What stores the genetic information in DNA Mcq?

13. What stores the genetic information in DNA? Explanation: Genetic information is stored in the sequence of nitrogenous base as they are of four types and they are A, T, G and C. The order of their occurrence decides the mRNA sequence which in turn codes amino acids and leading to synthesis of proteins.

What macromolecule stores genetic information?

Nucleic acids are polymers that store, transmit, and express hereditary (genetic) information. This information is encoded in the sequences of monomers that make up nucleic acids. There are two types of nucleic acids: DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).

How the structure of DNA allows it to store the information that is used to produce proteins in the cell?

DNA’s unique structure enables the molecule to copy itself during cell division. … This template strand is then transcribed into mRNA, which is a molecule that conveys vital instructions to the cell’s protein-making machinery.

Does the nucleus store genetic information?

The nucleus is a membrane-enclosed organelle, found in most eukaryotic cells, which stores the genetic material (DNA).

How is genetic information stored and inherited?

Chromosomes are contained inside the cell’s nucleus . These are long, thin, threadlike structures made from molecules of DNA that store genetic information. Chromosomes are found in the nucleus of body cells in pairs – one chromosome is inherited from the mother and one is inherited from the father.

What is the structure of DNA called?

double helix

Nucleotides are arranged in two long strands that form a spiral called a double helix. The structure of the double helix is somewhat like a ladder, with the base pairs forming the ladder’s rungs and the sugar and phosphate molecules forming the vertical sidepieces of the ladder.Jan 19, 2021

Why does DNA store genetic information?

With the exception of certain viruses, DNA rather than RNA carries the hereditary genetic code in all biological life on Earth. DNA is both more resilient and more easily repaired than RNA. As a result, DNA serves as a more stable carrier of the genetic information that is essential to survival and reproduction.

What is the true structure of DNA Mcq?

The primary structure of DNA:- DNA is a long, thread like macromolecule and is made up of large no.deoxyribonucleotide. Each deoxyribonucleotide is composed of a nitrogenous base, sugar and a phosphate group. The nitrogenous bases in DNA are adenine, guanine, thymine and cytosine.

In what structure does translation occur?

the ribosome Translation occurs in a structure called the ribosome, which is a factory for the synthesis of proteins. The ribosome has a small and a large subunit and is a complex molecule composed of several ribosomal RNA molecules and a number of proteins.

Which macromolecule holds your genetic information and manufactures proteins?

DNA DNA stores hereditary information which provides instructions for the assembly of proteins.

How does the structure of DNA encode genetic information quizlet?

Genetic information is encoded as the sequence of nucleotides in a DNA molecule. … Then DNA polymerase binds to each parental DNA strand. Free nucleotides form hydrogen bonds with complementary bases on teh parental strands, and DNA polymerase links the free nucleotides to form new DNA strands.

How is the structure of DNA organized what is the biological significance of DNA?

Robert and his team study chromatin, the structure composed of DNA and proteins that makes up chromosomes. Its main role is to package DNA molecules containing all the organism’s genes into the cell nucleus, which is approximately 20,000 times smaller than the DNA itself.

How does the structure of DNA determine the structure and function of a protein?

DNA carries the genetic information for making proteins. … The base sequence determines amino acid sequence in protein. Messenger RNA (mRNA) is a molecule which carries a copy of the code from the DNA, in the nucleus, to a ribosome, where the protein is assembled from amino acids.

What does Golgi apparatus do?

A Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell.
