How are proteins and nucleic acids related?
a.) they both provide energy.
b.) they both carry genetic information.
c.) the structure of proteins is determined by nucleic acids.
d.) the subunits of nucleic acids are also the subunits of proteins.

I believe the correct answer is C.) The structure of proteins is determined by nucleic acids.

To understand this answer, we have to go back to a process called protein synthesis which occurs in the ribosome of a cell. To make the proteins, transcription of DNA to mRNA first occurs in the nucleus. A process called translation then occurs which is just reading the mRNA to understand the message it contains. mRNA is usually single stranded and has bases that code for specific amino acids that build up proteins. Making the mRNA from DNA is the first phase of DNA synthesis called transcription. A strand of mRNA is created and complements the strand of DNA. For Example, if the DNA coding was GAC ACT GAC, the complementary mRNA will be CUG UGA CUG. C complements for G, U complements for A and G complements for C. UAGCT are nitrogenous bases or the nucleic acids found in RNA and DNA. Transcription is divided into initiation where an enzyme called RNA polymerase binds to the promoter region signaling the DNA to unwind to enable the enzyme RNA polymerase to read of the 2 strands that make the DNA. Elongation is the second step where nucleotides are added the strand of mRNA with the complementary bases. Termination is the last step and the mRNA strand that complements the DNA is fully completes so it cuts away from the DNA. Translation of the mRNA then occurs so that a protein can be made. The mRNA leaves the nucleus and enters into the ribosome that reads the codons in the mRNA and molecules of tRNA carry amino acids into the ribosome according to how the codons of mRNA are arranged. In end, when the ribosomes translate to the terminating codon, the process of translation ends and a protein is made with amino acids arranged in the correct sequence.

Option (C) The structure of protein isdetermined by nucleic acids is correct answer.

Further Explanation:

The protein is an elongated chain of amino acids that are a necessary part of all living organisms. Protein is the basic structural element of body tissues such as muscles, hair, etc. nucleic acids are macromolecules that store genetic data and modify protein production. Proteins are classified as primary, secondary, tertiary and quaternary proteins according to the types of bonds present in the structure as well as its complexity.

Deoxyribonucleicacid and ribonucleicacid are the nucleic acids composed of nucleotides. The DNA present within the cell's nucleus transcribes itself to make RNA and the RNA translates to make a protein. Carbohydrates are the primary supply of energy within the body. Nucleic acids are nowhere involved in providing energy to the body. The nucleic acids (RNA and DNA) carry the genetic data in an organism. The nucleic acids are made up of nucleotides thymine, adenine, cytosine, uracil, and guanine. Twenty amino acids randomly made up the protein. Some examples of amino acids are alanine, glycine, proline, glutamine, tyrosine, etc. So, the subunits of nucleic acids don't seem to be the subunits of proteins.

Thus, the nucleic acids determine the structure of proteins formed.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

"menstrual cycle is a complex cycle that consists of several processes. order of occurrence of steps in menstrual cycle are as follows:

1. high progesterone levels maintain the endometrium lining of the uterus.

2. endometrium lining breaks down and low levels of estrogen stimulate the pituitary to release fsh and lh.

3. fsh and lh stimulates the follicles to develop and the oocyte to produce estrogen.

4. rising estrogen levels suppress fsh production and development of other follicles.

5. a spike in lh causes follicle to rupture.

6. a breakdown of corpus luteum causes progesterone level to drop."
