DNALC animations feature stunning visualizations of cellular and molecular processes. Journey inside a cell as you follow proteins in Cell Signals. Zoom along a three-dimensional rendering of 650,000 nucleotides of human chromosome in Chromosome 11 Flyover.
The front (1st page) focuses on the DNA vs. RNA video and the back (2nd page) focuses on the protein synthesis video.
4 lut 2001 · This animation shows how meiosis, the form of cell division unique to egg and sperm production, can give rise to sperm that carry either an X or a Y chromosome. When an egg and sperm combine at fertilization, the embryo regains a diploid number of chromosomes.
31 paź 2023 · To obtain a view of an individual’s karyotype, cytologists photograph the chromosomes and then cut and paste each chromosome into a chart, or karyogram, also known as an ideogram. In a given species, chromosomes can be identified by their number, size, centromere position, and banding pattern.
Each chromosome has a distinct banding pattern, and each band is numbered to help identify a particular region of a chromosome. This method of mapping a gene to a particular band of the chromosome is called cytogenetic mapping. For example, the hemoglobin beta gene (HBB) is found on chromosome 11p15.4.
Genes are located in the chromosomes of cells, with each chromosome pair containing two variants of each of many distinct genes.
Human body cells have 23 pairs of chromosomes, stored in the nucleus; bacteria have one that is stored in the cytoplasm. Sections of the DNA in chromosomes are called genes, which store instructions for inherited features and life processes.
