Homework Answers
N. gonorrhoeae is a pathogen responsible for causing sexually transmitted disease gonorrhoeae. They undergo homologous recombination to bring in variation of their surface antigenic proteins. These are pilin in proteins responsible for the infection in the host and their entry in the host.
The Mut genes responsible for mismatch repair mechanism after replication for correction, can hinder the homologous recombination but still surface antigenic variation can be observed because of the presence of Mut S gene that gets mutated and results in an 3 fold increase of surface antigenic variation.

Human blood types A, B and O are associated with the carbohydrate antigens A, B and H respectively. A and B antigens are caused by an alteration of H antigen. Normally everyone can synthesize H antigen (a cell surface carbohydrate found on red blood cells and other cell types). Some people make A and/or B transferase(s) which converts the H antigen to an A and/or B antigen respectively. The H antigen is produced by a specific fucosyltransferase encoded by the...

Explain the following in terms a highschooler would understand (from article Expression of HoxD Genes in Developing and Regenerating Axolotl Limbs, 1998): DISCUSSION: Expression of HoxD genes in developing axolotl limb buds. We have examined the expression of Hoxd-8, Hoxd10, and Hoxd-11 genes in axolotl limb buds and find many similarities between the patterns of expression in axolotls and those described for other vertebrates. Similarities are most pronounced in phases I and II (Nelson et al., 1996; Shubin et al.,...

*IN PYTHON* A role-playing game or RPG is a game in which players assume the roles of characters in a fictional setting. The popularity of the epic saga told in J.R.R. Tolkien's The Hobbit and The Lord of The Rings greatly influenced the genre, as seen in the game Dungeons & Dragons and all of its subsequent variants. In most RPGs, a player creates a character of a specific archetype or class, such as "Fighter", "Wizard", or "Thief". (Note: do...
