- 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. gene is a sequence of DNA that determines a particular trait. A chromosome is a coiled DNA chromosome that contains the organisms genetic code (aka-genes). 6 people found this useful. Edit.

How do genes direct the production of proteins? Most genes contain the information needed to make functional molecules called proteins. (A few genes produce other molecules that help the cell assemble proteins.) The journey from gene to protein is complex and tightly controlled within each cell.It consists of two major steps: transcription and translation. Together, transcription and translation are known as gene expression.During the process of transcription, the information stored in a gene’s DNA is transferred to a similar molecule called RNA (ribonucleic acid) in the cell nucleus.ogether, transcription and translation are known as gene expression. During the process of transcription, the information stored in a gene’s DNA is transferred to a similar molecule called RNA (ribonucleic acid) in the cell nucleus.

Biology DNA and Replication + Protein Synthesis PART A. Read the following: Protein synthesis is the process used by the body to make proteins. The first step of protein synthesis is called Transcription. It occurs in the nucleus. During transcription, mRNA transcribes (copies) DNA. DNA is “unzipped” and the mRNA strand copies a strand of DNA. Once it does this, mRNA leaves the nucleus and goes into the cytoplasm. mRNA will then attach itself to a ribosome.

Gene Expression Given this statistic, it is not surprising that the primary control point for gene expression is usually at the very beginning of the protein production process — the initiation of transcription. RNA transcription makes an efficient control point because many proteins can be made from a single mRNA molecule.t the same time, however, other amino acids would bind to negative regulatory proteins called repressors, which in turn bind to regulatory sites in the DNA that effectively block RNA polymerase binding (Figure 3). The control of gene expression in eukaryotes is more complex than that in prokaryotes.

Eukaryotic transcription When transcription is arrested by the presence of a lesion in the transcribed strand of a gene, DNA repair proteins are recruited to the stalled RNA polymerase to initiate a process called transcription-coupled repair.Central to this process is the general transcription factor TFIIH that has ATPase activity.hen transcription is arrested by the presence of a lesion in the transcribed strand of a gene, DNA repair proteins are recruited to the stalled RNA polymerase to initiate a process called transcription-coupled repair.

HOW DNA CONTROLS PROTEIN SYNTHESIS BY MEANS OF A BASE CODE Messenger RNA then passes out of the nucleus and travels to small structures called ribosomes in the cytoplasm. Here the message it contains is interpreted, and a protein is built up, bit by bit, from its individual subunits -- , which are in the cytoplasm.

Which cell organelle controls the synthesis of enzymes? Best Answer: Trust me, it's the nucleus. That's where the DNA is, on chromosomes, and DNA controls the synthesis of every protein in the body. Proteins are made in the ribosome, which is in the nucleus too, and once they are made, they are sent to wherever they are needed in the cell, depending on their function.

Control of Gene Expression Transcription can only occur if RNA polymerase first attaches, or binds, to the DNA. Controlling this binding process is the major way that gene expression is controlled, and proteins are the major controllers of binding.

PROKARYOTIC CELL ANATOMY: DNA replication is bidirectional from the origin of replication. To begin DNA replication, unwinding enzymes called DNA helicases cause short segments of the two parent DNA strands to unwind and separate from one another at the origin of replication to form two Y-shaped replication forks.) . In bacteria, Par proteins function to separate bacterial chromosomes to opposite poles of the cell during cell division. They bind to the origin of replication of the DNA and physically pull or push the chromosomes apart, similar to the mitotic apparatus of eukaryotic cells.

- DNA is a long molecule made up of twisted strands of the bases A, T, C and G. Genes are sections of the DNA and each gene has the code for creating a specific protein. The sequence of bases in the gene controls which amino acids are created and joined to make a specific new protein or enzyme molecule.NA is a long molecule made up of twisted strands of the bases A, T, C and G.

- The blocking of RNA polymerase consequently stops the transcription of the genes in the operon. The process by which a repressor inhibits transcription is called repression. Transcription of the structural genes is ultimately controlled by a regulator gene, which codes for the production of the repressor protein.he blockage of transcription by the action of a repressor protein is called repression. A regulator gene controls the expression of a particular gene by coding for a repressor protein. An inducer is a molecule that initiates gene expression.

The trp Operon - a repressible system The trp Operon - a repressible system. The trp operon of E. coli controls the biosynthesis of tryptophan in the cell from the initial precursor chorismic acid. This operon contains genes for the production of five proteins which are used to produce three enzymes. The products of the E and D genes form a multimeric protein comprised of two copies of each protein to produce the enzyme anthranilate synthetase.

Module 1 Part C: DNA structure and function, Genetic Engineering and Cancer A segment of DNA that contains the recipe for building one protein is called a gene. Genes occur on chromosomes. Mutations in genes can cause metabolic errors and genetic diseases. Without an understanding of DNA structure, it was unclear to scientists how DNA was used by cells.

- Once the two strands are separated a small piece of RNA, called an RNA primer, is attached to the DNA by an enzyme called DNA primase. These primers are the beginnings of all new DNA chains since the enzyme responsible for the copying of the DNA, DNA polymerase, can not start from scratch.nder normal conditions the DNA is packed into a compact structure called chromatin. To be able to replicate, the cell has to unfold and unwind the DNA, and also has to separate the two strands from each other. The cell has a complex machinery to perform these tasks.

HOW DNA CONTROLS PROTEIN SYNTHESIS BY MEANS OF A BASE CODE In order to do this, information from certain portions of the DNA in the chromosomes must be taken out into the cytoplasm, to be used to make (synthesise) control proteins (enzymes, etc) for the cell. There are 2 parts to this process: transcription and translation.

- A transcription factor (blue) binds to DNA (red) and alters which genes are turned on, or expressed. Image courtesy of David S. Goodsell, RCSB Protein Data Bank. Transcription factors are proteins that control which genes are turned on or off in the genome.They do so by binding to DNA and other proteins.Once bound to DNA, these proteins can promote or block the enzyme that controls the reading, or “transcription,” of genes, making genes more or less active.Transcription factors are essential for the regulation of genes.hrough the action of transcription factors, the various cells of the body, which all have the same genome, can function differently. These proteins are so important to life that they are found in all living organisms. Roughly 8% of genes in the human genome encode transcription factors.

How does the nucleus control which protein are made by the ribosomes? DNA is a double helix. When a protein is going to be made only the section of DNA that codes for that specific protein splits into two strands so that an mRNA molecule can copy it.Because mRNA can only copy the portion of DNA that codes for the specific protein, of is in this way that the nucleus controls which proteins are produced.NA is a double helix. When a protein is going to be made only the section of DNA that codes for that specific protein splits into two strands so that an mRNA molecule can copy it.
