Also, whereas bacterial chromosomes are circular, eukaryotic chromosomes are linear. During circular DNA replication, the excised primer is readily replaced by nucleotides, leaving no gap in the ...
These new combinations result from the exchange of DNA between paired chromosomes. Such exchange means that the gametes produced through meiosis exhibit an amazing range of genetic variation.
DNA comprises the genes and chromosomes that govern the development of an individual organism. Coiled inside the nucleus of the cell, DNA stores all the information needed in reproducing that ...
Your chromosomes are how your cells store your DNA. They also help ensure the accurate copying of DNA during cell replication. This DNA is grouped into segments called genes. Your genes determine ...
We have also argued that unlinking of the sister chromosomes during DNA replication is aided by removal of pre-catenanes that are forming directly at or just behind the replication fork (Fig. 8) and ...
We are interested in the mechanism of chromosome replication, a process that is highly conserved across eukaryotes and that involves the duplication of both the chromosomal DNA and its associated ...
The nucleus of each human body cell contains 46 chromosomes. Each chromosome contains about 1000 genes. There is enough DNA in all the cells in a human body to stretch to the sun and back again ...
This important study presents compelling observational data supporting a role for transcription and polysome accumulation in the separation of newly replicated bacterial chromosomes. The study is ...
Instead of the linear chromosomes found in mammals, the team crafted a circular chromosome, which is compatible with DNA replication in yeast. They then assembled the HAC inside budding yeast. By ...
The Homo sapiens genome today contains a little bit of Neanderthal DNA. These genetic traces come from almost every part of ...
How cells respond to mitochondrial DNA (mtDNA) damage is not fully understood. This study uncovers a mechanism of mtDNA ...
In addition to shelterin, telomeric DNA is also wrapped around histone octamers in a closed, heterochromatic state that compacts telomeric DNA and represses transcription at the chromosome end ... in ...
