As many as 25 percent of the cowboys who participated in the Texas cattle drives were AFRICAN AMERICANS.
Cattle drive was a main economic activity in the Western part of America during the 19th century. The west were known for cattle breeding and they usually have to move these cattle from the home ranches to the rail-heads where they will be bought. The distance between these two points is always great and it may takes as much as two to three months before the distances are covered. The cowboy are the ones that drive the cattle to their selling points. Texas was particular successful in cow farming and as at that time about one fourth of the cows boys are of African American origin.<span />
Answer:
The changes in the sequence of nucleotides present within a promoter is a prime cause of the defected transcriptional regulation, which may eventually result in disease. However, not every modification within the sequence of a promoter influences the regulation of transcription, it relies upon the nature and the location of the genetic defect.
When a mutation results within the sequence of a promoter region it may hamper the usual procedures of gene stimulation by affecting the step by step alignment of the transcription factors at the promoter region. Therefore, as a consequence, a mutation within the sequence of a promoter may result in the enhancement or reduction in the level of mRNA and thus protein.
is a Disaccharide molecule it is to monosccarides connected by a phosphodister bond. one example would be Maltose
hope this helps!!!!
Answer:
The common element in RNA interference treatment for aids,hepatitis,and cancer include the silencing of gene expression.
Explanation:
- Through the degradation of targeted mRNA, gene silencing is done which is very popular in the eukaryotic organism and it is a highly conserved process.
- In the treatment of aids,hepatitis,and cancer, gene therapy is needed because they cannot be cured by simple consumption of drugs.
- The treatment is carried by silencing the gene expression of the particular mRNA host by utilization of RNA interference (RNAi).
