Answer:

<em>Geographic isolation</em>

Explanation:

Geographic isolation can be described as a term that describes the model of speciation in which a biological population becomes isolated from other members of the population and can no longer have gene flow with them.

The same scenario of gene isolation is occurring in the species of taods which live at the top of the mountains in southern Arizona. This population has become reproductively isolated fro all other species of toads within the mountain range.

Part A - Modification of chromatin structure Which statements about the modification of chromatin structure in eukaryotes are tr
Salsk061 [2.6K]

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.
