A DNA model appears ladder-like. What is the true shape of a DNA molecule called? Describe the structure of chromatin. Describe the structure of DNA. Describe the structure and function of DNA. How does DNA fit inside the cell nucleus?
There are two strands that are present in DNA which is replicated as a single molecule. The replication of one strand occurs in a continuous manner which is known as the leading strand. The other strand is known as the lagging strand because the synthesis of the strand occurs in fragments....
Intriguingly, genomes can be negatively supercoiled, (i.e., the DNA is twisted in the opposite direction of the double helix) or positively supercoiled (i.e., the DNA is twisted in the same direction as the double helix). We encourage you to follow the links we’ve provided below to ...
What is the main difference between Chromatin and chromosomes? Chromatin is a complex formed by histones packaging theDNA double helix. Chromosomes are structures of proteins and nucleic acids found in the living cells and carry genetic material. Chromatin is composed of nucleosomes. Chromosomes are ...
A mutation changes the DNA of an organism in a way that affects its offspring, either immediately or several generations down the line. The change brought about by a mutation is either beneficial, harmful or neutral. If the change is harmful, then it is unlikely that the offspring will ...
If you have only a protein, but you're denied access to the DNA coding for it, then there is no known way to make more of it, and there is no known way to turn it back into DNA. What the Central Dogma allows is the sale of functional proteins that scientists can never make more...
As I wrote about two weeks ago, Adam Gopnik, a well-known writer who’s on staff at The New Yorker, is engaging me in an Internet discussion about “ways of knowing” on the “Conversation” site ofLetter. I was going to post only when the exchange—which will involve either three or...
The only way you would have seen it over there is if you looked at something that’s not the thing you’re looking at all the time. I remember when I was an undergrad, I did a paper on the discovery of the double helix in DNA. ...
DNA:DNA, which stands for deoxyribonucleic acid, is a nucleic acid. DNA is a polymer and contains the genetic material for humans and nearly all other living organisms.Answer and Explanation: DNA is a polymer because it is a bio-molecule that is made up of monomers. The monomers DNA is ...
What is responsible for joining together the two strands of a double-stranded helix of DNA? A. covalent bonds B. hydrogen bonds C. ester linkages D. peptide bonds E. electromagnetic force Find the hydrogen-bonding force between molecules o...
