If a globular enzyme's DNA underwent a mutation, all of the Serine and protein amino acids would be converted to Glycine. Beta sheets' hydrogen bonds will alter.
What occurs if an amino acid sequence in a protein is altered?A protein's function may shift or disappear entirely if just one amino acid in the sequence is altered. Proteins' structure is composed of amino acids. A protein's three-dimensional structure and consequent function can vary if even one amino acid is altered.
Why do most enzymes have globules?The hydrophobic effect causes the majority of the enzymes to be globular, which is one result of all the enzymes connecting them. With regard to the subject of whether enzymes are globular proteins, the answer is yes. This is how the basic proteins that are globular balance their tertiary form.

describe how acid precipitation affects ecosystems
will give brain crown thingy
Answer: Acid rain makes such waters more acidic, which results in more aluminum absorption from soil, which is carried into lakes and streams. Trees' leaves and needles are also harmed by acids... They are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife.

The effect of disorder of checkpoints proteins and cell cycle regulation
I need help!!!!!!???
Answer:
LEARNING OBJECTIVES
Identify important checkpoints in cell division
Explain how errors in cell division are related to cancer
The length of the cell cycle is highly variable, even within the cells of a single organism. In humans, the frequency of cell turnover ranges from a few hours in early embryonic development, to an average of two to five days for epithelial cells, and to an entire human lifetime spent in G0 by specialized cells, such as cortical neurons or cardiac muscle cells. There is also variation in the time that a cell spends in each phase of the cell cycle. When fast-dividing mammalian cells are grown in culture (outside the body under optimal growing conditions), the length of the cycle is about 24 hours. In rapidly dividing human cells with a 24-hour cell cycle, the G1 phase lasts approximately nine hours, the S phase lasts 10 hours, the G2 phase lasts about four and one-half hours, and the M phase lasts approximately one-half hour. In early embryos of fruit flies, the cell cycle is completed in about eight minutes. The timing of events in the cell cycle is controlled by mechanisms that are both internal and external to the cell.
Explanation:
Regulation of the Cell Cycle by External Events
Both the initiation and inhibition of cell division are triggered by events external to the cell when it is about to begin the replication process. An event may be as simple as the death of a nearby cell or as sweeping as the release of growth-promoting hormones, such as human growth hormone (HGH). A lack of HGH can inhibit cell division, resulting in dwarfism, whereas too much HGH can result in gigantism. Crowding of cells can also inhibit cell division. Another factor that can initiate cell division is the size of the cell; as a cell grows, it becomes inefficient due to its decreasing surface-to-volume ratio. The solution to this problem is to divide.
Whatever the source of the message, the cell receives the signal, and a series of events within the cell allows it to proceed into interphase. Moving forward from this initiation point, every parameter required during each cell cycle phase must be met or the cycle cannot progress.
Regulation at Internal Checkpoints
It is essential that the daughter cells produced be exact duplicates of the parent cell. Mistakes in the duplication or distribution of the chromosomes lead to mutations that may be passed forward to every new cell produced from an abnormal cell. To prevent a compromised cell from continuing to divide, there are internal control mechanisms that operate at three main cell cycle checkpoints. 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. These checkpoints occur near the end of G1, at the G2/M transition, and during metaphase

With respect to normal base pairing, when a molecule of DNA replicates, thymine will most likely pair with 2 points
Answer: Adenine
Explanation:
The structure of the DNA double helix is complex in nature. There are two strands of DNA that are wound around each other. The nitrogenous bases are bonded with hydrogen bonding and base complementarity. According to the Chargaff's rule of base complementarity adenine always pairs with the thymine and guanine with cytosine. These nitrogenous bases are paired on the basis of hydrogen bonding. Adenine bonded with thymine through two hydrogen bonds whereas the cytosine pairs with guanine via three hydrogen bonds. During DNA denaturation these hydrogen bonds are broken whereas during DNA replication these hydrogen bonds are formed between the nitrogenous bases.

what is a tumor and what does it have to do with mitosis
ASAP
will give brainliest
Answer:
Tumors constantly undergo mitosis.
Explanation:
Tumors are (generally) considered to be cancerous; therefore, they divide uncontrollably. Tumors undergo mitosis just like any other cell in your body but can be dangerous over time if not dealt with.
Answer:
What is cancer and what does it have to do with mitosis?
Cancer: mitosis out of control
Mitosis is closely controlled by the genes inside every cell. Sometimes this control can go wrong. If that happens in just a single cell, it can replicate itself to make new cells that are also out of control. These are cancer cells.

When you by strawberry is "TEXTURE " matters? and why is that?
Answer:
Yes, it does.
Explanation:
If the strawberry you buy is all soggy and way too soft, it is likely rotten, while the normal texture we are used to shows that it is edible.
Answer:
Frozen strawberries were characterized organoleptically by a moist, soft and limp appearance, and poor shape retention. They felt very soft, moist, limp and slightly slimy in the mouth. Interior fibers had a tough texture.
Give three reason why specialized systems are necessary in large multicellular organisms
Answer:
Specialized systems are necessary in large multicellular organisms since 1. there is a division of labor between cells, 2. many individual cells cannot work together without coordination, and 3. most of the cells are not in direct contact with the outside environment

How did scientists begin to Mark divisions in the geologic time scale in response to a change they discovered in the geologic record
Answer:
Scientists began to mark division on the geologic time scale when patterns and similarities started emerging from archeological studies. Patterns such as the discovery of fossils that were formed within the same period.
Explanation:
Geologists who study matter that make up the Earth's crust (whether solid gaseous or liquid), as well as matter from other terrestrial planets and the processes that influence the formation and condition of this matter, are called geologists.
They have successfully calibrated history into various phases of time intervals. These intervals are event-based intervals. For example, you have Eons, Eras, and Periods.
An Eon is a billion years. An example is the Neoproterozoid Eon. Eons are made up of several Eras and Eras are made up of periods. An example of an era is the Mesozoic era. Whilst periods are smaller units of an era, eg. Triassic era.
As scientists deduced the causes for the formation of fossils and topographical remains/patterns, they collected events that occurred within the same time period and group them together.
This range of events became known as the geological time scale.
The age of fossils and rocks is also used to map out the calibrations on the scale.
The age of fossils and rocks is determined using the process of radioactive dating.
