The second statement would be more correct.
False. A mutation refers to a change in the DNA sequence of a gene or chromosome, not the specific part of a chromosome that carries information about a trait.
In late anaphase and G1 of interphase, a chromosome is unreplicated and consists of a single DNA double helix. A replicated chromosome contains two identical DNA double helices.
genome -> chromosome -> DNA -> gene
Nucleotide < DNA < Chromosome < Cell < Nucleus.
DNA is primarily stored in the chromosome within the cell nucleus. Some DNA is also present in the mitochondria, which are located in the cytoplasm.
The circular DNA molecule that is not part of the bacterial chromosome is called a plasmid. Plasmids are small, extrachromosomal pieces of DNA that can replicate independently of the bacterial chromosome. They often carry genes that provide bacteria with additional functions, such as antibiotic resistance.
A chromosome is a part of DNA that consists of a long arm and a short arm connected at the center called the Centromere.
False. A mutation refers to a change in the DNA sequence of a gene or chromosome, not the specific part of a chromosome that carries information about a trait.

At the beginning of cell division, DNA and the proteins associated with the DNA coil into a structure called a chromosome. Chromosomes are visible under a microscope and contain the genetic material (DNA) of an organism.
autosomal dna, X chromosome, Y chromosome,and mitochondrial
genome -> chromosome -> DNA -> gene
every and any DNA strand can constitue to 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.
Deletions are a loss of all or part of a chromosome. Duplications produce extra copies of parts of a chromosome. Inversions reverse the direction of parts of a chromosome. Translocations occur when part of one chromosome breaks off and attaches to another.
it would be 1st chromosome. then gene. then DNA
Each chromosome has genes on it in the form of coded base nucleotide sequence which is part of DNA.
