gene is a segment of dna that carries instructions for making a protein.
chromosome consist of gene
A segment of DNA that makes up a gene which may codes for a particular product.
Genes and alleles are related because alleles are inside a gene. Genes are made up by alleles. A gene is DNA. The allele is like piece of DNA inside a gene.
In eukaryotes, gene expression is related to the coiling and uncoiling of DNA around histone proteins, forming chromatin. When DNA is tightly coiled around histones, it is less accessible for transcription, leading to reduced gene expression. When DNA is unwound, gene expression is more likely to occur.
Genes are segments of DNA. DNA is made up of polymer of nucleotides joined together. When there is an alteration in the sequence of nucleotides, gene mutation occurs.
Through the study of DNA gene sequences they can determine which sections of the DNA have been inherited from a common ancestral species.
A change in the DNA of a gene is a mutation.
Chromosomes are made up of DNA. DNA is made up of genes.
DNA carries genetic information, the gene is the basic unit of heredity which contains a sequence of nucleotides at a given position on a given chromosome. The paired bases are in the DNA and the codons are words of 3 letters in the genetic code.
genome -> chromosome -> DNA -> gene
New DNA molecules can come from various sources in gene cloning, such as PCR amplification of a specific gene, synthesis of a gene using recombinant DNA technology, or isolation of a gene from a donor organism. These DNA molecules are then inserted into a vector, such as a plasmid, to create a recombinant DNA molecule for cloning.
DNA and histones are closely related in the process of gene expression. DNA is wrapped around histones to form chromatin, which helps regulate gene expression by controlling access to the DNA. Histones can modify the structure of chromatin, making certain genes more or less accessible for transcription. This interaction between DNA and histones plays a crucial role in determining which genes are expressed in a cell.
