The correct answer is: B) decreased chromatin condensation
Histone modifications which include phosphorylation, methylation, acetylation and their reverse processes are post-translational modifications that can regulate gene expression. Their effect depends on the amino acid (protein) that is modified, and the combination of the other modifications.
These modifications regulate gene expression by organizing the genome into active form-euchromatin, where DNA is accessible for transcription, or inactive-heterochromatin, where DNA is less accessible for transcription.
They would try to adapt to their new surrounds. Some may die off before they are able to adapt
Answer:
C. A small, circular piece of DNA
Explanation:
A plasmid, usually circular but sometimes linear, is a small double-stranded DNA unit, which is chromosome independent and is capable of self-replication. Each plasmid carries only a few genes. Carrying only a few genes, the plasmid’s size ranges from 1 to more than 1000 kbp. Genes required for organism survival and those that are generally beneficial to the host organism, such as antibiotic resistance, are often found in plasmids [1].
Mostly plasmids can be found in bacteria, but they are also present in multicellular organisms and archaea. Plasmids usually contain at least one gene and are not considered independent life forms even though they possess separate genes from their hosts
C. Fenestrated capillaries have intracellular perforations.
