Are chromosomes made of DNA RNA and protein?
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. DNA and histone proteins are packaged into structures called chromosomes.
What are chromosomes made of DNA and proteins?
Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.
What is DNA and RNA and proteins made of?
The gene’s sequence is like language that instructs cell to manufacture a particular protein. An intermediate language, encoded in the sequence of Ribonucleic Acid (RNA), translates a gene’s message into a protein’s amino acid sequence….I.a. The DNA, RNA and Proteins.

What is chromosome made up of Class 9?
Each chromosome is made up of two components (i) Deoxyribonucleic acid (DNA) (ii) Proteins (e.g.; his tones and acidic proteins) These consist of two (unreplicated) or four (duplicated) arms and a primary constriction or centromere which gives them a particular shape due to its position.
How are chromosomes and proteins?
Structural proteins help the DNA fold into the intricate configurations within the packaged chromosome. DNA in chromosomes is associated with proteins and this complex is called chromatin. These proteins mediate DNA replication, gene expression, or represent structural proteins important in packaging the chromosomes.
How are chromosome formed?
A single length of DNA is wrapped many times around lots of proteins? called histones, to form structures called nucleosomes. These nucleosomes then coil up tightly to create chromatin loops. The chromatin loops are then wrapped around each other to make a full chromosome.
What is a chromosome made of?
A chromosome is made up of proteins and DNA organized into genes. Each cell normally contains 23 pairs of chromosomes.
How are proteins built from RNA?
Ribosomes make proteins using ribosomal RNA (rRNA). The ribosome reads the instructions found in the messenger RNA molecules in a cell and builds proteins from these mRNAs by chemically linking together amino acids (these are the building blocks of proteins) in the order defined by the mRNA.
Are chromosomes made up of RNA?
The chromosomes of a eukaryotic cell consist primarily of DNA attached to a protein core. They also contain RNA. DNA wraps around proteins called histones to form units known as nucleosomes. These units condense into a chromatin fibre, which condenses further to form a chromosome.
Do chromosomes have RNA?
