Check out Part II of this post to see how this image would look with the biggest chromosome in the human nucleus (chromosome 1).
Pretty cool! The nucleus looks so tiny. And of course there's not one but two copies of chromosome 21 packed in there. And 44 other chromosomes too...all of which are longer than chromosome 21. Chromosome 1, the longest human chromosome, is 5.3 times longer than chromosome 21.
Calculations:
I found information on human chromosome size from the statistics associated with the most recent version of the human genome (hg38). I found a couple of diameters for human cheek cells on-line and took the middle value of 50 μm (microns...a millionth of a meter).
Chromosome 21 is 46,709,983 bp (base pairs) in length. The length of a nucleotide incorporated in DNA is 0.34 nm (nanometers...a billionth of a meter).
Using Photoshop I made the cheek cell 1 inch wide (2.54 cm). So if 50um = 1 inch then chromosome 21 would be 158.8 inches (403.5 cm). I drew the line using Adobe Illustrator and kept adding to it until the total length was 158.8 inches.
Woah, something relayed to chemistry I just saw. My chemistry was never been a great experience but your share is wonderful and helpful for many students.
ReplyDeleteHey what a brilliant post I have come across and believe me I have been searching out for this similar kind of post for past a week and hardly came across this. Thank you very much and will look for more postings from you. ewapoker

ReplyDeleteThis is an interesting comparison between two important components of the human body. The human chromosome is a threadlike structure found in the nucleus of cells that contains genetic information, while the human nucleus is a membrane-bound organelle that houses the chromosomes and other important genetic material. It is clear that both the chromosome and the nucleus play a vital role in the functioning of the human body.
ReplyDeleteThe human chromosome and human nucleus are both integral components of the human body and are essential for life. The chromosome is a structure composed of DNA and proteins that carries genetic information and is organized into a distinctive shape.
ReplyDeleteFascinating depiction! The remarkable distinction between the diminutive nucleus and the remarkably elongated chromosome 1 is truly impressive. It's captivating to witness the intricate arrangement of two sets of chromosome 21, alongside the presence of 44 other chromosomes within the cell.
