Chromosome 3 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. People normally have two copies of this chromosome. Chromosome 3 spans more than 198 million base pairs (the building material of DNA ) and represents about 6.5 percent of the total DNA in cells .
In genetics, a locus (pl.: loci) is a specific, fixed position on a chromosome where a particular gene or genetic marker is located. [1] Each chromosome carries many genes, with each gene occupying a different position or locus; in humans, the total number of protein-coding genes in a complete haploid set of 23 chromosomes is estimated at ...
A) Circular bacterial chromosomes contain a cis-acting element, the replicator, that is located at or near replication origins. i) The replicator recruits initiator proteins in a DNA sequence-specific manner, which results in melting of the DNA helix and loading of the replicative helicase onto each of the single DNA strands (ii).

Chromatin is a complex of DNA and protein found in eukaryotic cells. [1] The primary function is to package long DNA molecules into more compact, denser structures. This prevents the strands from becoming tangled and also plays important roles in reinforcing the DNA during cell division , preventing DNA damage , and regulating gene expression ...
C3orf70 also known as Chromosome 3 Open Reading Frame 70, is a 250aa protein in humans that is encoded by the C3orf70 gene. The protein encoded is predicted to be a nuclear protein; however, its exact function is currently unknown. [1] C3orf70 can be identified with known aliases: Chromosome 3 Open Reading Frame 70, AK091454, UPF0524, and ...
There is only one known protein isoform in humans, which is 232 amino acids long and has a predicted molecular weight of 26.9 kDa. [3] It has a predicted isoelectric point of 9. [4] The protein contains a transmembrane domain near the C-terminus. The protein is rich in cysteine and tryptophan and is poor in aspartic acid. [5]
SMC dimers form a V-shaped molecule with two long coiled-coil arms. [19] [20] To make such a unique structure, an SMC protomer is self-folded through anti-parallel coiled-coil interactions, forming a rod-shaped molecule. At one end of the molecule, the N-terminal and C-terminal domains form an ATP-binding domain. The other end is called a hinge ...
