What molecule is a chromosome made of?
A chromosome is made of DNA, which consists of long chains of nucleotides. These nucleotides are composed of a phosphate group, a sugar molecule, and one of four nitrogenous bases (adenine, thymine, cytosine, or guanine).
What does a a DNA molecule consist of?
DNA molecule consists of the two chains, made up of phosphate and sugar molecules, alternately. The two chains are placed parallel to each other and are so called anti parallel to each other, because of their reverse direction to each other. Each sugar is attached to one of the base. There are four bases in DNA molecule. They are adenine, guanine, cytosine and thymine. Here adenine always pairs with thymine and guanine always pair with cytosine. The two strands are coiled like a springs around each other. Two bases are attached to each other with hydrogen bonds.
What is DNA coiled up into thread like structures called?
DNA coiled up into thread-like structures is called chromatin. Chromatin consists of DNA wrapped around proteins called histones, which helps to package and organize the genetic material inside the nucleus of a cell.
Chromatids are made of a molecule called?
Chromatids are made of DNA molecules that are tightly coiled around proteins called histones. These DNA molecules contain the genetic information that is passed from one generation to the next.
Are genes are made up of smaller molecules known as chromosomes?
Genes are segments of DNA, not smaller molecules like chromosomes. Chromosomes are long chains of DNA that contain multiple genes. Genes are specific sequences of DNA that encode information for making proteins, while chromosomes are structures that help organize and package the DNA in the cell.
What are DNA chains are coiled into structures called?
DNA chains are coiled into structures called double helices. The two strands of DNA wind around each other in a twisted ladder-like structure, forming the characteristic double helix shape. Each strand is made up of nucleotides, which consist of a sugar-phosphate backbone and nitrogenous bases.
At the end of s phase each chromosome has how many coiled dna molecules?
At the end of S phase, each chromosome has two coiled DNA molecules, also known as sister chromatids. These sister chromatids are identical copies of each other formed during DNA replication in preparation for cell division.
What consists of DNA tightly coiled around proteins?
Chromosomes

How do amino acids make proteins?
Amino acids are linked into chains by a process called translation. This happens when a ribosome attaches to the "start" end of messenger RNA (mRNA) and moves along it. The chain is called a polypeptide. The protein is the molecule that has a role in the organism. It consists of one or more polypeptide chains, each of which has to be coiled and folded into the correct shape. In eukaryotic cells, translation begins in the cytoplasm. The process is completed either * in the cytoplasm, or * in the lumen (cavity) of the rough endoplasmic reticulum. Which of these happens depends on the amino acid sequence of the first part of the chain to be synthesized. Polypeptide chains are also synthesized inside mitochondriaand chloroplasts. These organelles have their own DNA, mRNA, and ribosomes. In prokaryotic cells, polypeptides are synthesized in the cytoplasm.
