Which statement best describes the relationship between proteins and nucleic acids? Proteins read the instructions that are contained in nucleic acids. Nucleic acids synthesize the amino acids for protein construction. Nucleic acids provide the blueprint for the construction of proteins. Proteins are composed of nucleic acids..

Answers

The nucleic acids provide blueprints for the construction of proteins. The mRNA (messenger RNA) takes the genetic info of the proteins from the DNA ( Deoxyribonucleic acid) and it give it to the ribosome (which produces proteins) so the ribosome produces protein according to the 'blueprints' that came from the DNA

Nucleic acids provide the blueprint for the construction of proteins, the third statement best describe the relationship between proteins and nucleic acids.

The primary information-carrying molecules in the cell are Nucleic acids. Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are the two main forms of nucleic acids. DNA is the genetic substance of all free-living creatures and the majority of viruses. RNA is the genetic material of certain viruses, but it is also found in all living cells, where it plays a crucial part in activities such as proteinsynthesis.

The mRNA (messenger RNA) receives the genetic information of the proteins from the DNA (Deoxyribonucleic acid) and gives it to the ribosome (which generates proteins), so that the ribosome may produce proteins based on the 'blueprints' that came from the DNA.

Thus, the third statement best describes the relationship between proteins and nucleic acids.

Which one of the following choices is the first part of the small intestine?a. Duodenum
b. Macrodenum
c. Jejunum
d. Ileum

Answers

Answer: The correct answer is A) Duodenum.

Small intestine is the part of GI ( gastrointestinal tract) that is located between stomach and large intestine. It is the site of final digestion of food and absorption of maximum nutrients and minerals.

It is primarily divided into three parts, which are Duodenum, jejunum, and ileum.

Duodenum forms the first region of the small intestine, which is shortest in size and is the site of preparation for absorption of nutrients. It receives pancreatic juice and bile, which perform final digestion of food.
a. Duodenum The parts of the small intestine are in this order: Duodenum Jejunum Ileum
