Determine two important differences between heterochromatin and euchromatin region. Introduction: Chromatin can be defined as a complex, threadlike structure made up of DNA and proteins foundin eukaryotes. An important function of chromatin is to package very long DNA molecules into amore compact, denser structure. The packaging of the DNA helps not only to protect the genetic information from damage but also to regulate the transcription process. Proteins involved in the formation of chromatin are mainly histoneproteins. Histones are basic in nature and therefore readily interact with acidic DNA. Chromatinis classified into two types – heterochromatin and euchromatin.

Two nonhomologous chromosomes have the following segments, where * represents the centromere: *ABCDEFG , *RSTUVWX. Name the type of chromosomal rearrangements that would produce each of the following chromosomes. *ABABCDEFG , *ABCD , GFEDCBA*RSTUVWX , *RSWVUTX , *ABCWX , *RSTUVDEFG . Which of these types of abnormalities are most likely embryonic lethal and which ones are not usually a problem for the individual carrying them? Briefly explain why.

An individual is heterozygous for a reciprocal translocation, with the following chromosomes: A • B C D E F A • B C V W X R ST • U D E F R ST • U V W X Q. Draw the products of alternate, adjacent-1, and adjacent-2 segregations.

In a germline progenitor cell before DNA replication (2N), a translocation occurred between a telocentric and submetacentric chromosome resulting in a translocation heterozygote. The location of the translocation is illustrated below. Draw the Prophase I pairing conformation that would result from this translocation. The four types of chromosomes you have now can be labeled as follows: T-WT (telocentric wild type), T-TL (telocentric translocation), SM-WT (submetacentric wild type), and SM-TL (submetacentric translocation). Using these labels, list (please do not draw) the possible outcomes of Anaphase I and the possible phenotypes for each outcome. Please explain your reasoning for each phenotype in a few words. asap
