How is protein made from a strand of DNA?

Answer 1

There are 2 parts to the process of creating protein from DNA:

* Transcription

- where the [four possible] base sequences in DNA are read as' three-at-a-time' triplet codons, thereby forming messenger RNA (mRNA). These strands of mRNA are processed [ namely by the removal of introns ][ exons are expressed ] and then exit the nucleus, via nuclear pores {that, by the way, have the ability to disintegrate and reintegrate upon signals - along with the nuclear envelope itself - } and are then sent to the awaiting Ribosomes - on the cytoplasmic side of the ER; {the intra-endoplasmic-reticular space is contiguous throughout the ER and is a Transport Highway for nascent proteins to the cell's extremities; and,

* Translation

- mRNA leaves the nucleus and goes to the structures called ribosomes in the cytoplasmic reticulum. The message that the mRNA contains is translated, and a PROTEIN is built up, bit by bit, from its individual amino-acid {generally one codon per a-a} subunits.

Answer 2

Proteins are made from a strand of DNA through the process of transcription and translation. During transcription, the DNA is first copied into a messenger RNA (mRNA) molecule. This mRNA molecule then carries the genetic information to the ribosomes, where translation occurs and the sequence of nucleotides in the mRNA is decoded into a sequence of amino acids, forming a protein.

Answer 3

The DNA is first unwound and unziped by several enzymes. Then a piece of Rna is created to match the DNA. It is created much like DNA with A connecting with T, C to G, and G to T. However, instead of using T, U is used. The Rna is then moved out of the nucleus through a nucleur pore. Transport Rna move it to a ribosome. There, transport Rna molecules with codons on one end and Ameno acids on the other join to the ribosome. A codon is a group of three bases, like A,U, C, or G. Amino Acids are the building blocks of DNA. Every Amino Acid has two to four codons that code for it. When one codon on the tRna molicules matches up with the corosponding codon on the Rna molicule, it stickes the Amino acid on to the chain of Ameno acids which are being stuck on.. Once all of the amino acids have been stuck together, the chain is sent to the Golgi body for folding into a protein.

Answer 4

The DNA template is merely used as what the name implies, as a template. Once the mRNA is formed using the template, it moves to the ribosome where protein synthesis can occur.
