The correct answer is telomerase protects the ends of chromosomes from nucleases and helps in maintaining the integrity of linear chromosomes.
What is telomerase?
It is an enzyme present in eukaryotes that repairs the telomeres of the chromosome so that they do not become progressively shorter during chromosome replication.
It is the enzyme responsible for the addition of guanine-rich repetitive sequences. Its activity is exhibited in gametes and stem and tumor cells.
Telomerase protects the ends of chromosomes by binding at an RNA molecule that contains a sequence complementary to the telomeric repeat.
Let us discuss other statements:
Without the replication of telomeres, it becomes too short and chromosomes reach a critical length and can no longer be replicated so the cell dies.Telomeres are found at the ends of the chromosome of only eukaryotic organisms.Telomeres are composed of repetitive sequences of six base pairs, TTAGG. With each cell division, some of the telomeres are lost. But the number of times that mostly dividing cells can divide is limited.Hence telomeres protect the ends of chromosomes from becoming frayed or tangled by adding repeats to the end of the chromosome.

Duchenne muscular dystrophy remains in the population because the allele is , and carrier mothers pass it to carrier daughters.
Answer: X-linked Recessive
Explanation:
Duchenne muscular dystrophy is a disease caused by a genetic mutation of the X-chromosome and is recessive.
Duchenne muscular dystrophy is a disease caused by a genetic mutation of the X-chromosome and is recessive.
What are the séx-linked genes?These are genes that can be found only in the X-chromosome. The inheritance pattern expressed by these genes varies from the one expressed by genes located in autosomal chromosomes.
In the exposed example,

Question 4 of 25 These images show models of a sugar molecule made during photosynthesis and an amino acid molecule. How could the models be used to support the idea that the amino acid molecule contains carbon atoms from sugar molecules made by photosynthesis? © A. Both molecules contain a chain of carbon atoms. © B. The molecules have similar shapes. O C. The molecules contain all the same types of atoms. © D. Both molecules contain stored chemical energy.
The models can support the idea that the amino acid molecule contains carbon atoms from sugar molecules made by photosynthesis because both molecules contain a chain of carbon atoms. So the correct option is A. Both molecules contain a chain of carbon atoms.
What is photosynthesis?Photosynthesis is a process in which inorganic matter is converted into organic matter by the energy provided by sunlight. Glucose molecules are then created from carbon dioxide and oxygen is released. This process occurs in photoautotrophic beings, that is, they produce their own food and do not need to obtain it from external sources but can be transformed from light.
The amino acids in plants are going to be formed by amination and transamination processes, it requires certain bases to be able to form as pre-existing amino acids or the components that it will need for its formation, provided by molecules within the cells
Therefore, we can confirm that the correct option is A. Both molecules contain a chain of carbon atoms.

If a RNA virus with radioactive sulfur was allowed to infect non-radioactive bacteria and replicate then in the centrifugation process, the highest radioactivity would be found in the protein coat of the virus which is present in the supernatant.
RNA is the abbreviation for Ribonucleic acid. It is the unstable type of nucleic acid generally present in some viruses and bacteria. There are three main forms of RNA: m-RNA, r-RNA and t-RNA.
Radioactivity is the presence of some radioactive element in any biological molecule that emits radiation spontaneously. Since DNA does not contain any sulfur, therefore the virus can contain radioactivity only in the protein coat. Sulfur is an essential part of cell membranes.

you have an enzyme solution and you add an inhibitor molecule and observe a marked decrease in enzyme activity. you increase the substrate concentration but this does not lead to any observable increase in enzyme activity. what can you conclude about your inhibitor?
Non-competitive inhibitor, does not cause an increase in enzyme activity when the concentration of the substrate is increased.
Noncompetitive inhibition is a special sort of allosteric regulation that occurs when an inhibitor binds to an allosteric site, reducing the enzyme's effectiveness.
Simply put, an allosteric site is one that differs from the substrate-binding active site. Comparable to competitive, uncompetitive, and mixed-type inhibition, noncompetitive inhibition is distinct from the others.
The inhibitor shares the same affinity for both the enzyme and the enzyme-substrate complex in noncompetitive inhibition because it binds at the allosteric site independently of substrate binding.
Noncompetitive inhibition is distinguished from uncompetitive inhibition by this activity, in which an inhibitor only binds to the enzyme-substrate complex.
The reaction rate won't change even if the substrate concentration is increased, and enzyme activity will still be suppressed.

Answer:
Since you did not provide the specific molecules, here are some ways that glucose is used for synthesis:
Protein molecules - Glucose regulates protein synthesis through AMPK (Activated Protein Kinase) pathways. AMPK is activated by cellular energy via changes in AMP levels resulting from energy.
Gluconeogenesis Pathway - The process where glucose is synthesized using pyruvate and lactate precursors from non-carbohydrate metabolites, amino acids, and glycerol (derived mainly from metabolized fat).
Fatty Acids - Metabolized into pyruvate using glycolysis in the cytoplasm, oxidized pyruvate generates ATP in the mitochondria. During the fed state the glycolytic products synthesize fatty acids through lipogenesis.
Amino Acids & Lipids - Through photosynthesis in plants, glucose joins with nitrates in the soil to create amino acids. The amino acids combine during protein synthesis and glucose is converted to lipids within the plant seeds.
