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 does chromosome and chromatin have in common?
Chromosomes, chromatids, and chromatin share some of the same components. All three have DNA and histone proteins. All three are involved in the process of mitosis as cells divide.
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.
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.
Chromatin is a tangled fibrous mass made up of DNA and protein. The chromatin material condenses to form chromosomes during cell division. Chromosomes are composed of DNA and protein. … A chromosome consists of two identical and spirally coiled threads called sister chromatids.
Which of the following is true about the relationship between DNA genes and chromosomes *?
Chromosomes are made up of DNA and protein. Genes are sections of DNA on a chromosomes. Which of the following is true about the relationship among DNA, genes, and chromosomes? – Chromosomes and proteins make up genes, and genes make up DNA.
What is the relationship among DNA a gene and a chromosome Question 1 options?
The correct option is (a). Chromosomes are long thread-like structures present in the nucleus of a cell which contains hereditary information of the cell (genes). Genes are the part of a chromosome and made up of DNA. It controls the appearance of a set of hereditary characteristics.
