DNA replication and transcription occur in the what?
DNA replication and transcription occur in the nucleus of eukaryotic cells. In prokaryotic cells, replication and transcription occur in the cytoplasm.
What factors most affect Chromosomal abnormalities?
Factors that most affect chromosomal abnormalities include advanced parental age, exposure to certain environmental toxins or radiation, and genetic predisposition. Additionally, errors during cell division or replication can also lead to chromosomal abnormalities.
Does protein synthesis occur during replication?
No, protein synthesis does not occur during replication. Replication is the process of copying DNA, while protein synthesis occurs during transcription and translation, where DNA is used as a template to create proteins.
What is chromosomal mutation about?
Chromosomal mutations involve changes in the structure or number of chromosomes in an organism's cells. This can result in genetic disorders, such as Down syndrome, or impact an individual's physical and cognitive development. Chromosomal mutations can occur spontaneously or be influenced by environmental factors.
How the chromosomal number of the cell is kept constant through mitosis?
By uniform replication of DNA and division of centomeres, the daughter nuclei receive the same number of chromosomes.
In which phase does chromosome replication occur?
Chromosome replication occurs during the S phase of the cell cycle. This is when DNA is synthesized to ensure that each daughter cell receives an identical copy of the genetic material during cell division.
DNA replication and transcription occur in the what?
DNA replication and transcription occur in the nucleus of eukaryotic cells. In prokaryotic cells, replication and transcription occur in the cytoplasm.
What are Extra-chromosomal DNA particles capable of independent replication are called?
Extra-chromosomal DNA particles capable of independent replication are called plasmids. Plasmids are circular DNA molecules found in bacteria that can replicate independently of the chromosomal DNA. They often carry additional genes that can provide advantages to the bacteria, such as antibiotic resistance.
The site where separation and replication occur is called?
Replication Fork
How do variations occur?
During evolution, chromosomal cariation in structure cannot occur due to
When does replication occur in a cell?
thrfffr
The sites where DNA replication and separation occur is called?
The sites where DNA replication and separation occur are called the replication fork, which is formed during DNA replication when the double-stranded DNA is unwound, and the centromere, which is the region of a chromosome where sister chromatids are held together before separation during cell division.
When a child is born chromosomal mutation when did the mutation occur?
During meiosis
When a child is born with a chromosomal mutation when did mutation occur?
during meiosis
Does DNA replication occur with interphase?
maybe
Why does replication have to occur?
So that the genes can be passed on.
When does replication occur during meiosis?
Interphase
