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..
What are two differences between DNA replication and RNA transcription?
Conclusion. Both DNA replication and Transcription involve the generation of a new copy of the DNA in a cell. DNA transcription is involved in replicating the DNA into RNA, while the DNA replication makes another copy of DNA. Both the process is involved in the production of new nucleic acids- DNA or RNA.
What is a difference between DNA replication and RNA transcription quizlet?
1. Replication makes DNA, Transcription makes RNA from DNA. 2. Replication occurs once, Transcription occurs over and over again.
How does DNA replication begin?
The initiation of DNA replication occurs in two steps. First, a so-called initiator protein unwinds a short stretch of the DNA double helix. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands.
What is the first step in DNA replication?
The first step in DNA replication is to ‘unzip’ the double helix structure of the DNA? molecule. This is carried out by an enzyme? called helicase which breaks the hydrogen bonds? holding the complementary? bases? of DNA together (A with T, C with G).
What is RNA used for?
RNA, abbreviation of ribonucleic acid, complex compound of high molecular weight that functions in cellular protein synthesis and replaces DNA (deoxyribonucleic acid) as a carrier of genetic codes in some viruses.
How does DNA and RNA work together?
The portions of DNA that are transcribed into RNA are called “genes”. … Cells make RNA messages in a process similar to the replication of DNA. The DNA strands are pulled apart in the location of the gene to be transcribed, and enzymes create the messenger RNA from the sequence of DNA bases using the base pairing rules.
What are 3 things DNA and RNA have in common?
The DNA and RNA Structures Both DNA and RNA have four nitrogenous bases each—three of which they share (Cytosine, Adenine, and Guanine) and one that differs between the two (RNA has Uracil while DNA has Thymine).
What are the 7 steps of DNA replication?
Steps in DNA ReplicationInitiation. DNA replication begins at specific site termed as origin of replication, which has a specific sequence that can be recognized by initiator proteins called DnaA. … Primer Synthesis. … Leading Strand Synthesis. … Lagging Strand Synthesis. … Primer Removal. … Ligation. … Termination.
Where does DNA replication occur?
DNA replication occurs in the cytoplasm of prokaryotes and in the nucleus of eukaryotes. Regardless of where DNA replication occurs, the basic process is the same. The structure of DNA lends itself easily to DNA replication. Each side of the double helix runs in opposite (anti-parallel) directions.
What are 5 differences between DNA and RNA?
DNA is a double-stranded molecule, while RNA is a single-stranded molecule. DNA is stable under alkaline conditions, while RNA is not stable. … DNA and RNA base pairing is slightly different since DNA uses the bases adenine, thymine, cytosine, and guanine; RNA uses adenine, uracil, cytosine, and guanine.
What are the similarities and differences between DNA replication & protein synthesis?
Protein synthesis and DNA replication are two mechanisms where double-stranded DNA molecules are involved in the initial template. Protein synthesis is the synthesis of an amino acid sequence of a protein. DNA replication is the synthesis of a new DNA molecule from an existing DNA molecule.
What do DNA replication and transcription have in common?
Similarities. Both DNA replication and transcription involve binding complementary nucleic acids to DNA, yielding a new strand of either DNA or RNA. Both processes can lead to errors if an incorrect nucleotide is incorporated.
What is the difference between DNA replication and RNA replication?
1. DNA replication is the process of making two daughter strand where each daughter strand contains half of the original DNA double helix. Transcription is the process of synthesis of RNA using DNA as a template. … To make RNA copies of individual genes.
What are the 4 main differences between DNA and RNA?
DNA is a long polymer with deoxyriboses and phosphate backbone. Having four different nitrogenous bases: adenine, guanine, cytosine and thymine. RNA is a polymer with a ribose and phosphate backbone. Four different nitrogenous bases: adenine, guanine, cytosine, and uracil.
What is DNA and RNA replication?
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. A short segment of RNA, called a primer, is then synthesized and acts as a starting point for new DNA synthesis. …
What happens during RNA replication?
During RNA replication, the gene-start and gene-end signals are ignored and an exact complementary copy of the genome (antigenome) is synthesized. RNA synthesis is tightly linked to encapsidation of the progeny molecule. A promoter located at the 3′ end of the antigenome is used to synthesize genome.
What are two major differences between DNA and RNA?
There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.
