A chromosome goes missing in anaphase
5766
Anaphase is the critical step during mitosis when sister chromosomes are disjoined and directed to opposite spindle poles, ensuring equal distribution of the genome during cell division. View Media
Alternative splicing
2552
Arranging exons in different patterns, called alternative splicing, enables cells to make different proteins from a single gene. Crabtree + Company View Media
CRISPR Illustration Frame 2

This illustration shows, in simplified terms, how the CRISPR-Cas9 system can be used as a gene-editing tool. National Institute of General Medical Sciences. View Media
Arabidopsis leaf injected with a pathogen
2780
This is a magnified view of an Arabidopsis thaliana leaf eight days after being infected with the pathogen Hyaloperonospora arabidopsidis, which is closely related to crop pathogens that Jeff Dangl, University of North Carolina, Chapel Hill View Media
Life of an AIDS virus (with labels)
2514
HIV is a retrovirus, a type of virus that carries its genetic material not as DNA but as RNA. Crabtree + Company View Media
Precise development in the fruit fly embryo
2593
This 2-hour-old fly embryo already has a blueprint for its formation, and the process for following it is so precise that the difference of just a few key molecules can change the plans. Thomas Gregor, Princeton University View Media
Planarian stem cell colony
3306
Planarians are freshwater flatworms that have powerful abilities to regenerate their bodies, which would seem to make them natural model organisms in which to study stem cells. Peter Reddien, Whitehead Institute View Media
Epigenetic code
2562
The "epigenetic code" controls gene activity with chemical tags that mark DNA (purple diamonds) and the "tails" of histone proteins (purple triangles). Crabtree + Company View Media
Nucleotides make up DNA
2541
DNA consists of two long, twisted chains made up of nucleotides. Each nucleotide contains one base, one phosphate molecule, and the sugar molecule deoxyribose. Crabtree + Company View Media
Life of an AIDS virus (with labels and stages)
2515
HIV is a retrovirus, a type of virus that carries its genetic material not as DNA but as RNA. Crabtree + Company View Media

Chromosomes before crossing over
1315
Duplicated pair of chromosomes lined up and ready to cross over. Judith Stoffer View Media
Microscopy image of bird-and-flower DNA origami
3690
An atomic force microscopy image shows DNA folded into an intricate, computer-designed structure. Hao Yan, Arizona State University View Media
Induced stem cells from adult skin 04
2606
The human skin cells pictured contain genetic modifications that make them pluripotent, essentially equivalent to embryonic stem cells. James Thomson, University of Wisconsin-Madison View Media
Histone deacetylases
7001
The human genome contains much of the information needed for every cell in the body to function. However, different types of cells often need different types of information. Amy Wu and Christine Zardecki, RCSB Protein Data Bank. View Media
Alternative splicing (with labels)
2553
Arranging exons in different patterns, called alternative splicing, enables cells to make different proteins from a single gene. Featured in The New Genetics. Crabtree + Company View Media
Meiosis illustration
2545
Meiosis is the process whereby a cell reduces its chromosomes from diploid to haploid in creating eggs or sperm. Crabtree + Company View Media
Central dogma, illustrated (with labels and numbers for stages)
2549
DNA encodes RNA, which encodes protein. DNA is transcribed to make messenger RNA (mRNA). The mRNA sequence (dark red strand) is complementary to the DNA sequence (blue strand). Crabtree + Company View Media
Assembly of the HIV capsid
5729
The HIV capsid is a pear-shaped structure that is made of proteins the virus needs to mature and become infective. John Grime and Gregory Voth, The University of Chicago View Media
CRISPR Illustration Frame 1

This illustration shows, in simplified terms, how the CRISPR-Cas9 system can be used as a gene-editing tool. This is the first frame in a series of four. National Institute of General Medical Sciences. View Media
Lily mitosis 13
1019
A light microscope image of cells from the endosperm of an African globe lily (Scadoxus katherinae). This is one frame of a time-lapse sequence that shows cell division in action. Andrew S. Bajer, University of Oregon, Eugene View Media
Nucleotides make up DNA (with labels)
2542
DNA consists of two long, twisted chains made up of nucleotides. Each nucleotide contains one base, one phosphate molecule, and the sugar molecule deoxyribose. Crabtree + Company View Media
Genetic mosaicism in fruit flies
6983
Fat tissue from the abdomen of a genetically mosaic adult fruit fly. Genetic mosaicism means that the fly has cells with different genotypes even though it formed from a single zygote. Akhila Rajan, Fred Hutchinson Cancer Center View Media
