RNA polymerase

now unwound in the area that is needed so the RNA polymerase is able to help line up the nucleotides to create a complementary strand of the mRNA. Between the strands there are hydrogen bonds which are then separated apart. One of the strands is then able to be used as a template strand. Onto this template strand these is base pairing which is the DNA cytosine joining to the RNA guanine, DNA guanine joining to the RNA cytosine, DNA thymine joining to RNA adenine and DNA…

used to build a protein in a two-step process. Transcription is considered to be the first step of gene expression. It is known to be the process of making a copy of genetic information stored in a DNA strand into a complementary strand of messenger RNA (mRNA). The process of eukaryotic transcription can be separated into three phases, initiation, elongation and termination. This complex process involves various cell signaling methods as well as the activity of many enzymes. Genes are segments…

a. Introduction Lujo Hemorrhagic Fever is caused by a bi-segmented negative RNA virus that is one of several viruses known to cause viral hemorrhagic fever. The Lujo virus is part of the Arenaviridae family, which consist of several viruses categorized into two groups. The Lujo virus is categorized in the “Old World” group, which signifies that the virus in question was found in the Eastern Hemisphere, specifically the continent of Africa. The majority of the arenaviruses categorized in the…

deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) within organisms can be methylated while proteins can be either methylated or acetylated. The methylation of DNA and RNA is used for alternative splicing used for production of different mRNA molecules resulting in numerous new proteins. One of the molecules believed to perform the methylation is N6A or N6 methyladenosine. Methylation is the most observed modification to mRNA molecules. Methylation of both DNA and RNA ensures…

replication of itself mRNA transcribes DNA, tRNA translates mRNA into proteins. A pattern on nucleotide on a DNA strand is called a gene. The Central Dogma of molecular biology is: DNA codes for RNA which codes. for proteins Not all genes are expressed for the production of proteins, some have other tasks like making RNA. Some proteins are structural. Some proteins are made of hundreds or thousands of amino…

the gene to the protein product. This process is how DNA is coded for RNA, which basically is the turn code for the proteins in our body. DNA is in every living thing, which is the molecule that carries genetic material from the parents to their offspring. Basically, it is the most important thing in the human structure of the body. For it carries the necessary information that is needed for the construction of proteins and RNA. There is always decoding going on in the body which is using the…

A. RNA doesn’t have thymine. RNA uses Uracil. RNA can leave the nucleus. B. mRNA- mRNA is called the messenger DNA. This RNA can leave the nucleus and delivers information to other parts of the cell. tRNA- Transfers amino acids to proteins. Ribosomal RNA- Forms parts of ribosomal subunits C. Proteins must be synthesised constantly in order to use the codes from genes over and over again. 2. A. During transcription, the enzyme RNA polymerase binds to DNA and separates the DNA strands. It then…

In both prokaryotes and eukaryotes, it is a complex multistep process that’s regulated by a variety of enzymes and proteins. Prokaryotic and eukaryotic DNA replication are both bi-directional processes, the DNA polymerases work from the 5’ to the 3’ end, they both involve leading and lagging strands and primers are required2. The main differences result from the difference in complexity between both types of organisms. While prokaryotic DNA is circular, eukaryotes…

‘’DNA makes the RNA and RNA makes the protein.’’All biological cells with few exceptions in some follow this rule. This flow takes place through three fundamental processes: replication, transcription and translation. Central Dogma theory was modified when it was found that in some cases RNA carry the genetic information for DNA. The dogma is basically the transfer of sequenced information between information carrying biopolymers. There are three main classes of such biopolymers: DNA, RNA and…

Thus, the genetic code is the basis of the central dogma of molecular biology. Central dogma is nothing but the flow of genetic information in all living cells including human cells from DNA to RNA to proteins. The central dogma There are three classes of sequential biopolymers that encode information: DNA, RNA, and protein. The central dogma of microbiology describes the ways in which information flows among these three classes: DNA replication (DNA to DNA), transcription…
