Answer:
chromosomes are made of DNA
Step-by-step explanation:
Chromosomes are molecules formed by DNA and some proteins. In other words, chromosomes are made of DNA.
These proteins that can be present in chromosomes have the junction of wrapping DNA, reducing its length to the maximum, so that it is possible to create chromosomes. these proteins remain associated with the chromosome to prevent the DNA from unfolding.
We humans have 46 chromosomes, with the exception of sex cells that have half of that, that is, 23 chromosomes.
