What effect does histone acetylation have on Gene 1?

Q: How does histone variation regulate gene expression in eukaryotic cells?

A: In the nucleus DNA is coiled and packed in the form of chromosomes. DNA wounds on histone and forms…

Q: What is the difference between chromatin-remodeling and histone modification?

A: In any event nine unique sorts of histone changes have been found. Acetylation, methylation,…

Q: what is the highly compacted strongly staining region of the chromosome with no transcriptional…

A: The highly compacted strongly region of the chromosome with no transcriptional activity is…

Q: Assuming each dimer binds to one unique sequence, how many unique sequences can protein dimers…

A: Proteins are biomolecules, which are made from amino acids. They are polymers of amino acids. They…

Q: Why is the p53 R273W mutation preventing p53 from binding to DNA?

A: All living things are made up of cells, which are the most basic and important unit. All of life's…

Q: do introns or 3′ untranslated regions of a gene have higher rates of nucleotide substitution?…

A: Introns are the regions that include non-coding regions of the RNA transcript. The introns are…

Q: Describe two different ways that histone modifications may alter chromatin structure.

A: Chromosomes appear at the time of cell division in the form of thread like structures inside the…

Q: how does cells prevent excess transposable elementmobilization.

A: Transposable elements (TEs) are the small segments of DNA that can move from one position to other…

Q: Examination of the histone modifications around a gene reveals an abundance of histone H3 with…

A: This gene is likely activated since the mono-methylation of the Lysine residue at position 27 in…

Q: What are some of the processes that affect gene regulation by altering chromatin structure?

A: The mechanism of encoding of proteins by a gene which regulates cellular functions is known as gene…

Gene Interactions

When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.

Gene Expression

Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.
