Duplications of 12p - Unique Understanding Rare Chromosome
duplication of the entire short arm of chromosome 12 In many cases, there is an additional chromosome change that involves the short arm of chromosome 13, 14, 15, 21 or 22 that is not expected to affect the outcome In Group 2 are nine people with a duplication of just part of 12p The size of the duplication varies from very small to quite large
Interstitial deletion of chromosome 12q: Genotype-phenotype
Interstitial deletions of chromosome 12q are rare, with only 11 reported cases in the literature We recently described two cases with cyto-genetically identical interstitial deletions of the long arm of chromosome 12 Here, we report on a third patient, a 26-month-old male with a cytogenetically-identical interstitial deletion: 46,XY,del(12
12–2 Chromosomes and DNA Replication
12 How Replication Occurs Carried out by a series of enzymes 1 DNA molecule unwinds 2 Enzymes “unzip”DNA by breaking the hydrogen bonds between base pairs 3 Free-floating complementary bases attach to the original (template) strands DNA Replication Animation

more than one chromosome You will need to look at the letters from chromosomes 12, 13, 14, and 15 to determine the eye color Count up the total number of Capital E’s and lower case e’s and compare them to the genotype conversion chart For example, if you have 8 capital E’s from chromosomes 12-15, your individual will have black eyes
