Each base pair forms a "rung of the DNA ladder" by joining two complementary DNA nucleotide bases. Two linked strands of DNA form a double helix, which is a structure that resembles a twisted ladder.
What is complementary base pairing in DNA molecule?Because they are complementary base pairs, adenine binds to thymine while guanine attaches to cytosine. The complimentary bases may unite to form a bond.
This aids in holding the DNA molecule's two antiparallel strands together to form the helix. The complimentary base pairing rule refers to this.
Cytosine pairs with guanine, while adenine pairs with thymine. The two strands are so complimentary to one another.
For instance, a complementary DNA strand will have the nucleotide sequence 5' CTAGCTAG 3' for a DNA strand with the nucleotide sequence 3' GATCGATC 5'.
Therefore, According to this rule, nucleotides A and T and bases G and C are always equally abundant in DNA.

The diffusion of water molecules a secectively permeable membrane.
What is Diffusion?The net passive movement of molecules or particles from areas of higher concentration to areas of lower concentration is known as diffusion. There needs to be a concentration gradient for diffusion to happen.
The dissimilarity in the quantity of solutes, particles, or molecules between the two locations will drive them to travel between the two regions.
The gradient created by the uneven particle concentration between two fluids will cause the particles to move in order to balance the discrepancy in concentrations. However, solutes do not migrate in a single direction during the diffusion process.
Therefore, The diffusion of water molecules a selectively permeable membrane.

List the following structures from largest to smallest: proton pump, nuclear pore, cyt c ribosome,
nucleus.
Answer:
Nucleus
Nuclear pore
Proton pump
Cyt C Ribosome
Explanation:
The nucleus of the cell is the largest of all of these structures, all of the others are located inside the nucleus of the cell or interact with it, the nuclear pore is a pore in the nucleus that allows the transport of proteins through the membrane, the proton pump passes through the nuclear pore, and a Ribosome is a protein that transports nutrients, so that would be the smallest.
The order from largest to smallest is nucleous>> >> ribosome >> nuclear pore >> proton pump >> Cyt C.
The nucleus is the organelle that contains the genetic material in a eukaryotic cell, whereas ribosomes are protein factories.The nuclear pore is a structure that allows the passage of certain molecules between the cytoplasm and the nucleus.The proton pump is an integral protein-membrane, whereas Cyt C is a mitochondrial protein.In conclusion, the order from largest to smallest is nucleous>> >> ribosome >> nuclear pore >> proton pump >> Cyt C.

Explain why the steroid hormone estradiol (MW 272) readily crosses membranes by simple diffusion but the much smaller H requires transport proteins
Answer:
Estradiol has a higher partition coefficient than H+ ions
Explanation
Estradiol is a non-polar and hydrophobic molecule that has a higher partition coefficient than H+ ions, it means that the cell membrane is more permeable to this molecule because it can dissolve in and diffuse within the hydrophobic phase of the membrane. The movement of polar charged molecules (even small H+ ions) requires the input of energy to be able to dissolve within the lipid bilayer. In consequence, the movement of H+ ions requires proteins capable of transporting these protons through the membrane.

How big of an advantage does a variant of a gene have to give to start becoming more common in a population?
1. Greater than 0%
2. Greater than 5%
3. Double
Answer:
The correct answer is 1. Greater than 0%. An allele to become common must have a frequency of at least 0.005%
Explanation:
A polymorphic gene has more than two alleles. The more alleles there are in a population, the more polymorphic the gene is.
In a polymorphic gene, the allelic frequency of the most common allele must be minor of 99%, while the less common allele must have an allelic frequency superior to 0.005%. If any allele does not reach this frequency in the population, it is not considered to be common. In fact, it is considered to be a rare allele.

10. What changes during a chemical reaction between two compounds?
A. number of atoms
B. chemical bonds
C. total mass
D. total energy
Answer:
I think it's chemical bonds I'm not of that helped
The changes occurs in chemical bond during a chemical reaction between two compounds. The correct option is B.
What is chemical bond?A chemical bond is a long-lasting point of attraction among atoms, ions, or molecules which then allows chemical compounds to form.
Ionic bonds are formed by the electrostatic force between oppositely charged ions, whereas covalent bonds are formed by the sharing of electrons.
A covalent bond is the strongest bond in chemistry. In such bonding, each atom shares electrons that bind them together.
The bonds that hold molecules together break apart and form new bonds during chemical reactions, rearranging atoms into different substances.
Each bond requires a different amount of energy to break or form; without this energy, the reaction cannot occur, and the reactants remain unchanged.
Thus, the correct option is B.

You are performing an experiment with Primase, using a specific DNA template. In this experiment, you provide NTPs (ATP, UTP, CTP, GTP) which contained only one radioactive phosphate group, in the alpha-phosphate position (the alpha- phosphate is the one attached to the sugar. the other phosphates are beta and gamma). After RNA synthesis occurs, you separate the resultant RNA strand any of the NTPs that have not been incorporated into the RNA, and measure the radioactivity of the newly synthesized RNA.A) In this experiment, would you expect the newly synthesized RNA be radioactive? Explain why.B) If you forgot to add CTP when you did the experiment, would the resulting RNA be radioactive?C) If you did the experiment, with all the NTPs provided, but only the beta phosphate was radioactive for each of the NTPs, would radioactivity be found in the RNA? Explain why.D) If you did the experiment, with all the required NTPs, but only the ATP was radiolabelled Would radioactivity be found in the RNA? Explain why.
Answer:
(a). Yes.
(b). RNA becomes Radioactive.
(c). No.
(d). It depends. If the gamma phosphate and beta phosphate are not labeled, then the RNA will have certain degree of radioactivity.
Explanation:
So, let us do right into the explanation behind the answers to the questions asked.
(a). The answer to this part of the question is "Yes" because in creating or in the formation of the glycosidic bond, all the alpha phosphate group were taken into consideration that is they were all used, thus making the newly synthesized RNA to be radioactive.
(b). The RNA becomes Radioactive is the answer to this part of this question because CTP is needed in the experiment.
(c). The answer to this part (c) of this question is ''No'' because the only thing that takes part in bonding is the alpha phosphate.
(d). It depends. If the gamma phosphate and beta phosphate are not labeled, then the RNA will have certain degree of radioactivity.

What is the protozoan and who is the first to observe one?
Answer:
Protozoa is an informal term for a group of single-celled eukaryotes, either free-living or parasitic, which feed on organic matter such as other microorganisms or organic tissues and debris. Anton van Leeuwenhoek was the first person to see protozoa, using microscopes he constructed with simple lenses. Between 1674 and 1716, he described, in addition to free-living protozoa, several parasitic species from animals, and Giardia lamblia from his own stools.
