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.
What are DNA molecules that shorten and thicken during cell division known as?
DNA molecules that shorten and thicken during cell division are known as chromosomes. Each chromosome consists of tightly coiled DNA and proteins, allowing the genetic material to be efficiently organized and separated during cell division. In humans, for example, there are 46 chromosomes in each somatic cell, which ensure proper distribution of genetic information to the daughter cells.
How many coiled DNA molecules has an S phase have at the end?
At the end of the S phase, each DNA molecule is duplicated and consists of two coiled sister chromatids. This results in each chromosome having two identical copies of DNA.
What consists of DNA tightly coiled around proteins?
Chromosomes
X-ray diffraction photographs by wilkins and Franklin suggest that?
DNA molecules are arranged as a tightly coiled helix. (:
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.
The huge molecules are coiled in to hot dog shaped structures called?
Chromosome(s)
What is tropocollagen?
n.The molecular component of a collagen fiber, consisting of three polypeptide chains coiled around each other.
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 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.
What does a a DNA molecule consist of?
