Serial homology is a special type of homology, defined by Owen as "representative or repetitive relation in the segments of the same organism." [ 1 ] Ernst Haeckel preferred the term "homotypy" for the same phenomenon.
Homologous recombination is the proposed mechanism whereby the DNA virus human herpesvirus-6 integrates into human telomeres. [ 92 ] When two or more viruses, each containing lethal genomic damage, infect the same host cell, the virus genomes can often pair with each other and undergo homologous recombinational repair to produce viable progeny.
Humans is a science fiction television series that debuted on 14 June 2015 on Channel 4.Written by the British team Sam Vincent and Jonathan Brackley, based on the Swedish science fiction drama Real Humans, the series explores the themes of artificial intelligence and robotics, focusing on the social, cultural, and psychological impact of the invention of anthropomorphic robots called "synths".
In biology, homology is similarity in anatomical structures or genes between organisms of different taxa due to shared ancestry, regardless of current functional differences. Evolutionary biology explains homologous structures as retained heredity from a common ancestor after having been subjected to adaptive modifications for different ...
Whereas ordinary homology is seen in the pattern of structures such as limb bones of mammals that are evidently related, deep homology can apply to groups of animals that have quite dissimilar anatomy: vertebrates (with endoskeletons made of bone and cartilage) and arthropods (with exoskeletons made of chitin) nevertheless have limbs that are constructed using similar recipes or "algorithms".
Dr. Molly Brinkmann, a veterinarian from Tennessee, made the most relatable TikTok video about how different dog breeds (and even a few cats) greet their humans, and pet owners from across the ...
Sequence homology is the biological homology between DNA, RNA, or protein sequences, defined in terms of shared ancestry in the evolutionary history of life. Two segments of DNA can have shared ancestry because of three phenomena: either a speciation event (orthologs), or a duplication event (paralogs), or else a horizontal (or lateral) gene ...
Homology-directed repair (HDR) is a mechanism in cells to repair double-strand DNA lesions. [1] The most common form of HDR is homologous recombination . The HDR mechanism can only be used by the cell when there is a homologous piece of DNA present in the nucleus , mostly in G2 and S phase of the cell cycle .
