In the nucleus, the DNA double helix is packaged by special proteins (histones) to form a complex called chromatin.
The chromatin undergoes further condensation to form the chromosome
. So while the chromatin is a lower order of DNA organization, chromosomes are the higher order of DNA organization.
What is the relationship between DNA genes chromosomes and chromatin?
Chromatin is a substance within a chromosome consisting of DNA and protein. The DNA
carries the cell’s genetic instructions
. The major proteins in chromatin are histones, which help package the DNA in a compact form that fits in the cell nucleus.
What is the relationship between the DNA and a chromosome?
Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that
functions in one or more types of cells
in the body. Chromosomes are structures within cells that contain a person’s genes. Genes are contained in chromosomes, which are in the cell nucleus.
What is the relationship between DNA and chromosomes quizlet?
DNA contains the instructions, genes, to make proteins that tell what
genetic traits
the person will have. The DNA along with the proteins make up the chromosomes. The chromosomes are then passed on to the offspring, and with the DNA inside the chromosomes and translation of the genes, its traits are decided.
What is the relationship between DNA and chromatin quizlet?
Chromatin is the DNA and proteins that make up a chromosome. Chromosomes are the separate pieces of DNA in a cell. And Chromatids are
identical pieces of DNA held together by a centromere
.
How many genes are in a chromosome?
Each chromosome contains
hundreds to thousands of genes
, which carry the instructions for making proteins. Each of the estimated 30,000 genes in the human genome makes an average of three proteins.
Where is gene located?
Genes are found
on tiny spaghetti-like structures called chromosomes
(say: KRO-moh-somes). And chromosomes are found inside cells. Your body is made of billions of cells. Cells are the very small units that make up all living things.
Why is it important for DNA to condense into chromosomes?
Cells need to be able to organize their genetic material so that it can be sorted easily and fit into the nucleus for division. By condensing DNA into chromosomes,
cells can align each chromosome (or during meiosis, each tetrad)
, along the metaphase plate.
Is a chromosome DNA?
Each chromosome is made up of DNA tightly coiled
many times around proteins called histones that support its structure. Chromosomes are not visible in the cell’s nucleus—not even under a microscope—when the cell is not dividing.
What best describes the relationship between genes DNA and chromosomes?
Which best describes the relationship between DNA, genes, and chromosomes?
Genes are segments of DNA which form tight coils called chromosomes
.
Where is someone’s DNA found quizlet?
DNA usually exists
inside the nucleus
as uncoiled strand or “strings” called chromatin, which are held together by proteins. When the cell is ready to divide, the strings of chromatin coil up into X-shaped structures called chromosomes.
What role does DNA play in heredity?
DNA is important in terms of heredity. It packs
in all the genetic information and passes it on to the next generation
. The basis for this lies in the fact that DNA makes genes and genes make chromosomes. … Thus a person inherits half of his or her genes from each of the parents.
What is the major difference between chromatin and Chromosomes?
Chromatin is a complex formed by histones packaging the
DNA double helix
. Chromosomes are structures of proteins and nucleic acids found in the living cells and carry genetic material. Chromatin is composed of nucleosomes. Chromosomes are composed of condensed chromatin fibers.
What is the difference between DNA a gene and a chromosome chromatin quizlet?
A gene is one section of a chromosome, and a chromosome may carry many genes. What is the relationship between DNA and chromatin? D. Chromatin is the
combination of DNA packaged
around the proteins.
What is the difference between DNA chromosomes chromatin and chromatids?
So the chromatin is
a lower order of DNA organization
, while chromosomes are the higher order of DNA organization. Chromosomes are single-stranded groupings of condensed chromatin. … A chromatid is either of the two strands of a replicated chromosome. Chromatids connected by a centromere are called sister chromatids.
