when does a dark reaction occur? light reaction chlorophyll traps sunlight and uses energy to split the water molecule in half; hydrogen combines with a carrier molecule and is taken to the dark reaction; ADP + P+ energy -->ATP-used in dark reaction
Types of chromosome abnormalities. There are many different types of chromosome abnormalities that require clinical care by a physician or other healthcare professional.Listed in the directory below are some, for which we have provided a brief overview.

Altering nucleotide sequences most often results in nonfunctioning proteins. Mutations cause changes in the genetic code that lead to genetic variation and the potential to develop disease. Gene mutations can be generally categorized into two types: point mutations and base-pair insertions or deletions.Point mutations are the most common type of gene mutation.ommon errors that occur during cell division can result in point mutations and frame shift mutations. Mutations during cell division can lead to replication errors which can result in the deletion of genes, translocation of portions of chromosomes, missing chromosomes, and extra copies of chromosomes.
