Adenine is the last nucleotide at the 3' end of one strand of DNA. It is base-paired with thymine on the other DNA strand. Which of the following statements about these nucleotides is FALSE? If the adenine has an unlinked 3' hydroxyl group, then the thymine must have an unlinked 5' phosphate group The adenine and the thymine are each bonded to the previous nucleotide in the strand by a phosphodiester bond The two nucleotides are located on DNA strands that are parallel to each other There are two hydrogen bonds between the adenine and thymine nitrogenous bases.

Answers

Answer 1

Answer:

The two nucleotides are located on DNA strands that are parallel to each other

Explanation:

Deoxyribonucleic acid, commonly known as DNA, is one of the two types of nucleic acids. It is a molecule composed of a nitrogenous base, pentose sugar and a phosphate group. According to the information given in this question, Adenine is the last nucleotide at the 3' end of one strand of DNA. The following are factual about the nucleotide;

- Since DNA is a double-stranded molecule, the Adenine nucleotide will be base-paired with Thymine nucleotide (complementary base pairing) on the other DNA strand.

- Since complementary DNA strands are opposite to one another, this means that if the adenine has an unlinked 3' hydroxyl group, then the thymine must have an unlinked 5' phosphate group.

- Nucleotides in a DNA strand are joined to one another via a covalent bond called PHOSPHODIESTER BOND. Hence, the adenine and the thymine are each bonded to the previous nucleotide in the strand by a phosphodiester bond.

- In the complementary base pairing between two nucleotide bases, there are two hydrogen bonds between the adenine and thymine nitrogenous bases i.e. A=T.

- DNA strands that make up a molecule are complementary and opposite to one another, hence, they are said to be ANTIPARALLEL.

Why is sexual reproduction associated with meiosis? meiosis reproduces identical DNA meiosis is the complete process of sexual reproduction meiosis helps to generate variability meiosis produces gametes

Answers

Answer:

meiosis produced gametes

Explanation:

During sexual reproduction, meiosis generates genetic variation in offspring because the process randomly shuffles genes across chromosomes and then randomly separates half of those chromosomes into each gamete. The two gametes then randomly fuse to form a new organism.

Please help! I will give brainiest answer!

Answers

Answer:

D

Explanation:

The vehicles have the same amount of kinetic energy because they are travelling at the same speed. There is a great difference in their masses but their speed is same. Kinetic energy of a body depends on both mass and velocity. If the mass of an object increases, its kinetic energy also increases and vice versa while on the other hand, if we doubles the speed of an object its kinetic energy increases four times so we can conclude that objects having same speed leads to same kinetic energy.

Phase 1 of the creation of life on earth was the formation of small molecules containing carbon and hydrogen. Phase 2 was the formation of self-replicating, information-containing molecules. Phase 3 was: Please choose the correct answer from the following choices, and then select the submit answer button. the development of a nucleus, enabling metabolism and creating the first cells. the formation of DNA. the development of a membrane, enabling metabolism and creating the first cells. the formation of RNA. the cooling of the earth to a temperature conducive to life.

Answers

Answer:

the development of a membrane, enabling metabolism and creating the first cells.

Explanation:

In Abiogenesis (evolutionary biology), the formation of life on earth is described by three (3) main stages and these includes; phase 1, phase 2 and phase 3.

In phase 1, small molecules that comprises of carbon and hydrogen are formed on earth. The second phase is the formation of molecules that can be replicated by themselves and contains informations.

Phase 3 involves the development of a membrane, enabling metabolism and creating the first cells.

A cell can be defined as the structural, fundamental, biological and functional unit of life. Cells are found in all living organisms because they are the basic unit of life.

Generally, cells have the ability to independently replicate themselves. These cells can be compared to the kind of structures found in a business or factory, where you have different workers performing different functions.

In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles such as nucleus, cytoplasm, cell membrane, golgi apparatus, mitochondria, lysosomes, ribosomes, chromosomes, endoplasmic reticulum, and vesicles.

The regular sequence of growth and division that cells undergo is called the cell cycle. This cycle makes it possible for the cells found in living organisms to divide and produce new cells.

Basically, there are four (4) phases of the cell cycle and these are;

I. Prophase.

II. Metaphase.

III. Anaphase.

IV. Telophase.

A teacher asks students to make a model of a transform plate boundary. The students use blocks to represent tectonic plates and slide the blocks past each other in the directions of the arrows as shown.

Answers

Answer:

The model is right.

Explanation:

The model made by the students about transform plate boundary is right because in the transform plate boundary, the tectonic plates moves horizontally by rubbing each other. As the tectonic plates rub against each other, huge stresses are created that can cause breaking the portions of the rock that results in earthquakes in that region. The area or regions where these breaking of rocks occur is known as faults. San Andreas Fault in California is the example of transform plate boundary.

In humans blood type A and B are equally dominant (codominant). Both types are dominant to type O. Aman with type AB blood marries a woman with type O blood, give the genotype and phenotype of all possible offsprings

Answers

Answer:

The correct answer would be -

Genotype: IAIO or IBIO

Phenotype: A Blood or B Blood

Explanation:

Blood group A and blood group B both are dominant over the blood group O, however, both A and B are codominant if present together and form the blood group AB.

The blood group of Aman is AB and If he marries the female with O blood group then possible blood group in offspring would be as follows:

gametes: Aman = IA and IB

woman = IO IO

then cross between:

    IA     IB

IO IAIO IBIO

IO IAIO IBIO

the genotype of this cross would be 50% chances of IAIO and 50% chances of IBIO and phenotype would be either Type A or type B.

What type of energy transformation takes place when a rose takes in energy from the soil and uses the energy to make its own food?​

Answers

Answer:

plants use photosynthesis to make food.

Explanation:

Photosynthesis takes place in the specific cells of plants known as chloroplasts, which are the cell type found in leaves. A single chloroplast is like a suitcase full of major photosynthesis materials. It has water-soaked from the root of the plant, atmospheric leaf absorbed carbon dioxide and chlorophyll in softened, labyrinthine organelles known as Thylakoids.

The true catalyst for photosynthesis is chlorophyll. This light-sensitive molecule is used to stimulate the process by cyanobacteria, plankton, and terrestrial plants.

The chlorophyll molecules are so awful for the green light to absorb that they reflect it like small mirrors that cause the majority of the leaves to look green. In the autumn we only look at these limitless colors of yellow and orange formed in carotenoid pigments after chlorophyll degradation.

Scientists have been studying four populations in a swamp area. In this area, alligators eat gar (a type of large fish), and both gar and diving ducks eat crabs. The data showed that recently the alligator population has decreased. How could the decrease in the alligator population affect the other populations? Be sure to explain whether the gar population, the diving duck population, and the crab population will change, and why.

Answers

Answer:

There wouldn't be enough resources for the alligator population to live off of thus decreasing its population number. This decrease affects the other populations because it without alligators, its predators and prey wouldn't gain its nutrition from it and it would overall change its environments' habitation. The gar population would increase because they wouldn't be eaten by the alligators and therefore increasing the diving duck population as well. The crab population would decrease because the gar (their prey) population increased which overcomes the number of crab in the population.
