The result of DNA replication is two DNA molecules consisting of one new and one old chain of nucleotides. This is why DNA replication is described as semi-conservative, half of the chain is part of the original DNA molecule, half is brand new.

What is the end result of DNA replication quizlet?

The outcome of DNA replication is two DNA nearly identical DNA double helix molecules. Each DNA is made up of one DNA strand from the original DNA and a newly created strand.

What is at the end of DNA?

Each end of DNA molecule has a number. One end is referred to as 5' (five prime) and the other end is referred to as 3' (three prime). The 5' and 3' designations refer to the number of carbon atom in a deoxyribose sugar molecule to which a phosphate group bonds.

What is the end replication problem?

The end-replication problem

The DNA at the very end of the chromosome cannot be fully copied in each round of replication, resulting in a slow, gradual shortening of the chromosome. ... When DNA is being copied, one of the two new strands of DNA at a replication fork is made continuously and is called the leading strand.

What is the result of replication?

Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. ... Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, as the parent cell.

What is the end result of translation?

When the ribosome reaches a stop codon, it releases the mRNA strand and amino acid sequence. The amino acid sequence is the final result of translation, and is known as a polypeptide. Polypeptides can then undergo folding to become functional proteins.

What is the end product of transcription?

The product of transcription is RNA, which can be encountered in the form mRNA, tRNA or rRNA while the product of translation is a polypeptide amino acid chain, which forms a protein.

Which of the following is the end result of transcription?

The end product of transcription is an RNA molecule. Hence, copying the information of genes in the genome into an RNA occurs during the transcription. The three main types of RNA produced by transcription are mRNA, tRNA, and rRNA.

What is the result of DNA transcription?

In transcription, a portion of the double-stranded DNA template gives rise to a single-stranded RNA molecule. ... Often, however, transcription of an RNA molecule is followed by a translation step, which ultimately results in the production of a protein molecule.

What is the end result and purpose of translation?

The molecule that results from translation is protein -- or more precisely, translation produces short sequences of amino acids called peptides that get stitched together and become proteins. The resulting peptides are then joined into proteins, which are responsible for your body's structure and functions. ...

What is the end result of synthesis?

The result of protein synthesis is a chain of amino acids that have been attached, link by link, in a specific order. This chain is called a polymer or polypeptide and is constructed according to a DNA-based code. ... The difference between a protein and a polypeptide is the form.

What is the end product of translation quizlet?

What is the end product of translation? Polypeptide chain to make a protein.

What are the 4 steps of replication?

• Step 1: Replication Fork Formation. Before DNA can be replicated, the double stranded molecule must be “unzipped” into two single strands.
• Step 2: Primer Binding. The leading strand is the simplest to replicate.
• Step 3: Elongation.
• Step 4: Termination.

Which cell stage does DNA replicate?

In the eukaryotic cell cycle, chromosome duplication occurs during "S phase" (the phase of DNA synthesis) and chromosome segregation occurs during "M phase" (the mitosis phase).

What are the two steps of DNA replication?

There are three main steps to DNA replication: initiation, elongation, and termination. In order to fit within a cell's nucleus, DNA is packed into tightly coiled structures called chromatin, which loosens prior to replication, allowing the cell replication machinery to access the DNA strands.

In which step is the end result a protein?

The end result of translation in protein synthesis is a newly made protein. During transcription, DNA is copied to messenger RNA (mRNA) in the...

What happens in DNA synthesis?

DNA biosynthesis occurs when a cell divides, in a process called replication. It involves separation of the DNA double helix and subsequent synthesis of complementary DNA strand, using the parent DNA chain as a template. ... “Replication forks” move in opposite directions to form the new DNA.

What is created at the end of the translation stage of protein synthesis?

In translation, the instructions in mRNA are read, and tRNA brings the correct sequence of amino acids to the ribosome. Then, rRNA helps bonds form between the amino acids, producing a polypeptide chain. After a polypeptide chain is synthesized, it may undergo additional processing to form the finished protein.

What is the result of translation quizlet?

What is the end result of Translation? One protein or a long chain of amino acids.

How does termination of translation take place?

Translation ends in a process called termination. Termination happens when a stop codon in the mRNA (UAA, UAG, or UGA) enters the A site. ... After the small and large ribosomal subunits separate from the mRNA and from each other, each element can (and usually quickly does) take part in another round of translation.

What is the result of translation science?

The entire process is called gene expression. In translation, messenger RNA (mRNA) is decoded in a ribosome, outside the nucleus, to produce a specific amino acid chain, or polypeptide. The polypeptide later folds into an active protein and performs its functions in the cell.

What happens at the 5 end?

What happens at the 5' end of the primary transcript in RNA processing? it receives a 5' cap, where a form of guanine modified to have 3 phosphates on it is added after the first 20-40 nucleotides. What happens at the 3' end of the primary transcript in RNA processing?

What happens during the termination step of DNA transcription?

Step 3: Termination

Termination is the ending of transcription, and occurs when RNA polymerase crosses a stop (termination) sequence in the gene. The mRNA strand is complete, and it detaches from DNA.
