Describe the structure and parts of DNA molecule

Answers

Answer 1

Answer:

The DNA molecule consists of two strands that wind around one another to form a shape known as a double helix. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), and thymine (T).

where does reduction occur in an electrolytic cell

Answers

Answer:  The Cathode

Explanation:

Reduction always occurs at the cathode, and oxidation always occurs at the anode. Since reduction is the addition of electrons, electrons must travel toward the site of reduction. In an electrolytic cell the negative charge is on the cathode, while the positive charge is on the anode.

Answers

Answer:

Chromosomes are tightly packed DNA and proteins. The DNA and proteins take on a tightly coiled structure within the chromosome. The chromosomes are then kept inside the nucleus. Their role is to carry basic genetic material. This provides the cell with genetic information that's used to carry out different cellular functions. These functions include survival, growth, and the ability to reproduce.

In the citric acid cycle, the enzyme succinate dehydrogenase catalyzes a reversible reaction using FAD/FADH2 as an oxidizing/reducing agent. Which of the following statements best explains how the redox component of this reaction contributes to the reaction's ability to be reversible under cellular conditions?
A. FAD has no reduction potential when it is enzyme-bound.
B. FAD can be reduced by the sequential addition of one hydrogen at a time.
C. FAD/FADH2 is covalently bound to succinate dehydrogenase.
D. The change in the biochemical standard reduction potential is small.

Answers

The statement which best explains how the redox component of this reaction contributes to the reaction's ability to be reversible under cellular conditions is; Choice D: The change in the biochemical standard reduction potential is small.

Discussion:

A reversible process is one in which the system and environment can be restored to exactly the same initial states that they were in prior to when the process occurred, if we go backward along the path of the process.

However, the necessary condition for a reversible process is therefore the quasi-static requirement.

The quasi-static requirement in this case is that the change in the biochemical standard reduction potential is small.

DNA is a polymer composed of different nucleotides joined by their extremes.

Nucleotides are monomers composed of a sugar molecule, joined with a phosphate group and a nitrogenated base.

Nitrogenated Bases

Nitrogenated bases are molecules carrying nitrogen and exhibiting the chemical properties of a base.

Nitrogenated bases are purines and pyrimidines. Adenine and guanine derive from purines, while Thymine and Cytosine derive from Pyrimidines.

Adenine pairs with thymine, while guanine pairs with cytosine.

Answers

Some fossil snakes have remnants of hip bones and legs even though these animals had no legs. These remnant structures are best described as: vestigial structures.

Vestigial structures are organic structures that do not appear to fulfill any important biological function in the organism that possesses them.

These structures are preserved as an inheritance of the evolutionary process, because at some point in the history of evolution an ancestor of the current species had that structure.

These types of structures, which can be bones, organs, structures in the skin or any other part of the body, no longer offer any meaningful function for the body.

The presence of vestigial structures in animals is considered proof that evolution and natural selection exists.

Therefore, we can conclude that some fossil snakes have remnants of hip bones and legs even though these animals had no legs. These remnant structures are best described as vestigial structures.
