Mutation
it called mutation.
Chromosome mutations can result in changes in the number of chromosomes in a cell or changes in the structure of a chromosome. Unlike a gene mutation which alters a single gene or larger segment of DNA on a chromosome, chromosome mutations change and impact the entire chromosome.
the bacterial cell reproduces the bacterial chromosome that the human gene codes for.
nucleus → chromosome → gene
Chromosome 21 is the smallest human chromosome. Inside of the chromosome, there are 48 billion nucleotides, the building blocks of DNA.
A Mutation
The permanent change in a gene or a chromosome is called Mutation.
Mutation
Smallest to largest: Gene (a place on a chromosome); chromosome (there are 46 in human cells); and DNA (because it accounts for all the genetic material in a cell).
mutation
From smallest to largest: DNA (where DNA = short sequences of nucleotides) gene chromosome nucleus sperm cell
Chromosome mutations can result in changes in the number of chromosomes in a cell or changes in the structure of a chromosome. Unlike a gene mutation which alters a single gene or larger segment of DNA on a chromosome, chromosome mutations change and impact the entire chromosome.
A change in a gene or chromosome is called a: Mutation
gene.
Genitic change
characteristics are like traits. traits are within the gene in a cell. And a gene is among the DNA strands in a chromosome. And a chromosome is in the nucleus. and the nucleus is in the cell. And cells are in organisms.
