give an example of something that might stop a cell from checking things during the cell cycle
Answer:
A checkpoint is one of several points in the eukaryotic cell cycle at which the progression of a cell to the next stage in the cycle can be halted until conditions are favorable. ... The G2 checkpoint ensures all of the chromosomes have been replicated and that the replicated DNA is not damaged before cell enters mitosis.
A mutation in a tumor suppressor gene may stop a cell from checking things during the cell cycle.
Tumor suppressor genes are normally expressed genes that control the progression of a cell through the cell cycle.These genes (tumor suppressor genes) act to repair mutations that occurred during DNA replication, slow down cell division, activate programmed cell death pathways (i.e., apoptotic pathways, etc).For example, p53 is a tumor suppressor gene capable of controlling cell division rate by keeping cells from proliferating in an uncontrolled manner.In consequence, mutations of the p53 gene are often observed in cancer cells that lost their ability to regulate the rate at which they grow.In conclusion, a mutation in a tumor suppressor gene may stop a cell from checking things during the cell cycle.

The fact that choanoflagellates and collar cells of sponges resemble each other supports the inference that ________. Group of answer choices choanoflagellates are animals choanoflagellates are more closely related to sponges than they are to protists choanoflagellates and sponges evolved similar cell structures through convergent evolution choanoflagellates and sponges are sister groups
Answer:
choanoflagellates and sponges are sister groups
Explanation:
The choanoflagellates are small unicellular organisms belonging to the Protista kingdom. These microorganisms are collared flagellates morphologically similar to the choanocyte cells of animal sponges, which have a central flagellum surrounded by a collar of microvilli. In consequence, it has been suggested that choanoflagellates may represent the closest living relatives of primitive metazoans (i.e., they are sister groups to sponges). This hypothesis has recently been supported by both molecular phylogenetic and comparative genomic analyses.

Helicase is an enzyme responsible for unwinding the double helix of the DNA by breaking apart the hydrogen bonds between each of the base pairs. Which phase of the cell cycle is helicase most likely active?
A) S
B) М
C) G1
D) G
Helicase is an enzyme responsible for unwinding the double helix of the DNA by breaking apart the hydrogen bonds between each of the base pairs. Helicase is more active in the S phase of the cycle. Option A is the correct answer.
What are the events of the cell cycle?
The cell cycle consists of the interphase and the cell division phase, where the cell division takes a little time in comparison to the interphase. The parent cell spends the majority of its time in the cell cycle's interphase and less time in the cell division phase.
There are three phases in the cell cycle's interphase: G1, S, and G2. The cell grows in both the G1 and G2 phases, while the DNA replicates in the S phase.
Hence, helicase is an enzyme that is responsible for unraveling the double helix of DNA by breaking apart the hydrogen bonds between each base pair. Helicase is more active in the S phase of the cell cycle. Option A is the correct answer.

Drag one of the nucleotides to a corresponding nitrogenous base on one of the two strands. What is
the role of DNA polymerase in this process?
Answer:
This enzyme is responsible for the production of DNA molecules from RNA molecules.
Explanation:
DNA polymerase is a type of enzyme that produces DNA molecules from RNA molecules. The enzymes play a vital role in the replication of DNA in which the enzyme produces two identical copies of DNA from one original DNA molecule. This replication of DNA is very important for cell division as well as growth of the organisms. Without this replication, no mitosis occurs in the body that leads to no growth of the organism so we can say that this enzyme plays a great role in growth of an organism.
The process of the formation of the new from the old DNA is called is replication.
The enzyme responsible for the formation of DNA replication is DNA polymerase.
The things required in the formation of new DNA is as follows:-
DNADNA polymeraseDNA ligaseThe function of the DNA polymerase during the time of DNA replication is to get the nucleotide as a monomer to join together by the DNA ligase. The nucleotide joins together in the 5' to 3' direction.
The drag of one nucleotide from the sequence leads to the mutation. These lead to the form of the infected protein and form the abnormal character.
