∙ 15y agoDNA is made up of two strands, the sense strand and the antisense strand. the sense strand contains the code for the protein so to get that code, the antisense strand is copied. the DNA is unzipped with the enzyme helicase and the antisense strand of the gene is copied with free nucleotides. They are then joined together with the enzyme polymerase and ligase to form an mRNA strand which leaves the nucleus. This mRNA strand joins to the small subunit of a ribosme and then the large subunit is attached. Amino acids are attached to the amino accid binding site of the tRNA molecules by enzymes. the first amino acid moves into the A- site of the large subunit of the ribosome and the three bases which make up the anticodon form complementary base pairs with the codon of the mRNA. In the p-site the next tRNA molecule which is bonded to an amino acid forms complemtary base pairs with the next codon of the mRNA which is exposed by the p-site. The amino acids join together and the tRNA which is attaced now to bothe amino acids moves to the p-site and the tRNA that was in the p-site leaves the ribosome. This continues until the polypeptide chain is completed i.e when the ribosome reaches the end of the mRNA strand. The polypeptide chain moves into the endoplasmic reticulum and then the Golgi apparatus where it is folded and organised into forming proteins which leave the cell in lysosomes.

Howdy there!
The process of producing an mRNA from DNA is called transcription. And the process of reading the mRNA to get proteins is called translation, in case you wanted to know.
This should definitely help you! 😄

∙ 15y agoGenes are coded for in DNA. In eukaryotic cells a 'copy' of the information on the DNA is made in the cell nucleus by a process known as transcription, this is mRNA (messenger RNA). The mRNA exits the nucleus and travels to the ribosomes where it attaches to the ribosome complex (tRNA). The ribosome then 'reads' the mRNA and attaches 1 amino acid for every three bases. There is a start codon AUG which is where translation initiates, and a stop codon which is where it is terminated. There may be more than one three letter code for each amino acid, but only one protein for a three letter code. Eg: ATT, ATC and ATA all code for the amino acid Isoleucine, so there are 3 codes for one amino acid. ATA can code only for isoleucine, no other amino acid. A chain of amino acids is a protein.

∙ 13y agoIn translation, the mRNA that was produced by transcription of the DNA is decoded by the ribosome. This produces a specific amino acid chain, or polypeptide, that will later be folded into an active protein.

Does protein form RNA?
No, RNA is the cells' chemical messenger that carries instructions from DNA in the nucleus to the rest of the cell about when to make proteins and which ones. DNA makes RNA however the process does involve some enzymes that are proteins
. Ribosomes are made up of?
They are made up of RNA and proteins. mRNA refers to ribosomal RNA
What are ribosomes made up of?
Ribosomes are primarily responsible for biological synthesis of proteins. They are made up of ribosomal RNA and a variety of proteins. Edit : RNA & Proteins
What is translation and where does it occur in the cell?
It occurs in the nucleus of the cell. Translation refers to the process by which RNA is translated into proteins.
Process of making proteins is called?
naturally proteins are made by process called translation.. in translation the m-RNA produced by DNA is coded by ribosome and then a long polypeptide or chains of amino acid are formed which folds and forms proteins..!!!
What is the process that forms proteins such as hemoglobin?
It would be translation/transcription. Transcription= changing DNA to RNA; Tanslation= changing the RNA to proteins. The whole process is known as protein synthesis.
How is RNA molecule a script for the protein production process?
the DNA reads the rna making proteins
What does DNA and RNA ultimately construct?
DNA is transcribed into RNA which is translated into proteins. Only a small percentage of DNA and RNA become proteins. Some of the time the process stops after DNA is transcribed into RNA.
Are Ribosomes are made of one type of RNA and use other types of RNA in the process of making proteins?
Yes
Does protein form RNA?
No, RNA is the cells' chemical messenger that carries instructions from DNA in the nucleus to the rest of the cell about when to make proteins and which ones. DNA makes RNA however the process does involve some enzymes that are proteins
The process of assembling a protein form RNA is called?
This is Transcription, and it is called mRNA
What is the process of going from DNA to RNA called?
Transcription.During transcription the base sequence (genetic code) of part (a gene) of one strand of DNA is copied onto a strand of RNA as the RNA is synthesized.
What do proteins and ribosomes make?
tRNAThey are made up of proteins and rRNA. rRna are ribosomal RNA
Which proteins are made from RNA?
All proteins in the human body are made from RNA.
. Ribosomes are made up of?
They are made up of RNA and proteins. mRNA refers to ribosomal RNA
What are ribosomes made up of?
Ribosomes are primarily responsible for biological synthesis of proteins. They are made up of ribosomal RNA and a variety of proteins. Edit : RNA & Proteins
What is the purpous of RNA?
RNA is genetically very important . It has a nucleotide base as Uracil in place of thymine as found commonly in DNA. The RNA is very important when the process of transcription is followed by the process of translation where T-RNA codes for the anti-codon and thus it gives rise to the proteins.
