Is chromatin made of DNA or RNA?
Chromatin is a complex of macromolecules composed of DNA, RNA, and protein, which is found inside the nucleus of eukaryotic cells. Chromatin exists in two forms: heterochromatin (condensed) and euchromatin (extended).
DNA is packaged into tightly wound structures called chromosomes. … Each long string of DNA winds around structural protein spools called ‘histones’ to form a material called ‘chromatin’. The chromatin further loops and coils to form the tightly condensed chromosome structure.
Are chromosomes made of DNA?
A chromosome is made up of proteins and DNA organized into genes. Each cell normally contains 23 pairs of chromosomes.
What is chromatin made of?
Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells. Nuclear DNA does not appear in free linear strands; it is highly condensed and wrapped around nuclear proteins in order to fit inside the nucleus.
Does chromatin contain RNA?
Yes, chromatin contains RNA. It is an integral part of chromatin and plays a role in the structural organisation. Around 2-5% of total nucleic acids present in chromatin are RNA.
Is chromosome made up of chromatin?
Chromosomes are made up of a DNA-protein complex called chromatin that is organized into subunits called nucleosomes.
What is the relationship of DNA with the 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.
A genome is an organism’s complete set of DNA. If the DNA code is a set of instructions that’s carefully organised into paragraphs (genes) and chapters (chromosomes), then the entire manual from start to finish would be the genome. Almost every human’s genome, chromosomes and genes are organised in the same way.
