Part A - Modification of chromatin structure Which statements about the modification of chromatin structure in eukaryotes are tr

ue? Select all that apply. View Available Hint(s) Select all that apply. Some forms of chromatin modification can be passed on to future generations of cells. Deacetylation of histone tails in chromatin loosens the association between nucleosomes and DNA. Acetylation of histone tails in chromatin allows access to DNA for transcription. DNA is not transcribed when chromatin is packaged tightly in a condensed form. Methylation of histone tails in chromatin can promote condensation of the chromatin. Acetylation of histone tails is a reversible process.

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.

Softa [21]

Answer:

to deliver information about the physiological variable to the integrating center

Explanation:

The afferent or sensory  neurons function in  transmitting sensory information as action potential from the receptors to the CNS. It  synapse with the inter neurons, at the spinal cord, for a bypass to the brain for mediation, The response from the brain is integrated (synapse with the efferent neuron) in the spinal cord and conducted by efferent or motor neuron  to the effectors.

madam [21]
I believe that you are supposed to notice that the striations in the contracted muscle fibers are much closer together than the striations in the uncontracted muscle. Therefore, it would appear that somehow the striated parts of the muscle are being pulled closer together somehow. Glycerinated muscle retains the organized structural array of myosin thick filaments and actin thin filaments, actin associated proteins like troponin and tropomyosin which regulate contraction, and the functional capacity for contraction.
