normal chromosomes 예문

• So why aren't the ends of normal chromosomes equally alarming to the cell?
• Unfortunately, genetic abnormalities could still exist despite having normal chromosomes.
• But that does not take place in normal chromosomes.
• PGH differs from common PGD methods such as translocation versus those carrying the homologous normal chromosomes.
• There is something special about the ends of normal chromosomes that protects them from degradation and subsequent fusion.
• However, dynactin p27 / p25 are required for normal chromosome alignment, kinetochore-microtubule interaction, and proper timing of anaphase onset.
• Theoretically, X-inactivation should eliminate the differences in gene dosage between affected individuals and individuals with a normal chromosome complement.
• The new discovery provides the answer : Normal chromosomes have no ends, just the unbroken continuum of a circle.
• Cytological studies have shown some 27 species of Crinum to be diploid with a normal chromosome count of 2n = 22.
• As chromosomes occur in pairs, the affected individual usually has one normal chromosome and the other replaced by a ring chromosome.
• Chromosomes that have PCS will have their centromeres separate during metaphase rather than anaphase ( one phase earlier than normal chromosomes ).
• Steck's approach was to add little chunks of normal chromosome 10 to brain cancer cells to see which one of them would restrain growth.
• The loops provide the answer that no one had divined : Normal chromosomes have no ends, only the perfect topological continuum of a circle.
• Common fragile sites are considered part of normal chromosome structure and are present in all ( or nearly all ) individuals in a population.
• In at least one case, this euploid zygote has been traced through development to birth as a healthy child with a normal chromosome count.
• The evolutionary origin of supernumerary chromosomes is obscure, but presumably they must have been derived from heterochromatic segments of normal chromosomes in the remote past.
• In most individuals with ring chromosome 20 syndrome, a certain percentage have two normal chromosome 20s and the remainder have one normal and one ring 20 chromosome.
• Although many children with holoprosencephaly have normal chromosomes, specific chromosomal abnormalities have been identified in some patients ( trisomy of chromosome 13, also known as Patau syndrome ).
• The eggs have normal chromosomes, which led him to suspect that the problem is with the cytoplasm, which contains proteins that direct the development of embryos just after fertilization.
• Tsix is a negative regulator of Xist; X chromosomes lacking Tsix expression ( and thus having high levels of Xist transcription ) are inactivated much more frequently than normal chromosomes.
