what was the key factor that allowed Hershey and Chase to show that DNA alone carried the genetic information of a bacteriophage?
Explanation:
DNA contains phosphorus, but protein does not. Protein contains sulfur, but DNA does not. This allowed radioactive phosphorus and radioactive sulfur to identity each molecule specifically.
[tex] \mathbb \fcolorbox{green}{red}{ STAY \: STRONG}[/tex]
[tex] \mathfrak \fcolorbox{green}{red}{BE \: BRAINLY }[/tex]
In the DNA structure there is phosphorus present while protein does not contain phosphorus but it contains sulfur while DNA does not which allowed radioactive phosphorus and radioactive sulfur to identity each molecule specifically.
What is Hershey and Chase experiment?Hershey-Chase experiment was the final experiment which is also called as the Waring Blender experiment. In this experiment, they showed that phages only injected their DNA into host bacteria, and that the DNA served as the replicating genetic element of phages.
They used this experiment to prove that DNA is the genetic material. [tex]T_2[/tex] Bacteriophage that was grown in isotopic medium radioactively labels a specific viral component. Two types of isotopic media were used.
Viruses that were grown in radioactive sulfur (35S) contained radiolabeled proteins.Viruses grown in radioactive phosphorus (32P) had radiolabeled DNANext, the virus was allowed to infect a bacterium (E. coli) and the virus and bacteria were then separated through centrifugation. After centrifugation, the larger bacteria formed a solid pellet, while the smaller viruses remained in the supernatant. The pellet of bacteria was found to be radioactive when infected with 32P-virus (DNA), but not with 35S-virus (protein).
This provided proof that DNA was the genetic material because DNA had been transcribed into bacteria, not proteins.
Thus, in the DNA structure there is phosphorus present while protein does not contain phosphorus but it contains sulfur while DNA does not which allowed radioactive phosphorus and radioactive sulfur to identity each molecule specifically.

Yeast cells are eukaryotic. What does this mean? in your own words
Answer:
Yeast cells are eukaryotic which means that they have a membrane-bound nucleus that holds their genetic information.
Eukaryotic cells also contain membrane-bound organelles such as:
Mitochondria responsible for energy productionRibosomes responsible for protein synthesisCell wall that protects the cell from the environmentThe Golgi apparatus that packages proteinsIt also means that their cellular complexity is different from Prokaryotic organisms which lack membrane-bound structures for example the nucleus. Prokaryotic cells are mostly small and simple and Eukaryotic cells are typically a lot bigger and more complex.

Suppose that a patient is diagnosed with a new disease caused by the buildup of waste material in the body's cells. Which organelle is most likely malfunctioning in the patient's cells?
a) Golgi apparatus.
b) lysosome.
c) ribosome.
d) endoplasmic reticulum.
Lysosome organelle is most likely malfunctioning in the patient's cells (option b),.
The organelle most likely malfunctioning in the patient's cells is the lysosome. Lysosomes are membrane-bound organelles that contain enzymes responsible for breaking down waste materials, cellular debris, and foreign substances. They play a vital role in cellular waste disposal and recycling.
In this case, the patient is diagnosed with a disease caused by the buildup of waste material in the body's cells. This suggests that there is a problem with the breakdown and disposal of waste materials within the cells.
The Golgi apparatus is responsible for modifying, sorting, and packaging proteins for transport within or outside the cell. It is not directly involved in waste material breakdown.
Ribosomes are responsible for protein synthesis and are not directly involved in waste material breakdown either.
The endoplasmic reticulum (ER) is involved in protein synthesis, lipid metabolism, and detoxification. However, its dysfunction would not directly result in the buildup of waste material in the cells.
Therefore, considering the role of lysosomes in waste material breakdown, it is most likely that the malfunctioning organelle in the patient's cells is the lysosome. This malfunction would lead to the accumulation of waste material, causing the disease symptoms.

In terms of structure and function how do the vacuoles in a typical plant cell compare to those of a typical animal cell
Answer:
Vacuoles in animal cells do NOT help the cell take its shape, however, in plant cells, vacuoles are larger, and DO affect the shape of the cell.
The function of the vacuole in plants is different from that in animals, as the vacuole in animals is smaller, while in plants it is larger and pushes the nucleus to one side while consisting of water and other materials.
What is the significance of the vacuole in plants and animals?Vacuoles are cell organelles found in both plants and animals, in plants, vacuoles are large, fluid-filled structures that occupy a large portion of the cell, and they perform several important functions, including storing water and helping to maintain the shape of the cell, while in animals, vacuoles are smaller and less in number than in plants, as they have a variety of functions, like storing waste materials, etc.

C o all new cells come from preexisting cells
do all living things are made of one or more cells
Answer:
A (if it is a multi-answer question) also B. Even also C.
Explanation:
C is definitely not the correct answer because germs and microbes are living things and are made of only 1 cell. The cell is also the smallest unit of life because it is called "the building blocks of life", so it has to be the smallest unit of life. Even C, because cells multiply using an existing cell, just like we humans reproduce. First, it duplicates all of its parts, or contents, including the DNA, then they split to create a new cell, (or if i'm incorrect, 2).

Why is ATP known as the energy currency?
5 line answer plz
Answer:
ATP is commonly referred to as the "energy currency" of the cell, as it provides readily releasable energy in the bond between the second and third phosphate groups. ... As a result, cells within the human body depend upon the hydrolysis of 100 to 150 moles of ATP per day to ensure proper functioning.In addition to providing energy, the breakdown of ATP through hydrolysis serves a broad range of cell functions, including signaling and DNA/RNA synthesis. ATP synthesis utilizes energy obtained from multiple catabolic mechanisms, including cellular respiration, beta-oxidation, and ketosis.

A cross between two mice with long tails and brown fur produced the four types of offspring as listed.
• Long-tailed with brown fur
• Long-tailed with white fur
• Short-tailed with brown fur
• Short-tailed with white fur
Which genetic mechanism best explains the results of this cross?
A independent assortment
B. Crossing-over
C. gene linkage
D. dependent assortment
Answer:
B
Explanation:
The genetic mechanism that best explains the results of this cross is independent assortment. The correct option is A.
What is independent assortment?According to Mendel's law of independent assortment, alleles from two (or more) different genes are sorted into gametes independently of one another.
In other words, the allele received by a gamete for one gene has no effect on the allele received for another gene.
Independent assortment occurs when alleles from at least two genes are assorted into gametes independently.
As a result, the allele inherited by one gamete has no effect on the allele inherited by the other gametes. Mendel observed that the transmission of various genes appeared to be separate events.
Independent assortment is the genetic mechanism that best explains the results of this cross.
Thus, the correct option is A.

What flower has an ugly bud but a beautiful blossom?
Explanation:
Caladiums are tropical to sub-tropical plants grown mainly for their exquisite, colorful leaves. These foliage plants occasionally have a surprise up their metaphorical sleeve. Blooming on caladium plants isn’t common, but tubers planted in favorable locations tend to produce small flowers. These inflorescences aren’t as impactful as a rose or dahlia but have their own charm and, sometimes, a strong pleasant scent. There are several schools of thought on what to do with caladium flowers. While some growers believe pinching them off helps force energy to the tubers, others leave the small blooms with no ill effect on the plant.
