeypox Virus - 3d rendered image. Abstract biomedical illustration. \nAntibody, Antigen, Vaccine technology concept.$

Covid-19 coronavirus binding to human cell, conceptual computer illustration. SARS-CoV-2 coronavirus (previously 2019-nCoV) binding to an ACE2 receptor on a human cell (not to scale). SARS-CoV-2 causes the respiratory infection Covid-19, which can lead to fatal pneumonia. ACE2 (angiotensin-converting enzyme 2) is a membrane-bound aminopeptidase, the key host receptor for the spike glycoprotein of SARS-CoV-2 which serves as initial step in the development of coronavirus infection on a cellular level and a potential target for treatment strategy.

Evolution of nanotechnology and self-proliferation of therapeutic agents

$The Raf/MEK/ERK (MAPK) propagates growth signals in the cell. Misregulation can lead to cancer.\nThe red dots on the active EGFR are phosphorylated tyrosines. PDB entries: 1egf, 1nql, 1m17, 2jwa, 3njp, 2gs6, 1gri, 1xd2, 3ksy, 5p21, 6xi7, 6q0j, 2y4i,$

$The three-dimensional structure of proteins is represented in a variety of conformations. This image is based on the ribbon structure of a protein. It is suitable for biology notebooks and book covers.\nThis image has not been created by AI.$

Ribonucleic acid strands consisting of nucleotides important for protein bio-synthesis - 3d illustration

Different germs in the human intestines called microbiome,Bacteria Lactobacillus in human intestine,Beneficial healthy intestinal bacterium microflora,Gut bacteria

MicroRNAs are transcribed from DNA by RNA polymerase 3D rendering

Endosomes - 3d rendered image of Endosomes are membrane-bound organelles. They are parts of endocytic membrane transport pathway. Endomembrane system in cells. Bilayer Lipid Membrane. Abstract medical illustration. Microscopic view. Microbiologic research concept.

The model shows the 30S ribosome RNA (blue), three tRNA (top), and ribosomal proteins. 3D Gaussian surface model, white background

mRNA (multicoloured strand) is decoded in a ribosome to produce an aminoacid chain, that folds into a protein (red). tRNA (dark violet) molecules carry single aminoacids that are incoporated into the growing chain.

$Liquid-liquid phase separation (LLPS), which is the separation between liquids present in the cell. Organelle without membrane．Droplets usually have an important function, but can also cause disease if they lose their function.\nThis image was not created by AI.$

Bacteriophage Virus Cycle Phage replicating inside a pathogen as a virus with nucleic acid infecting bacteria as a virology symbol as a pathogen that attacks bacterial infections as a bacteriophages.

A model of a nucleosome. Isolated on black.

Liposomes are used to efficiently deliver cargo molecules such as siRNA, mRNA, or RNA into cells in vitro and in vivo 3d rendered

3D cartoon and Gaussian surface models. PDB 3kqg, chain id color scheme, white background.

Epidermal growth factor (EGF) activates the EGF receptor (EGFR), that builds a heterodimer with HER3. The signal transduction continues through GRB2/SOS, Ras, Raf/MEK and ERK, that will activate many processes in the cell. Dysregulation is linked to cancer progression

Propagation of the virus in the human body. How coronavirus attacks cells. If the virus finds a compatible receptor allow covid-19 to replicate itself. Section of the cell and SARS-CoV-2. 3d render

$Phospholipid bilayer membrane structures that make up living cells and their contents. This is an image of membrane proteins in the membrane.\nThis image, which looks like a plastic model, evokes biology and biochemistry. It can be used as a cover for magazines, textbooks and presentation materials.\nThis image was not created by AI.$

The translation of a nucleotide (DNA or RNA) sequence to a protein sequence 3d rendering

$Viral Infection Monkeypox Virus - 3d rendered image. Medical illustration of mpox virus structure and skin lesions, highlighting key aspects of this global health concern. Abstract biomedical illustration. \nAntibody, Antigen, Vaccine technology concept.$
