Answer:
In this case, Gibberellic acid acts as a transcription regulator
Explanation:
Gibberellic acid is a hormone that activates the transcription of genes during growth. The genes that encode for regulators of the gibberellin signaling pathway were manipulated in order to increase grain yields during the green revolution
Answer:
Some forms of chromatin modification can be passed on to future generation of cells
Acetylation of histone tails in chromatin allows access to DNA for transcription
DNA is not transcribed when packaged tightly in a condensed form
methylation of histone tails can promote condensation of the chromatin
Explanation:
chromatin modifications that can be passed on includes epigenetic modifications that are heritable changes made to the chromatin structure that does not involve the DNA sequences. Some epigenetic modifications include DNA methylation and Histone modifications. examples of histone modification include acetylation, methylation, phosphorylation, ubiquintylation etc. All these function either in allowing the DNA become more accessible to transcritional factors or vice versa. for exmple, histone tail acetylation encourages unwounding of nucleosomes allowing transcriptional factors to have access to the DNa while histone tails methylation further tightens the nucleosomes promoting condensation of the chromatin.
Answer:
Nope. Neither fish nor humans see water or air, because both water and air, are transparent.
Explanation:
Density is mass of object per unit volume
