Both processes involve the generation of a new molecule of nucleic acids, either DNA or RNA; however, the function of each process is very different, with one involved in gene expression and the other involved in cell division. The first step in the process is the unwinding and separation of the two strands of the DNA helix. The mRNA is essentially the cellular blueprint for the construction of a particular protein. It travels from the nucleus to the cytoplasm, where it is translated into protein, a process known as gene expression. This is done in preparation for cell division, or mitosis. Before a cell divides, the DNA must be copied so that there is a copy for each of the resulting daughter cells. First, the DNA unwinds and the two strands of the helix separate.
Protein biosynthesis or protein synthesis is a core biological process, occurring inside cells , balancing the loss of cellular proteins via degradation or export through the production of new proteins. Proteins perform a number of critical functions as enzymes , structural proteins or hormones. Protein synthesis is a very similar process for both prokaryotes and eukaryotes but there are some distinct differences. Protein synthesis can be divided broadly into two phases - transcription and translation. This conversion is carried out by enzymes, known as RNA polymerases , in the nucleus of the cell. The mature mRNA is exported from the cell nucleus via nuclear pores to the cytoplasm of the cell for translation to occur. During translation, the mRNA is read by ribosomes which use the nucleotide sequence of the mRNA to determine the sequence of amino acids.
Replication is processed inside the nucleus and involves the copying of the genetic material so that the new daughter cell thus form contains the identical copies as their parent cells. Both the process occurs inside the cell. These involve the three main processes which are replication, transcription, and translation. Replication is the process of duplicating the ones own genetic materials into two more identical copies, so that the similar information may get further transfer to the new daughter cells. Translation is said as the final step where protein formation takes place.

Definition DNA replication is the process of making two daughter strand where each daughter strand contains half of the original DNA double helix. Purpose To conserve the entire genome for next generation. To make RNA copies of individual genes.
Transcription and translation are two main pillars of gene expression. Due to the different timings, spots of action, and mechanisms of regulation, these processes are mainly regarded as distinct and generally uncoupled, despite serving a common purpose. Here, we sought for a possible connection between transcription and translation. Employing an unbiased screen of multiple human promoters, we identified a positive effect of TATA box on translation and a general coupling between mRNA expression and translational efficiency. Suboptimal transcription rates lead to elevated m 6 A content, which may result in reduced translation. This study uncovers a general and widespread link between transcription and translation that is governed by epigenetic modification of mRNAs. Transcription of genome-encoded information into mRNA and translation of mRNA into a functional protein are the main layers of gene expression.

Translation is the synthesis of a protein from an mRNA template where the code in the mRNA is converted into an amino acid sequence in a protein. In prokaryotes both transcription and translation occur in the cytoplasm due to the absence of nucleus. In eukaryote transcription occurs in the nucleus and translation occurs in ribosomes present on the rough endoplasmic membrane in the cytoplasm.
This is an online quiz called Transcription and Translation. When the translation of mRNA starts, codons are read as successively without a space and. Transcribe is the verb associated with transcription. In eukaryotes, the separation prevents simultaneous transcription and translation, introducing a time lag, but also allowing processing of RNA transcripts. Translation—the conversion of one language to another—is much more difficult, whether in human language or in biochemical language.
Но он не смог примириться с тем, что этот взрыв лишил его возможности познакомиться с собственной матерью. Произведя его на свет, она умерла из-за осложнений, вызванных радиационным поражением, от которого страдала многие годы. В 1945 году, когда Энсей еще не родился, его мать вместе с другими добровольцами поехала в Хиросиму, где работала в одном из ожоговых центров.
Забавно, - сказала. - Последний файл из намеченных на вчера был загружен в одиннадцать сорок. - И. - Итак, ТРАНСТЕКСТ вскрывает один шифр в среднем за шесть минут.
Она показывает восемнадцать… - Коммандер Стратмор велел вам уйти. - Плевал я на Стратмора! - закричал Чатрукьян, и его слова громким эхом разнеслись по шифровалке. - Мистер Чатрукьян? - послышался сверху звучный возглас.
Он профессор лингвистики, а не физики. - Атакующие линии готовятся к подтверждению доступа. - Господи! - Джабба в отчаянии промычал нечто нечленораздельное.
