Chromatid (Greek khrōmat- 'color' + -id) is one copy of a newly copied chromosome which is still joined to the original chromosome by a single centromere.
Before replication, one chromosome is composed of one DNA molecule. Following replication, each chromosome is composed of two DNA molecules; in other words, DNA replication itself increases the amount of DNA but does not increase the number of chromosomes. The two identical copies—each forming one half of the replicated chromosome—are called chromatids.[1]During the later stages of cell division these chromatids separate longitudinally to become individual chromosomes.[2]
Chromatid pairs are normally genetically identical, and said to be homozygous; however, if mutation(s) occur, they will present slight differences, in which case they are heterozygous. The pairing of chromatids should not be confused with the ploidy of an organism, which is the number of homologous versions of a chromosome.
Chromonema is the fibre-like structure in prophase in the primary stage of DNA condensation. In metaphase, they are called chromatids.
The answer for this is Glucose
Chemical bonds.
Chemical bonds hold the atoms of a molecule together thereby forming covalent bonds, when two atoms share electrons.
Answer:
, electricity is just electrons (sub atomic particles) moving through a conductor. Light is also just subatomic particles moving through a conductor (1.e. transparent medium) and both are part of the electromagnetic spectrum.
In eukaryotic cells the DNA can be found in the nucleus mainly. so DNA replication takes place in the nucleus during the S phase of the cell cycle.
Also in eukaryotic cells there are mitochondria and chloroplasts (plants) and these have circular DNA and they also get replicated (according to their own mechanism).
Prokaryotic cells don't contain a nucleus. They do not contain DNA in the cytoplasm and thus the DNA replication will take place here.
I really hope this helps!
