An inversion heterozygote has the following inverted some: Is this a pericentric

Question

An inversion heterozygote has the following inverted some: Is this a pericentric or paracentric inversion? What is the result if a crossover occurs in the heterozygote between F and G? For the normal chromosome above, diagram the pairing between it and a deletion of CD. On the web at the Kegg site, under procaryotes, find the bacterium Mycoplasma pneumonia M129. On the left, click on 'mpn' and then under 'Original DB', click on ZMBH; then click on the small gene map in the upper right hand comer to show the annotated chromosome. Draw the circular bacterial chromosome to scale with kb markers Locate orf274 at 470,000 (470kb) and mark its position on your map. What 2 genes are 10 kb from it on either side? Mark the position of all three genes on your map with their names. Click on a region to see a magnification of the region. Scroll down to the map position that you want- it is in the third column. Most genes with known function have a three or four letter name. i.e. nusA. Show the direction of transcription for the genes you are using. The gene is represented as an arrow showing the direction of transcription.

Explanation / Answer

1) In Pericentric Inversion centromere is within the inverted segment whereas in paracentric inversion centromere is not within the inverted segment.

For the given sequence ABCDJIHGF @ EKLM inversion occured at EFGHIJ segment and centromere is within the segment so it is Pericentric inversion.

In pericentric inversion crossing over results in duplications and deletion of genetic information.

2. )The resultant of crossing over between F & G is ABCDFGHIJ@EKLM.

3.) b) thE GENES ON EITHER SIDE OF ORF 274are MYCGE and cytadherence accessory protein
