Chromosomes<span> first become </span>visible during<span> prophase in mitosis, and they are fully</span> visible during<span> metaphase and anaphase. They lose their visibility </span>during<span> telophase and are not </span>visible during<span> cytokinesis, which follows mitosis.</span>
Answer:
B) decreased chromatin condensation
Explanation:
The addition of acetyl groups to the histone tails results in a less packed state of chromatin. The acetylation of multiple Lys residues in the amino-terminal domains of histones H3 and H4 reduces the affinity of the entire nucleosome for DNA. It occurs since acetylation reduces the total positive charge present on histone proteins. Histone proteins are positively charged and pack the negatively charged DNA around them. Therefore, increased acetylation results in decreased condensation of chromatin. The loosely packed DNA is accessible by RNA polymerase and transcription factors for gene expression.
I'm thinking true heres why lets say you have a bird and the bird eats worms.. and all the worms in the world are gone the bird will die and what ever animal ate that bird will die and what ever animal ate that bird will die and so on
my guess
I believe the correct answer from the choices listed above is option 2. Abandoned farmland that once grew corn is now covered with bushes and small trees. These observed changes resulted directly from ecological succession. It <span> is the process of change in the species structure of an </span>ecological<span> community over time. </span>
