when dna replication start​

Ask: when dna replication start​

Answer:

Where does DNA replication start?

Where does DNA replication start? How many origins of replication are there in a cell? How does DNA replication start? DNA replication starts with the binding of proteins to the origin of replication, opening up a replication bubble in the DNA.

when does DNA replication happen?​

Ask: when does DNA replication happen?​

Answer:

DNA replication occurs during the S-stage of interphase. DNA replication (DNA amplification) can also be performed in vitro (artificially, outside a cell). DNA polymerases isolated from cells and artificial DNA primers can be used to start DNA synthesis at known sequences in a template DNA molecule.

Ask: During which of the following process a new copy of a DNA molecule is precisely synthesized?
A. Transformation B.Transcription
C. Translation
D. Replication

Answer:

D.Replication

Explanation:

During Replication a new copy of a DNA molecule is precisely formed.

A scientist investigated DNA replication in two groups of cells,

Ask: A scientist investigated DNA replication in two groups of cells, labeled A and B. She injected radioactively labeled nucleotides into cells of each group and allowed DNA replication to begin. When replication was halfway completed, she injected a drug into the cells to stop replication. She then examined the cells to determine the distribution of the newly-synthesized DNA. She found each cell of group A had many segments of new DNA in its nucleus, while each cell of group B had a single segment of new DNA in its cytoplasm. What can the researcher conclude about the cells?

Note: Are these the choices in this question? If these are the choices, you can consider my answer.

a) Group B cells are eukaryotic because they must have a single origin of replication.

b) Group A cells are prokaryotic because they must have many origins of replication.

 c) The cells in group B are prokaryotic because they replicate their DNA in the cytoplasm.

 d) The cells in group A are eukaryotic because they replicate their DNA in the cytoplasm or nucleus.

The correct answer is C. The cells in group B are prokaryotic because they replicate their DNA in the Cytoplasm.

We have two types of cell which are the eukaryotic cell and the prokaryotic cell. The eukaryotic cell has a nucleus that contains its genetic material however prokaryotic cell lack nucleus but has a region called nucleoid which contains its genetic material.

The result of the experiment where group A had many segments of new DNA in its nucleus, while each cell of group B had a single segment of new DNA in its cytoplasm clearly states where the DNA replication occurs. Since eukaryotic cell has a nucleus, thus the DNA replication occurs in the nucleus. This is evident in cell A where the DNA segments are found. On the other hand, since prokaryotic cell do not have nucleus thus its DNA segment is found in the cytoplasm which coincides with the situation on the cell B. Therefore, we can conclude that cell A is a eukaryotic cell and cell B is a prokaryotic cell

when DNA replication starts​

Ask: when DNA replication starts​

Explanation:

DNA replication initiates at specific points, called origins, where the DNA double helix is unwound. A short segment of RNA, called a primer, is then synthesized and acts as a starting point for new DNA synthesis. An enzyme called DNA polymerase next begins replicating the DNA by matching bases to the original strand.

Answer:

DNA replication starts with unwinding of DNA duplexes which are held together by hydrogen bond. Helicases move along the double stranded DNA and separate the strands by breaking hydrogen bonds between base pairs
