The nucleus of a cell contains genetic material and many proteins. the interaction between these proteins and genetic material forms various structures.
match each of the terms with the statement that describes the term:
part a
a. protein
b. dna
c. chromatin
d. histones
part b
1. this series of nucleotides encodes proteins.
2. these proteins regulate transcription and modifications of genetic material.
3. this folded amino acid chain is genetically encoded and performs specific functions in the cell.
4. this substance is made up of fibers that are formed in the nucleus by supercoiling genetic material.

Protein: 3. This folded amino acid chain is genetically encoded and performs specific functions in the cell.

DNA: 1. This series of nucleotides encodes proteins.

Chromatin: 4. This substance is made up of fibers that are formed in the nucleus by supercoiling genetic material.

Histones: 2. These proteins regulate transcription and modifications of genetic material.

the circled areas are referred to   as sunspots.   the sunspots are cooler than the   surrounding area.

sunspots are temporary phenomena on the photosphere of the sun that appear visibly as dark spots compared to surrounding regions. they correspond to concentrations of magnetic field flux that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.
