On the template strand, polymerase will synthesize in the opposite direction from the replication fork. Once the template becomes discontinuous, it will create an Okazaki fragment. Defects in the maturation of Okazaki fragments can potentially cause strands in the DNA to break and cause different forms of chromosome abnormality.
This process is known as Okazaki fragment maturation and can be handled in two ways: one mechanism processes short flaps, while the other deals with long flaps. [94] DNA polymerase δ is able to displace up to 2 to 3 nucleotides of DNA or RNA ahead of its polymerization, generating a short "flap" substrate for Fen1 , which can remove ...
The Maturational Theory of child development was introduced in 1925 [1] by Dr. Arnold Gesell, an American educator, pediatrician and clinical psychologist whose studies focused on "the course, the pattern and the rate of maturational growth in normal and exceptional children"(Gesell 1928). [2]

[7] [10] Based on his theory, he published a series of summaries of child development sequences, called the Gesell Developmental Schedules. The Gesell Institute of Human Development, named after him, was started by his colleagues from the Clinic of Child Development, Frances Ilg and Louise Bates Ames in 1950, after Gesell retired from the ...

Reiji Okazaki (岡崎 令治, Okazaki Reiji, October 8, 1930 – August 1, 1975) was a pioneer Japanese molecular biologist, known for his research on DNA replication and especially for describing the role of Okazaki fragments along with his wife Tsuneko. Okazaki was born in Hiroshima, Japan.
