What did Rosalind Franklin contribute to the field of science and how did her work impact society?

Answer:

Every muscle in the body as well as the nerves that supply it are part of the neuromuscular system.

Explanation:

Communication between the brain and muscles is necessary for every movement the body makes.

The neuromuscular system, which is made up of nerves and muscles, controls respiration as well as how the body moves when you want it.

By transmitting brain signals to different regions of the body, the nervous system establishes the connection between ideas and acts.

The topmost layer of the skin on human body is called the epidermis. It defends your body from damage, keeps you hydrated, regenerates skin cells, and includes melanin, which gives your skin its colour.

The epidermis is the exterior layer of cells that covers an organism, specifically the surface mucosa of an animal's skin. It is also the outermost layer of tissue of a plant, with the exception of places where periderm takes its place. 1) The epithelia shield the cells underneath them.

Answer:

Cells in an organism that lack contact inhibition are likely to continue replicating uncontrollably and form a mass of tissue known as a tumor. This uncontrolled cell growth can lead to the development of cancer if the cells become abnormal and continue dividing even when they should stop. Normal cells, on the other hand, have a contact inhibition mechanism that prevents them from replicating when other cells are in close proximity, helping to regulate the growth and division of cells in the body.

The process of protein expression begins with the transcription of genetic information from DNA to RNA, followed by the translation of RNA into a protein.So option b is correct.

Transcription is the first step in protein expression, during which the genetic information encoded in a DNA sequence is transcribed into RNA. This process is carried out by RNA polymerase enzymes, which bind to the DNA template strand and synthesize a complementary RNA molecule that carries the genetic information for the protein being expressed. The RNA molecule produced during transcription is known as messenger RNA (mRNA), and it serves as a template for the next step in protein expression, which is translation.

Translation is the process by which the genetic information contained in mRNA is translated into a sequence of amino acids, the building blocks of proteins. This process occurs on ribosomes, which read the codons on the mRNA and use this information to select the appropriate amino acids and link them together to form a protein chain.

Adenosine triphosphate (ATP), an energy-rich compound that absorbs the chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes, is one goal of the degradation of foodstuffs.

ATP is created when the energy contained in chemical bonds is converted from one form to another. The chemical energy contained in food molecules is captured and then released to power the work being done by the cell. Consider ATP as the universal currency of your body's cells. Your body breaks down the food you eat into tiny macronutrient components. Your body converts all the carbs in your food to glucose, a simple sugar. A series of chemical processes known as cellular respiration convert glucose into ATP, which can then be used as energy to fuel many reactions throughout the body.

If you had extracted DNA from animal cells instead of plant cells then cell walls will be different among them. Plant and animal cells have a cell membrane that bacterial cells do not.

Plant cell walls frequently contain other polymers like lignin, suberin, or cutin that are incorporated or anchored there. Land plants lack the glycoprotein-containing polysaccharides like carrageenan and agar that are present in the cell walls of algae. Bacterial cell walls are composed of peptidoglycan. Polysaccharides, pseudo peptidoglycan, and glycoprotein S-layers are just a few of the compounds that can be found in the cell walls of archaea. Fungi's cell walls are made of N-acetylglucosamine polymer chitin. Because their cell walls are comprised of biogenic silica, diatoms are exceptional in this regard. A cell wall is an external structural layer that is present in several cell types. It offers security, a filtering system, and structural support to the cell. Many eukaryotes, including mammals, lack cell walls, in contrast to the majority of prokaryotes and some eukaryotes, including plants, algae, and some animals (except mollicute bacteria).

Each myofibril consists of repeating units called sarcomeres, which are the functional units of skeletal muscle tissue.

Sarcomeres are made up of two types of protein filaments: thick filaments and thin filaments. The thick filaments are composed mainly of myosin, a motor protein that interacts with the thin filaments to generate muscle contractions. The thin filaments are made up of actin, tropomyosin, and troponin, which regulate the interaction between myosin and actin.

The arrangement of the thick and thin filaments within the sarcomere gives skeletal muscle its characteristic striated appearance. The thick filaments are located in the center of the sarcomere, while the thin filaments are attached to the Z-discs at the ends of the sarcomere.

When the muscle contracts, the myosin heads on the thick filaments bind to the actin on the thin filaments, pulling them towards the center of the sarcomere and causing the muscle to shorten. This process is known as the sliding filament theory, and it is the basis for all muscle contractions.

One hypothesis to explain why methylated CpG dinucleotides are hotspots for point mutations in human DNA is that the methylation process itself, or the enzymes involved in maintaining DNA methylation, could introduce errors during replication or repair.

Methylation of cytosine in CpG dinucleotides is a common epigenetic modification that plays a role in gene regulation and silencing. However, the addition of a methyl group to cytosine can also affect the stability of the DNA molecule, making it more prone to damage and errors during replication and repair. In addition, the enzymes that maintain DNA methylation patterns can also introduce errors, especially when they encounter a methylated CpG site. For example, DNA methyltransferases may make errors during replication or repair, leading to mutations in the DNA sequence. Moreover, the presence of a methyl group at a CpG site can also affect the recognition and repair of damaged DNA. The DNA repair machinery may be less efficient or more error-prone when it encounters a methylated CpG site, leading to an increased risk of mutations. Therefore, one hypothesis is that the methylation of CpG dinucleotides may increase the likelihood of errors during replication and repair, leading to an increased frequency of point mutations in the human genome. Further research is needed to fully understand the mechanisms underlying the association between DNA methylation and point mutations.
