What structure do copied sister chromatids remain attached?
Copied sister chromatids remain attached at the centromere region, which is a specific DNA sequence on the chromosome. The centromere serves as the attachment site for the spindle fibers during cell division, ensuring that each daughter cell receives one copy of the chromatid.
When DNA is replicated the copied sister chromatids remain attached to what strcture?
The copied sister chromatids remain attached to the centromere, which is a specialized region of the chromosome where the two chromatids are joined. This attachment is crucial for ensuring that each daughter cell receives one copy of each chromatid during cell division.
Sometimes genes are damaged or are copied incorrectly resulting in faulty?
When genes are damaged or copied incorrectly, it can lead to mutations. Mutations can affect how proteins are made in the body, which can disrupt normal cellular functions and potentially lead to diseases or disorders. Genes can be damaged by environmental factors like UV radiation or through errors during cell division.
What enables the copied chromosomes to separate during binary fission?
The replicated chromosomes are attached to the cell membrane by proteins called tubulin that form a structure known as the mitotic spindle. The spindle fibers pull the duplicated chromosomes apart, ensuring that each daughter cell receives a complete set of chromosomes during binary fission.
Why is the replication process is a source of few mutations?
Some mutations are due to errors in DNA replication. During the replication process, DNA polymerase chooses complementary nucleotide triphosphates from the cellular pool. Then the nucleotide triphosphate is converted to a nucleotide monophosphate and aligned with the template nucleotide. A mismatched nucleotide slips through this selection process only onece per 100,000 base pairs at most. The mismatched nucleotide causes a pause in replication, during which it is excised from the daughter strand and replaced with the correct nucleotide. After this so-called proofreading has occurred, the error rate is only one per 1 billion base pairs.
Is proteins copied from DNA?
no sorry
What are proteins called?
Special proteins are enzymes. Enzymes are not made by the body, DNA is read and copied by these special proteins.
Which macromolecules are copied and pass genetic informaation to the new cells?
DNA molecules are copied and pass genetic information to the new cells. The process of coping is called replication. Nucleotide is the unit of DNA molecule.
What is a nucleotide substitution error?
Before you know what a nucleotide substitution error is, you have to know what a nucleotide is. A nucleotide holds the DNA strand together and helps make copies. When a Strand is ready to be copied, Let's say one nucleotide reads for G(Guanine), then another nucleotide would be added, which would mean C (Cytosine) would be added. A substitution error would mean that, that instead of Cytosine being added, Thymine, Adenine, Uracil, or Guanine could be added, resulting in a mutation.
What organelle is used for making proteins?
In a cell, ribosomes make proteins with amino acids based on the RNA blueprints copied from the DNA.
What structure do copied sister chromatids remain attached?
Copied sister chromatids remain attached at the centromere region, which is a specific DNA sequence on the chromosome. The centromere serves as the attachment site for the spindle fibers during cell division, ensuring that each daughter cell receives one copy of the chromatid.
What is the relationship between genes and proteins?
DNA Genes and Proteinthe gene is a subunit of DNA, one strand of DNA is copied into mRNA which is then translated into proteins
When DNA is replicated the copied sister chromatids remain attached to what strcture?
The copied sister chromatids remain attached to the centromere, which is a specialized region of the chromosome where the two chromatids are joined. This attachment is crucial for ensuring that each daughter cell receives one copy of each chromatid during cell division.

Genes can be damaged by environmental factors like UV radiation or through errors during cell division.
When DNA has replicated the copied sister chromatin's remain attached to what structure?
After DNA replication, the copied sister chromatids remain attached at a region called the centromere. The centromere holds the sister chromatids together until they are separated during cell division. This attachment is crucial for proper chromosome segregation during mitosis and meiosis.
What determined which proteins a cell make?
The answer is "DNA". It depends on the parts of the DNA that are activated and what part of the RNA-model is an intron or an exon. Only the exons get copied as RNA goes to the ribosomes, where proteins are made.
What enables the copied chromosomes to separate during binary fission?
The replicated chromosomes are attached to the cell membrane by proteins called tubulin that form a structure known as the mitotic spindle. The spindle fibers pull the duplicated chromosomes apart, ensuring that each daughter cell receives a complete set of chromosomes during binary fission.
