  • Protein Synthesis (Translation) – Microbiology: Canadian Edition

    This refers to the fact that DNA contains the information necessary for the cell to build one very important type of molecule: the protein. Most structural components of the cell are made up, at least in part, by proteins and virtually all the functions that a cell carries out are completed with the help of proteins. One of the most important classes of proteins is enzymes, which help speed up necessary biochemical reactions that take place inside the cell.

  • Translation – Concepts Of Biology – 1st Canadian Edition

    Some of these critical biochemical reactions include building larger molecules from smaller components such as what occurs during DNA replication or synthesis of microtubules and breaking down larger molecules into smaller components such as when harvesting chemical energy from nutrient molecules. Whatever the cellular process may be, it is almost sure to involve proteins. Protein synthesis begins with genes. A gene is a functional segment of DNA that provides the genetic information necessary to build a protein. Each particular gene provides the code necessary to construct a particular protein. Gene expression, which transforms the information coded in a gene to a final gene product, ultimately dictates the structure and function of a cell by determining which proteins are made. The interpretation of genes works in the following way. Recall that proteins are polymers, or chains, of many amino acid building blocks.

  • 132 Ribosomes And Protein Synthesis Answers

    The sequence of bases in a gene that is, its sequence of A, T, C, G nucleotides translates to an amino acid sequence. A triplet is a section of three DNA bases in a row that codes for a specific amino acid. Therefore, a gene, which is composed of multiple triplets in a unique sequence, provides the code to build an entire protein, with multiple amino acids in the proper sequence Figure 3. The mechanism by which cells turn the DNA code into a protein product is a two-step process, with an RNA molecule as the intermediate. Figure 3. From DNA to RNA: Transcription DNA is housed within the nucleus, and protein synthesis takes place in the cytoplasm, thus there must be some sort of intermediate messenger that leaves the nucleus and manages protein synthesis. There are several different types of RNA, each having different functions in the cell. Finally, instead of the base thymine, RNA contains the base uracil.

  • 9.6 Temperature And Microbial Growth

    This means that adenine will always pair up with uracil during the protein synthesis process. Gene expression begins with the process called transcription, which is the synthesis of a strand of mRNA that is complementary to the gene of interest. Transcription begins in a fashion somewhat like DNA replication, in that a region of DNA unwinds and the two strands separate, however, only that small portion of the DNA will be split apart.

    The triplets within the gene on this section of the DNA molecule are used as the template to transcribe the complementary strand of RNA Figure 3. A codon is a three-base sequence of mRNA, so-called because they directly encode amino acids. Like DNA replication, there are three stages to transcription: initiation, elongation, and termination. Stage 1: Initiation. A region at the beginning of the gene called a promoter—a particular sequence of nucleotides—triggers the start of transcription. Stage 2: Elongation. One strand, referred to as the coding strand, becomes the template with the genes to be coded.

  • Ribosomes And Protein Synthesis By Nicole Archer

    This process builds a strand of mRNA. Stage 3: Termination. The transcription process is regulated by a class of proteins called transcription factors, which bind to the gene sequence and either promote or inhibit their transcription. Before the mRNA molecule leaves the nucleus and proceeds to protein synthesis, it is modified in a number of ways. For this reason, it is often called a pre-mRNA at this stage. For example, your DNA, and thus complementary mRNA, contains long regions called non-coding regions that do not code for amino acids. Their function is still a mystery, but the process called splicing removes these non-coding regions from the pre-mRNA transcript Figure 3.

  • "Ribosomes And Protein Synthesis Worksheet - 12-th Grade, Toms River High East School"

    The removed segment of the transcript is called an intron. The remaining exons are pasted together. An exon is a segment of RNA that remains after splicing. Interestingly, some introns that are removed from mRNA are not always non-coding. When different coding regions of mRNA are spliced out, different variations of the protein will eventually result, with differences in structure and function. This process results in a much larger variety of possible proteins and protein functions. When the mRNA transcript is ready, it travels out of the nucleus and into the cytoplasm. External Website This video will show you the important enzymes and biomolecules involved in the process of transcription, the process of making an mRNA molecule from DNA.

  • Questions For Chapter 13. Genetic Code

    From RNA to Protein: Translation Like translating a book from one language into another, the codons on a strand of mRNA must be translated into the amino acid alphabet of proteins. Translation is the process of synthesizing a chain of amino acids called a polypeptide. The substrate on which translation takes place is the ribosome.

  • 12.4 Protein Synthesis (Translation)

    Ribosomes exist in the cytoplasm as two distinct components, a small and a large subunit. Transfer RNA tRNA is a type of RNA that ferries the appropriate corresponding amino acids to the ribosome, and attaches each new amino acid to the last, building the polypeptide chain one-by-one. Thus tRNA transfers specific amino acids from the cytoplasm to a growing polypeptide. The tRNA is modified for this function. On one end of its structure is a binding site for a specific amino acid. On the other end is a base sequence that matches the codon specifying its particular amino acid. This sequence of three bases on the tRNA molecule is called an anticodon. For example, a tRNA responsible for shuttling the amino acid glycine contains a binding site for glycine on one end. Equipped with its particular cargo and matching anticodon, a tRNA molecule can read its recognized mRNA codon and bring the corresponding amino acid to the growing chain Figure 3. Much like the processes of DNA replication and transcription, translation consists of three main stages: initiation, elongation, and termination.

    Initiation takes place with the binding of a ribosome to an mRNA transcript. Once the anticodon and codon sequences are bound remember, they are complementary base pairs , the tRNA presents its amino acid cargo and the growing polypeptide strand is attached to this next amino acid. This attachment takes place with the assistance of various enzymes and requires energy. External Website This video will show you the important enzymes and biomolecules involved in the process of translation, which uses mRNA to code for a protein. The transcript is decoded into a protein with the help of a ribosome and tRNA molecules. Commonly, an mRNA transcription will be translated simultaneously by several adjacent ribosomes. This increases the efficiency of protein synthesis.

    What happens to the small and large ribosomal subunits at the end of translation? Chapter Review DNA stores the information necessary for instructing the cell to perform all of its functions. Cells use the genetic code stored within DNA to build proteins, which ultimately determines the structure and function of the cell. This genetic code lies in the particular sequence of nucleotides that make up each gene along the DNA molecule.

  • 13-2 Ribosomes And Protein Synthesis

    A molecule of messenger RNA that is complementary to a specific gene is synthesized in a process similar to DNA replication. The molecule of mRNA provides the code to synthesize a protein. In the process of translation, the mRNA attaches to a ribosome. Next, tRNA molecules shuttle the appropriate amino acids to the ribosome, one-by-one, coded by sequential triplet codons on the mRNA, until the protein is fully synthesized.
