Changes in a DNA sequence that affect an entire chromosome or multiple chromosomes?
Changes in a DNA sequence that affect entire chromosomes or multiple chromosomes can include chromosomal rearrangements such as translocations, duplications, deletions, and inversions. These changes can result in alterations in the number or structure of chromosomes, leading to genetic disorders or abnormalities. They can be caused by errors during cell division or exposure to mutagens.
What main goal of the human genome project is to?
It was meant toidentify all the approximately 20,000-25,000 genes in human DNA,determine the sequences of the 3 billion chemical base pairs that make up human DNA
Is a gene all of an organism's DNA or only a segment of DNA?
A gene is a portion on a chromosome. It is not the entire DNA which codes for all you see in an individual.

How many DNA sequences are in a chromosome?
That depends on the size of the chromosome. We can use the largest and smallest human chromosomes as examples, using size information from the Ensembl genome browser (www.ensembl.org). Human chromosome 1, the largest, is estimated to have 247,249,719 base pairs. That is, the DNA sequence in the chromosome is about 247 million base pairs long. Since DNA is double stranded, that equates to about 494 million nucleotides. The smallest chromosome, 22, on the other hand has 49,691,432 base pairs - about 50 million. Hence it has about 100 million nucleotides.

What is each one?
Each chromosome has genes on it in the form of coded base nucleotide sequence which is part of DNA.

What is the definition of chromosome mutation?
A chromosome is an organized structure of DNA and protein that is found in cells.In biology, mutations are changes to the nucleotide sequence of the genetic material of an organism.
What Is part of the DNA code on a chromosome?
The DNA code on a chromosome consists of genes, which are specific sequences of nucleotide bases that encode instructions for building proteins. These genes also include non-coding regions that regulate gene expression, such as promoters and enhancers. The DNA code on a chromosome is organized into distinct units called codons, each consisting of three nucleotides that correspond to specific amino acids in a protein sequence.
How can bacterium produce restriction enzymes that do not cleave it's DNA?
Restriction enzymes cleave DNA at a particular recognition site -- a particular sequence of nucleotides. You can imagine the following scenarios:1. The bacterial chromosome does not contain the recognition sequence2. The bacterial chromosome contains the recognition sequence, but that particular part of the DNA is either supercoiled to keep the restriction enzyme from finding the sequence, or it's single stranded as when being replicated or transcribed.3. The bacterial chromosome contains the recognition sequence, but that particular part of the DNA is methylated or modified in some other way which prevents the restriction enzyme from attaching.
