Hox gene is an example of a homeobox gene. The homeobox sequence codes for a 60 amino acid protein domain known as the homeodomain. The main role of homeodomain is to act as a switch that controls gene transcription.
(Histone modification hassome attributes of an epigenetic process, but the issue ofheritability has yet to be resolved.) This review concernsDNA methylation, focusing on the generation, inheri-tance, and biological significance of genomic methyl-ation patterns in the development of mammals.
The method of replication is semi-conservative; this means that in the two daughter helices one strand of each is comprised of parental DNA (from the original helix), and the other is comprised of newly synthesised DNA. Synthesis occurs at the replication fork, our focus in this article.Replication is a complex process, involving many, many different enzymes-such as DNA polymerase-which have frustratingly similar names to enzymes in other processes.he method of replication is semi-conservative; this means that in the two daughter helices one strand of each is comprised of parental DNA (from the original helix), and the other is comprised of newly synthesised DNA.
