The processes of transformation and transduction are important for bacteria. In transformation, the bacteria receives DNA from an extracellular donor and in transduction, DNA in a bacteriophage is taken up the by the bacteria.
These tools are used to measure or identify certain degree of occurrence depending on which specific area it is used. Thermometers are used to measure the degree of temperature in a room, area or a certain location. Moreover, probewares use electrons and the activity or heat signature in a room while liquid based uses the heat of an object to indicate how much heat energy is involved.
The Trex-Binding Factor in Muscle Creatine Kinase Enhancer has been identified and described below.
The Muscle Creatine Kinase Enhancer contains a positive control site called Transcriptional Regulatory Element X (Trex). The Trex site is critical for MCK expression in skeletal and cardiac muscle, according to research using transgenic animals and cell culture. Quantitative proteomics was used to identify the Trex-binding factor (TrexBF) as Six
a homeodomain transcription factor of the Six/sine oculi's family, from a background of about
copurifying proteins, following selective enrichment for TrexBF using magnetic beads coupled to oligonucleotides containing either wild-type or mutant Trex sites. We showed that Six4 is TrexBF in mouse skeletal myocytes and embryonic day 10 chick skeletal and cardiac muscle, but Six
is the primary TrexBF in adult mouse heart, using gel shift assays and Six-specific antisera. Six
transactivates in co transfection investigations.

The right answer is law of segregation
Mendel derives from his observations two fundamental principles, to which will be added later a third resulting. In his case, experiments on peas enabled Mendel to formulate the principles involved in heredity.
<u>Mendel discovers that:</u>
* A character can present two different forms (today called alleles or homologous genes).
* An organism inherits two factors for each trait (Mendel's hereditary factors are now called "genes").
* The dominant factor masks the recessive factor. Mendel noted the dominant factor using a capital letter and the other, the recessive, using the same letter but in lower case
.
* The two factors separate during gamete formation (Segregation law that corresponds to the separation of homologous chromosome pairs during meiosis)
.
* The pairs of factors separate independently of each other (independent segregation law that corresponds to the independent assortment of chromosome pairs homologous to metaphase 1 of the first meiotic division).
