Chromatin is the condensed form of DNA wrapped tightly around the histones coiled over and over again. So technically DNA is the genetic material that rRNA (ribosomal RNA) is generated from. You can say that ribosomes the proteins themselves are transcribed originally from condensed DNA, or chromatin.
Yes, epithelial cells have ribosomes. Ribosomes are essential organelles responsible for protein synthesis in all types of cells, including epithelial cells, which line the surfaces of organs and body cavities. These ribosomes synthesize proteins that help maintain the structure and function of the epithelial cells.
Chromosomes are composed of DNA, which is a molecule that carries genetic information, and proteins that help package and organize the DNA into a compact structure. DNA wraps around proteins called histones, forming a structure known as chromatin, which further condenses into chromosomes during cell division.
No, ribosomes and vacuoles are not the same. Ribosomes are cellular structures responsible for protein synthesis, while vacuoles are membrane-bound sacs within a cell that store various substances or help maintain turgor pressure.
Homologous pairs of chromosomes are held together by a structure called the synaptonemal complex during meiosis. This complex facilitates the pairing and alignment of homologous chromosomes, allowing for genetic recombination or crossing over. Additionally, cohesion proteins help maintain the connection between sister chromatids within each homologous chromosome.
Ribosomes synthesize proteins by translating messenger RNA (mRNA) into amino acid sequences. They help in protein folding and modification to ensure proper structure and function. Ribosomes play a crucial role in maintaining cellular homeostasis and regulating gene expression.

DNA and idk the other one or are you looking for chromosomes are composed of two chromatids held together by a centromere

Telomeres are necessary components of linear chromosomes because they protect the ends of the chromosomes from deteriorating or fusing with other chromosomes. They also help maintain the stability and integrity of the genetic information stored in the chromosomes during cell division.

Proteins in a cell provide structure by forming filaments and networks that help maintain cell shape and integrity. They also contribute to the structure of organelles within the cell, such as the cytoskeleton and cell membrane. Additionally, proteins play a role in cell adhesion and cell-to-cell communication, which are essential for maintaining tissue structure and function.
The centrosome is the organelle responsible for organizing the motion of chromosomes during cell division. It contains a pair of centrioles that help to pull apart the chromosomes by forming spindle fibers.
Proteins help condense chromosomes by binding to the DNA and causing it to coil and fold into a more compact structure. This helps organize the genetic material and allows it to fit inside the cell's nucleus.

Spindle fibers attach to the centromeres on the sister chromatids.
The number and structure of chromosomes help determine evolutionary relationships between species. Chromosome comparison helps to provide evidence of the relationships in a species.
