AATTGCGGA would be the translation of the DNA sequence provided.

On the mRNA molecule, AAA codes for UUU; UUU delivers a phenylalanine amino acid to a growing polypeptide (Daempfle, 2016). AAA is called a triplet sequence on DNA. Its corresponding sequence on mRNA is termed a codon. A codon is a standard genetic code in which a sequence of three nucleotides codes for a specific amino acid. Start codons and stop codons signal the cell to start or stop translation. So if the DNA sequence listed in the question were changed to AAA after G, it would indicate a stop translation.

Prokaryote Dna Synthesis Lab Report

A group of three proteins known as the ‘prepriming complex’ are responsible for unwinding the double helix and keeping it separated. The first step is carried out by the DnaA protein. It binds to the origin nucleotides resulting in an AT rich region. The AT rich region sparks the separation of the double strand into single strands of DNA, the ATP dependent process of melting. DNA helicases are responsible for unwinding the helical structure of DNA.…

4.0Chapter four Discussion: 4.1 Point Counts By restraining the recording of species to a 10- 50m fixed radius when in dense forest at kamwala 1 forest, it allows the subtraction the certain bias, such as, the highly vocal forest species; White bellied Go Away bird and Tropical Bulbul, as well as those species which ‘generally’ occur above the canopy (for example; forest raptors). The most widespread species to occur across all the count areas (map 1) were Common Bulbul, Orange ground thrush and JoyfulGreenbul as well Red bellied paradise flycatcher, but orange ground thrush havens highly distributed in kamwala forest reserve. Although this is ecologically indicative of Rüppell's Robin-Chat, a forest edge species, it is unusual for Dusky Flycatcher which is usually found throughout forest stratum where it occurs 4 .2Birds abundance and diversity…

BIOL 1010 ASSIGNMENT 1 OCT 6 BY JORDAN KAPITANY ST 100883963 Among the many scientific achievements of the twentieth century in the field of bio-technology scientists Paul Berg, Herbert W Boyer, Stanley N Cohen and team for their research that lead the party to discover a technique of taking genes from one organism and inserting them into another organism, also more formally known as Deoxyribonucleic Acid or DNA recombinant technology. In 1971 Berg and team successfully isolated DNA of virus found in monkey's known as lambda then placed the genetic material into DNA sequence of a different simian virus called SV4O. This was done by first using a DNA enzyme, a naturally occurring molecule that has the unique chemicals properties to sever the bonds in the DNA sequence, from a very specific kind of…

However it is important to note that mutations will also lead to variability which is beneficial to us. Mutations in intergenic DNA affects regulations of protein products which is actually less detrimental than mutations in exons which code for the proteins. 2.…

Pros And Cons Of Gene Control

mRNA is translated from a five posion to a three position direction. The beginning end of this translated polypeptide is called the N- terminus, while the "three" end of the polypeptide is the C- terminus. The C terminus is where the stop codon is located and where translation processes end for that mRNA template. The main four phases of translation are pre- initiation, initiation, elongation, and termination. A basic transcription process starts out with a start codon where translation begins by ribosome initiation.…

Recently, I interviewed Dr. Dan Jernigan, the Director of the Influenza Division, for a school project. I had always known that the CDC was in Atlanta and tried to prevent disease on a global scale, but he truly opened my eyes to the wonders of Public Health and the CDC. My dad is a pediatrician, and I have always been interested in medicine, but he always seems to be playing a game of catch up. The disease comes first, then he has the task of fighting it off. Dr. Jernigan showed me a completely different and fascinating approach.…

Possible Modifications of Central Dogma of molecular Biology Introduction The central dogma of molecular biology is describes the transfer of genetic information within a biological system and was first stated by Francis Crick in 1956. The central dogma is the flow of genetic information as ‘’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.…

Introducing Nutrigenomics Genetics is the study of genes, which are molecules that are passed from parents to offspring. They are responsible for making the proteins in our bodies, and determining how similar or different we are from one another. “The topic of nutrigenomics is a branch of nutritional genomics, and is the study of the effects of foods and food constituents on gene expression”(Wikipedia). It studies specifically on the functional interactions of food, and its components with the genome at the molecular and cellular level, with the goal of using diets to prevent or treat diseases. Not only does it focus on functional interactions, but also combines the study of nutrition and genetics to discover the different ways people respond…
