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.
Many organelles and molecules needed for cell division are formed after DNA replication and before mitosis In which phase are they formed?
The organelles and molecules needed for cell division are formed during the G2 phase of the cell cycle, after DNA replication has occurred during the S phase. This is a crucial preparation phase for mitosis, where the cell ensures it has all the necessary components for successful division.
A single piece of coiled DNA is known as?
A coiled piece of DNA is called a plasmid, found in prokaryotic cells.
DNA synthesis occurs?
during the S phase of the cell cycle, where the DNA double helix unwinds and each strand serves as a template for the synthesis of a new complementary strand. Enzymes called DNA polymerases catalyze the formation of phosphodiester bonds between nucleotides to build the new DNA strand. The end result is two identical DNA molecules, each consisting of one original strand and one newly synthesized strand.
Does protein produce DNA?
DNA are not chemically having protein. But DNA are coiled to chromatin structures by proteins called histones. DNA can interact with proteins for various reason including DNA replication.DNA are not chemically bonded with proteins. But they do interact with protins for various process including DNA replication. In nucleus, DNA coiled to form chromatin structures by histone proteins.
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.
When is DNA not tightly coiled into a chromosome?
S phase of Interphase
X-ray diffraction photographs by wilkins and Franklin suggest that?
DNA molecules are arranged as a tightly coiled helix. (:
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.
How many double helical twists does a DNA have?
Your entire genome is coiled into a double helixes and these are intern coiled up further.
Many organelles and molecules needed for cell division are formed after DNA replication and before mitosis In which phase are they formed?
The organelles and molecules needed for cell division are formed during the G2 phase of the cell cycle, after DNA replication has occurred during the S phase. This is a crucial preparation phase for mitosis, where the cell ensures it has all the necessary components for successful division.
What is formed with coiled up DNA?
Coiled up DNA, combined with protein histone, forms chromosomes.
A certain species of animal has six pairs of chromosomes How many DNA molecules are present in the nuclei of these animals during G2 phase?
During G2 phase, the cells have undergone DNA replication resulting in sister chromatids. Since there are six pairs of chromosomes, there will be 12 DNA molecules present in the nuclei of these animals.
Is DNA coiled?
Chromosomes
Are DNA molecules the largest in the body?
No, DNA molecules are not the largest in the body. The largest structures in the body are cells, which are composed of various organelles, including the nucleus where DNA is housed. DNA itself is a long, thread-like molecule that is tightly coiled to fit within the nucleus of a cell.
How are DNA molecules joined together and coiled?
DNA molecules are joined together through hydrogen bonding between complementary nucleotide bases (A-T and G-C). This forms the double helix structure. The DNA molecule is then coiled around histone proteins to form structures known as nucleosomes, which further coil and condense to form chromosomes.
What is DNA in its coiled form?
What is DNA in it's uncoiled form
