∙ 14y agoIt appears to have a double helix shape, similar to the structure of DNA.
If you mean as a whole, most chromosomes resemble the shape of the letter X. There may be a sex chromosome, and it may resemble the letter V in males of the species, though in that case, it is called a Y-Chromosome. During the anaphase of mitosis, they would be L-shaped.If you mean in terms of the shape of the genetic material, then chromosomes have a double-helix shape.
Licorice twists are a type of candy that often resemble a strand of DNA due to their twisted shape and appearance.
There are 1000 bases of DNA in a 1 kilobase fragment.

Semidiscontinuous DNA is a lagging strand synthesis. It is a short fragment in the structure of double helix.

A moving fragment of DNA is a transposable element, also known as a transposon. These genetic sequences have the ability to move around within a genome, causing mutations and altering gene expression. Transposons are found in both prokaryotic and eukaryotic organisms.

T cells can secrete perforin, a protein that creates pores in target cells, allowing granzymes to enter and trigger apoptosis by fragmenting the target cell's DNA. This process is an important mechanism used by T cells to eliminate infected or cancerous cells.
The longest fragment of DNA in humans is a gene called dystrophin, which is found on the X chromosome and spans about 2.4 million base pairs. Additionally, the mitochondrial genome is also a long fragment of DNA, totaling about 16,500 base pairs.
"Vector" is an agent that can carry a DNA fragment into a host cell. If it is used for reproducing the DNA fragment, it is called a "cloning vector". If it is used for expressing certain gene in the DNA fragment, it is called an "expression vector".

A laboratory might be using dideoxy nucleotides in DNA sequencing reactions, specifically in the Sanger method. Dideoxy nucleotides lack a 3’ hydroxyl group needed for DNA chain elongation, resulting in termination of DNA synthesis at specific bases. This allows for the determination of the nucleotide sequence of a DNA fragment.
