# Drum set

< School of Music and Dance

## Introduction

Welcome to the Wikiversity School of the Drum set.
Drumming is an amazing form of art. It is an art that emphasizes tempo and style in virtually any musical genre. This class is dedicated to helping you experience the exciting world of percussion. Drumming is the heartbeat of so many different types of music. Looking for rhythmic notation, dynamics, technique, styles, instruments and more? This is the place to be!

## Description

The Drumset is a set of drums, tom-toms, snare, bass drum, and a series of cymbals, that is commonly found in popular music dating back to the 1920s. It is most commonly played with a pair of drumsticks.

# Drosophila Sex Determination

Χɴ= Drosophila Sex Determination =
In Drosophila, sex is determined by the X:autosome ratio and is independent of the Y chromosome.
XX:AA = female
X:AA = male
XX:AAA = intersex; these individuals are sexual mosaics; individual cells are either fully female or fully male sex index ratio =1 , normal demale =o.5 , male >1 , super female or meta female <0.5 , super male or meta male between 0.5 to 1 , intersex these are points to remember

## Pathway Deduction from Genetics

Phenotype examination of double mutants establish the sex determination pathway:
dsx is epistatic to tra, tra-2, Sxl
dsx and ix are indistinguishable in females; ix is placed downstream because it only effects females.
tra and tra-2 are epistatic to Sxl but not distinguishable from each other

### Sex Specific Lethality

Sxl and upstream genes effect dosage compensation, thus they result in sex-specific lethality instead of transformations.
X:autosome ratio is assessed early and then no longer needed. Once Sxl is activated, it is autoregulated in females, da, sis-a, and sis-b are only needed for initial signal first.

## Molecular Analysis of Drosophila Sex Determination
### dsx

dsx can be alternatively spliced to give 2 RNAs differing at their 3' end (they use different splice acceptor sites.
Mutations in the splice acceptor of the female specific exon lead to default use of male-specific exons. Tra and tra-2 thus promote the female specific splice rather than inhibit the male specific splice.

### tra

tra can be alternatively spliced to give sex-nonspecific RNA and female specific RNA
Non-specific RNA includes a stop codon and produces no active product. Its splicing is regulated by Sxl and unaffected by tra-2. Sxl blocks use of the non-specific acceptor site.
Sxl has no effect on tra-2 transcripts. Sxl exerts control of somatic sex solely by effects on tra.
Tra-2 is only functionally active in the presence of tra gene product. Active product of tra-2 has homology to RNA-binding domains of splicing factors.

### Sxl

Like tra-2 the active product of Sxl has homology to RNA-binding domains of splicing factors. Early Sxl expression is from a different promoter which is sensitive to X:A ration. At later times, Sxl product made from this early promoter can prevent splicing to the male exon and allow the production of female-specific RNA.

### sis-a and sis-b

Sis-a and sis-b function by counting X chromosomes. da and sis-b encode helix-loop-helix proteins which function as heterodimers. Da is supplied maternally in excess. Dosage of sis-b determines the amount of helix-loop-helix heterodimer that can bind to Sxl and activate it.

### hairy

Hairy is another helix-loop-helix protein which, when bound to sis-b makes an inactive dimer. Sxl is no longer activated in the presence of hairy protein.
