The 2 basic steps of polypeptide synthesis are:
- Transcription - the synthesis of mRNA from a DNA template. Only one strand of DNA is copied, and a single gene may be transcribed thousands of times.
- Translation - the process where ribosomes synthesize proteins using the mature mRNA transcript produced during transcription. The ribosome attaches to mRNA, and then moves along the mRNA adding amino acids to the growing polypeptide chain.

How many steps are there in protein synthesis?
Protein synthesis involves two main steps: transcription, where the information in DNA is copied into messenger RNA (mRNA) in the nucleus; and translation, where the mRNA is used as a template to assemble amino acids into a protein at ribosomes in the cytoplasm. Each step consists of multiple sub-steps involving different molecules and enzymes.
What is the smallest structure between dipeptide amino acid polypeptide and protein?
The smallest structure among dipeptide, amino acid, polypeptide, and protein is the amino acid. Here’s a quick breakdown: Amino acid Amino Acid: The basic building block of proteins. Dipeptide: Formed by two amino acids linked together. Polypeptide: A longer chain of amino acids. Protein Protein Protein: One or more polypeptides folded into a functional form12
Which describes the flow of information in protein synthesis?
The correct molecular involved in protein synthesis is DNA, messenger RNA, transfer RNA, and polypeptide. When a DNA is read, it produces a messenger RNA, amino acids are then matched with codons (transfer RNA) forming chains of polypeptides.
How many polypeptide chains form the globin portion of the molecule?
4 polypeptide chains, each bound to a heme group to form hemoglobing
Give an example of polypeptide?
Insulin is an example of a polypeptide. It is a hormone made up of two polypeptide chains, A and B, linked by disulfide bonds. Insulin plays a crucial role in regulating blood sugar levels in the body.
What are the basic steps in making a protein?
Protein synthesis involves two steps: transcription and translation. In transcription, DNA makes mRNA, which travels to the ribosome. In translation, the ribosome reads the mRNA and assembles amino acids into a protein chain.
What is the name of the process of building up large proteins in a cell?
Protein synthesis requires two steps: transcription and translationMessenger RNA (mRNA) a copy of a portion of the DNA. It carries genetic information from the gene (DNA) out of the nucleus, into the cytoplasm of the cell where it is translated to produce protein. Proteins are created by ribosomes translating mRNA into polypeptide chains. These polypeptide chains undergo PTM (Posttranslational modification) to give the mature protein.

What are the reactions both directional?
Two new tandem reactions for the synthesis of 3,5-disubstituted pyrrolizidines and the first total synthesis of alkaloidcis-223B (in 7 steps and 43% overall yield).
What are the two kinds of RNA?
mRNA- messenger RNA and type of RNA that is used in protein synthesis. It carries a copy of the instructions for assembling amino acids (which was taken from the original DNA).(source for mRNA) What_is_mRNAAtRNA- transport amino acids to ribosomes for incorporation into a polypeptide undergoing synthesis.(source for tRNA) transfer-rna
What two basic steps must be performed in any biometric technology process?
enrollment, matching
Where does peptide bond occur in protein synthesis?
A peptide bond forms between the carboxyl group of one amino acid and the amino group of another amino acid during the process of protein synthesis in the ribosome. This bond is formed through a dehydration synthesis reaction, resulting in the formation of a polypeptide chain.
What are the two basic steps to begin career planning?
The first step is to identify what your career will be. The next step is to identify the steps that will take you closer to your goals of launching your career.
What are the two sites of lipoprotein synthesis?
The small intestine and the liver are the two sites of lipoprotein synthesis.
