What organelle holds genetic information in the molecule DNA?
The nucleus is the organelle that holds genetic information in the form of DNA. DNA is tightly packed into structures called chromosomes within the nucleus of eukaryotic cells.
Eukaryotic chromosomes contain both DNA and protein tightly packed together to form a substance called?
The complex of both histone and non-histone chromosomal proteins and DNA is known as chromatin.
If you unravel the DNA from all of your chromosomes how far would it reach?
If you were to unravel all the DNA in your chromosomes and line it up end to end, it would reach approximately 6 feet in length. This condensed DNA is tightly packed into the nucleus of each cell in your body to fit within the tiny space.
What is the structure in the nucleus that is composed of large amounts of DNA?
The structure in the nucleus that is composed of large amounts of DNA is the chromosome. Chromosomes consist of tightly coiled DNA wrapped around proteins called histones, and they are essential for storing and organizing genetic information. Humans typically have 46 chromosomes, which are present in the nucleus of each cell.
Why does DNA have to be tightly packaged up?
DNA needs to be tightly packaged in order to fit inside the cell's nucleus. Packaging helps to protect the DNA from damage and controls which genes are accessible for transcription. Additionally, tight packaging helps regulate gene expression by controlling the availability of specific regions of DNA.
What are tightly packed units of DNA?
Chromosomes
What eukaryotic chromosomes contain both DNA and protein tightly packed together to for a substance?
Eukaryotic chromosomes contain both DNA and protein tightly packed together to form Chromatin. Chromatin consists of DNA tightly coiled around histones. DNA and histone molecules form nucleosomes. These are all part of the structure of chromosomes.
What are DNA strands packed into?
DNA strands are packed into structures called chromosomes. Chromosomes are made up of long strands of DNA that are tightly coiled and condensed to fit inside the nucleus of a cell.
Prokaryotic cells I do not have a nuclear us so I am the result of loosely packed DNA who am I?
Loosely packed DNA can result in genes not being expressed properly.
How are chromosomes DNA related?
Chromosomes are tightly coiled structures of DNA (and proteins).
What are chromosomeswhere and when they are visible in the cell?
Chromosomes contain tightly-packed DNA, and are visible only when the cell is preparing to replicate (before mitosis/meiosis).
What molecule are the chromosomes made of?
Chromosomes are made up of DNA molecules. These DNA molecules are long strands composed of nucleotides, which are the building blocks of genetic information. The DNA in chromosomes is tightly packed and organized with proteins, forming a structure that is essential for cell division and storage of genetic information.
What organelle holds genetic information in the molecule DNA?
The nucleus is the organelle that holds genetic information in the form of DNA. DNA is tightly packed into structures called chromosomes within the nucleus of eukaryotic cells.
Why does DNA have to send messenger RNA instead of going out into the cell itself?
1. DNA is tightly packed into chromosomes; 2. t-RNA will only recognize mRNA and this is the way a protein is built.
What does the chromatin material get organised into during cell division?
During cell division, chromatin material gets organized into tightly packed structures called chromosomes. Chromosomes contain DNA that carries the genetic information of the cell, crucial for proper cell division and inheritance of genetic traits.
What is chromosome and what does it do?
A chromosome is a mix of tightly packed DNA and proteins.
How do DNA and cromosomes fit together?
Chromosomes are made of DNA. There is a huge amount of DNA in cells. DNA is typically present at a long chain of building blocks called nucleotides. Since long strands of DNA have to be stored in small spaces, they are tightly rolled and packed into structures called chromosomes
