Select the correct order of the final three stades in the lytic cycle
The correct order of the final three stages in the lytic cycle is Assembly > Transduction > Release
What is a Lytic cycle ?One of the two viral reproduction cycles, the other being the lysogenic cycle, is the lytic cycle. The infected cell and its membrane are destroyed as a result of the lytic cycle. Virulent phages are bacteriophages that only utilise the lytic cycle.
Although the lytic cycle's final result is the generation of new phage offspring and the death of the host bacterial cell, this is a multistep process that requires careful synchronisation of physical processes and gene transcription.The primary distinction between the lytic and lysogenic cycles is that the lytic cycle kills the host cell, but the lysogenic cycle does not. The host cell's DNA is destroyed by viral DNA, which also halts the cell's lytic cycle.Learn more about Lytic cycle here:

Option b is correct. an antisense RNA binds to a translation inhibitor protein and prevents translation .
Most antisense RNAs in bacteria inhibit translation by competing with ribosomes for nascent mRNA translation initiation regions (TIRs). Through base pairing, antisense RNA is thought to inhibit translation or induce mRNA degradation. Many small noncoding RNAs (sRNAs) have recently been discovered in E. coli (4-6). The vast majority of these RNA molecules work as antisense oligomers by base pairing with mRNAs. Antisense RNAs regulate gene expression at multiple levels, including replication, transcription, and translation. Furthermore, synthetic antisense RNAs have been shown to effectively regulate the expression of related genes in host cells.

you take a summer vacation by the ocean in P.E.I. you love the ocean plants you see and you decided to bring some home for the fish tank. after a week or two, you notice that your plants are not thriving to live in your freshwater tank. use your knowledge you gained in this chapter to propose a reason for this
The reason that the plants are not thriving to live in your freshwater tank is due to slow growth, and lack of adequate lighting and carbon dioxide.
How to illustrate the informationFrom the information illustrated, during the summer vacation, the person saw the ocean plants and decided to bring some home for the fish tank. Plants require nutrients for the same reasons that animals do. They require them in order to germinate, grow, combat diseases and pests, and reproduce. Nutrients, like animals, are required in bigger, smaller, or trace amounts for the plant to be healthy.
Nitrogen is the growth ingredient responsible for green, leafy growth. Nitrogen, as a primary component of proteins, is found in every living cell. As a result, this nutrient is usually more responsible for stimulating plant growth than any other.
It was later noticed that after a week or two, the plants are not thriving to live in your freshwater tank. In this case, the important thing to do is to create a consistent light that will compensate for the cycle. The fact that the ocean water is salted and the nutrients gotten from the ocean is also another contributory factor to the changes noticed.

tumor suppressor genes make up another group of genes that regulate cell division. genes from this group produce proteins that signal cells when they are getting too crowded, proteins whose function is to repair dna, and still other proteins that regulate apoptosis (pre-programmed cell death). a tumor suppressor gene called p53 causes apoptosis when the cell is worn out or when defects are detected. where in the cell cycle would a tumor suppressor gene repair dna?
In the cell cycle, tumor suppressor gene will repair DNA in G2 phase.
G2 (Gap 1 phase) is the transition phase between S phase and M phase, in G2 phase cell prepare itself from mitosis.
When DNA is damaged, signaling pathways are initiated that causes cell cycle arrest in G2 phase.
p53, which is frequently disabled in a wide range of human cancers, including brain tumors, leukemias, lymphomas, sarcomas, and carcinomas of numerous tissues, including the breast, colon, and lung. The most common target of genetic alterations in human malignancies is p53, which may be involved in up to 50% of all cancers. It is also intriguing that a rare hereditary cancer syndrome, in which affected individuals develop any one of a number of different kinds of cancer, is transmitted genetically through p53 mutations. Similar to Rb, the oncogene proteins of SV40, adenoviruses, and human papillomaviruses also target the p53 protein.
the product of the p53 gene controls both apoptosis and the progression of the cell cycle. DNA damage prompts the rapid induction of p53, which triggers transcription of the Cdk inhibitor p21.As a general inhibitor of Cdk/cyclin complexes and by binding to PCNA (proliferating cell nuclear antigen), the inhibitor p21 prevents the progression of the cell cycle. The cell cycle is likely stopped as a result, giving damaged DNA time to be fixed before it reproduces. This damage-induced cell cycle arrest is prevented by the loss of p53, which results in an increase in the frequency of mutations and general genome instability. Oncogenes and tumor suppressor genes may also be altered as a result of this genetic instability, which is a characteristic of cancer cells.
