Describe the relationship between DNA and proteins?

Answer 1

DNA is a polynucleotide which is the genetic material of all living cells. It is made up of units called nucleotides. Nucleotides of DNA are composed of a pentose sugar called deoxyribose, a nitrogen base and a phosphate group. Specific parts of DNA code for proteins. They are called genes.

Proteins are polymeric molecules which control all metabolic activities in the cell. They are made up of units called amino acids. Amino acids are molecules containing amino group and carboxylic group bonded to a tetravalent carbon atom.

Answer 2

An organ receives instructions to perform certain functions from the nucleus.

For example the heart receives the instruction to beat,the lungs receive instruction to breathe etc.

These instructions reside within the nucleus of each cell in the form of DNA. A DNA has step by step instructions to make a cell perform a certain function.

Relationship between DNA and protein

DNA strands give instructions to the cells to make certain type of molecules called proteins.

These protein molecules help cells to perform certain functions. Without the protein molecules a gene cannot function.

Answer 3

DNA is the genetic code that contains information for your body on how to make proteins. When making proteins, the mRNA (messenger ribonucleic acid) travels into the nucleus and copies a reflected code from the DNA. As it goes back into the cytoplasm and find the ribosomes, tRNA (transcription RNA) copies the codon from the mRNA and reflects it back to the original code on the DNA. This forms the anti-codon. As one codon and one anti-codon travels between the two subunits of the ribosome, an amino acid is formed. More amino acids chain up together, until the ribosome hits the stop codon--UGA. This amino acid chain is the protein that's made by the info given from the DNA.

Answer 4

The enzymes that copy DNA are made of protein. Also, DNA carries the code for protein synthesis, but since DNA cannot leave the cell the code is transferred to RNA and then brought to the ribosomes to synthesize specific proteins.

Answer 5

DNA is the instructions for making proteins through the medium of RNA.

DNA -> RNA -> proteins
