In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.

What are collided structures made of DNA and proteins?
Chromosomes are coiled structures made of DNA and proteins. Chromosomes form after DNA replicates; prior to replication, DNA exists as chromatin. Chromosomes contain genes, which code for proteins. Human cells normally have 46 chromosomes, made up of two sets of chromosomes, one set inherited from each parent.
Is threadlike structures made of DNA molecules that contain the genes?
The thread-like structure made of DNA molecules that contain the genes is called Chromosome.
Which of the following are threadlike structures within the nucleus that contain DNA?
The threadlike structure in the nucleus that contains genetic material is chromosomes.
Which of the following is composed of DNA and protein?
Chromatin is the material that makes up a chromosome that consists of DNA and protein. The major proteins in chromatin are proteins called histones.
What are proteins made of?
Proteins are made up of hundreds or thousands of smaller units called amino acids, which are attached to one another in long chains. There are 20 different types of amino acids that can be combined to make a protein.
Where are proteins made?
Ribosomes are the sites where proteins are synthesised. The transcription process where the code of the DNA is copied occurs in nucleus but the main process of translating that code to form other protein occurs in ribosomes.
What are the threadlike structures made of DNA?
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
What are genes made of?
Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases.
What is meant by an allele?
An allele is one of two or more versions of a gene. An individual inherits two alleles for each gene, one from each parent. ... Though the term allele was originally used to describe variation among genes, it now also refers to variation among non-coding DNA sequences.
What are the threadlike structures?
Chromosomes: Chromosomes are the threadlike structures in the nucleus of a cell. In the human body, almost all cells have chromosomes.
What structure in the nucleus contains the DNA?
Chromatin describes the material that makes up chromosomes, which are structures within the nucleus that are made up of DNA, the hereditary material. You may remember that in prokaryotes, DNA is organized into a single circular chromosome. In eukaryotes, chromosomes are linear structures.
What structure that contains DNA and regulates genes?
The nucleus is a membrane-enclosed organelle, found in most eukaryotic cells, which stores the genetic material (DNA).
What is the name of the threadlike material in the nucleus labeled #9 which is composed of DNA and proteins?
The blueprint for the reproduction and the maintenance of each organism is found in the nuclei of its cells, concentrated in elongated, threadlike structures called chromosomes. These complex structures, consisting of DNA and proteins, contain the basic units of heredity, called genes.
What is DNA and its structure?
DNA is made up of molecules called nucleotides. ... Nucleotides are attached together to form two long strands that spiral to create a structure called a double helix. If you think of the double-helix structure as a ladder, the phosphate and sugar molecules would be the sides, while the base pairs would be the rungs.
What are DNA and proteins immersed in?
The nucleus stores chromatin (DNA plus proteins) in a gel-like substance called the nucleoplasm. To understand chromatin, it is helpful to first consider chromosomes. Chromatin describes the material that makes up chromosomes, which are structures within the nucleus that are made up of DNA, the hereditary material.
