Difference between chromosomes and DNA?
The smallest unit is the gene, which can be any length of base pairs, A, C, T, and G. All genes fit on DNA. DNA is a double helix shape, meaning it looks like a ladder twisted around in a spiral shape. The "rungs" are the bases, and the long part is made out of a sugar, deoxyribose, and a phosphate group. All that DNA is then condensed into chromosomes.
What creates dna and contains all of your individual traits?
You get DNA from your parents and the DNA get mixed and with some part of mother's and some part of father's.The process in parents that is DNA copying takes place to create copies of DNA of parents and hence this DNA go into the child.The Germ cells or the sex cells contain the individual traits.Sperm- MaleOvaries (Egg)-Female
Is DNA or RNA the master plan?
DNA is like a master plan in that it has all the plans for all the proteins the body makes. RNA is like a blueprint because it carries the information that tells a a cell how to produce a specific protein.
Can you see individual DNA strands or genes in karyotypes?
nope you see chromosomes. which are each a single tightly wound strand of DNA but you cant make out that out. can see genes at all unless your looking at a sequence or have a florescent or radioactive tag.
Is there DNA in a cell?
Yes, DNA is located in the nucleus of a cell, where it stores genetic information that determines an organism's traits. DNA is organized into chromosomes, which are passed down from one generation to the next during cell division.
What is happening to the DNA throughout all the phases?
It replicates
Why are chromosomes not condensed during all stages of the cell cycle?
Chromosomes are not condensed during all stages of the cell cycle because they need to be accessible for processes like DNA replication and gene expression. When chromosomes are condensed, it makes it difficult for the cell to carry out these essential functions.
What part of a cell are you going to find the DNA?
the nucleus contains all DNA
Is it true that DNA replication can also be called mitosis?
DNA replication is technically not part of mitosis. Mitosis is simply the splitting of the nucleus. DNA replication however is part of the interphase, which is part of the cell cycle. The DNA replication is also known as the S phase in the interphase. In this part, the DNA is replicated creating two sets of all genetic information.
Can DNA from one part of the body is similar to DNA of the other part in protein sequence structure morphology etc?
The DNA in all body cells should be identical.
Some of the portions of the chromatin are permanently condensed so that their DNA is never expressed All of these portions stain very intensely and are given a common name of?
These condensed portions of chromatin are called heterochromatin. They are tightly packed regions of DNA that are typically transcriptionally inactive, meaning the genes within them are not actively expressed. Heterochromatin appears densely stained under a microscope due to its tight packing of DNA.
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.
Where does mitosis process?
DNA replication during interphase occurs in the nucleus. All other phases of mitosis occur in the cytoplasm after the nuclear membrane is disassembled.
Why are the chromosomes not condensed during all stages of mitosis?
When replicating or during transcription, DNA needs to uncoil in order to give the proper code. When the chromosomes are condensed, it cannot uncoil itself to give any sort of message. In order for the cell to remain functional, it must be able to code DNA.
How are DNA centrimere chromosomes chromatid and chromatin are related?
Chromatid- one of two identical parts of the chromosome after "S" phaseCentromere- the point where the two chromatids crossChromosome- carries DNA in (and between) organisms.
What part of a cell's organelle is responsible for controlling all activitie's and has DNA?
the nucleus
Which part of DNA forms the double-helix structure?
All of it, that is the shape of the molecule.
