Answer: The correct answer is option C. To form RNA molecules from DNA molecule.

Explanation:

The main function of transcription is to form ribonucleic acid (RNA) molecules from deoxyribonucleic acid (DNA) molecule present in the nucleus. In transcription, small part of DNA is copied and attached to the RNA molecule with the help of enzymes i. e. RNA polymerase.

Answer:C. To from RNA molecules from DNA

Explanation: Transcription is the process of converting the genetic message in a DNA into a complementary RNA molecule. This process takes place in the nucleus and is catalyzed by an enzyme known as RNA polymerase. There are basically three classes of RNA that can be synthesized from a DNA molecule: transfer RNA (tRNA) which gets the corresponding amino acid from the cytosol and attaches it to the growing polypeptide chain; the messenger RNA (mRNA) which serves as a template for the synthesis of a protein molecule and ribosomal RNA (rRNA) which is a part of the ribosome. Ribosome is a cell organelle where proteins are synthesized.

What analogy can you create that compares to the structure of all four major macromolecules?
skad [1K]
Basically, macro molecules  fall into four classes;
The lipids
The carbohydrates
The proteins
The nucleic acids
 The fact that their role revolve around energy production by carbohydrates, energy storage and insulation by lipids, storage of genetic material by nucleic acids and structural support by proteins means this can be equated to the executive arm of the government that deals in provision of social amenity, protection,  creation of job opportunities and sustaining a country's culture.

How do cells release <br> Energy in the process of cellular respiration
White raven [17]

Answer:

Explanation:

There are two types of respiration:

1. Aerobic respiration  

2. Anaerobic respiration

Aerobic respiration

It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.

Glucose + oxygen → carbon dioxide + water + 38ATP

Anaerobic Respiration

It is the breakdown of glucose molecule in the absence of oxygen and produce small amount of energy. Alcohol or lactic acid and carbon dioxide are also produced as byproducts.  

Glucose→ lactic acid/alcohol + 2ATP + carbon dioxide

This process use respiratory electron transport chain as electron acceptor instead of oxygen. It is mostly occur in prokaryotes. Its main advantage is that it produce energy (ATP) very quickly as compared to aerobic respiration

What is the difference between genotype and phenotype
dlinn [17]

Answer:

  • person’s <u>genotype</u> is their unique sequence of DNA. More specifically, this term is used to refer to the two alleles a person has inherited for a particular gene. <u>Phenotype</u> is the detectable expression of this genotype – a patient’s clinical presentation.

Explanation:

person’s phenotype results from the interaction between their genotype and their environment.

The connection between genotype and phenotype is not always clear-cut. This means that you may encounter disparities between your patient’s genomic test result and their clinical presentation. Similarly, the phenotype of patients with a given genetic condition may vary greatly even within families.

Kaylis [27]
Gradual changes in the frequency of diseases over long periods are known as SECULAR TIME TRENDS. For example, the rate of mortality in USA due to coronary heart diseases over a period of time. Onset of puberty in girls is also a secular time trend.
Secular time trend is also referred as Secular Variation and Secular Drift.
