Why Is speed more important in replication than in transcription?
why is speed more important in replication than in transcription? Speed in replication is more important than in transcription because the DNA polymerase are required to replicate larger regions of DNA and speed will help the replication process to complete the replication quickly.
What are some similarities and differences between replication and transcription?
Transcription copies the DNA into RNA, while replication makes another copy of DNA. 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.
What are the similarities between transcription and translation?
During transcription, RNA (Ribose Nucleic Acid) is synthesized from DNA (De-oxy Ribose Nucleic Acid), and during translation, protein or polypeptides are synthesized from RNA (It is mRNA or messenger RNA actually, which is nothing but the RNA containing genetic information of the cell as compared to the tRNA and the …
What are two differences between replication and transcription?
DNA replication is defined as the process involved in obtaining two daughter strands where each strand contains half of DNA double helix. Transcription, on the other hand, is the process of transferring genetic information from DNA to RNA. …
What is the difference between replication transcription and translation?
Transcription involves the conversion of DNA into RNA, it is helpful in gene expression of the selected segment of DNA. Translation is said as the final step where protein formation takes place.
What is the difference between replication and repetition?
Repetition & Replication. Repetition is the “repeating“ (multiple trials) of your own investigation for accuracy. Replication occurs when the investigation is “replicated” or copied by a different investigator.
Why are both strands not copied during transcription?
The two RNA molecules, if produced simultaneously would be complementary to each other, hence would form a double stranded RNA.
Are both DNA strands copied during transcription?
The mechanism of transcription has parallels in that of DNA replication. Unlike DNA replication, in which both strands are copied, only one strand is transcribed. The strand that contains the gene is called the sense strand, while the complementary strand is the antisense strand.
What will happen if both the strands of DNA are copied during transcription?
If there are transcriptional promoters on both strands of your template, then you will get RNA from both strands. Usually, when transcribing from plasmids and linear PCR products, there will only be one transcriptional promoter at a defined site.
What is the difference between a template strand and a coding strand?
For protein synthesis, messenger RNA must be made from one strand of DNA called the template strand. The other strand, called the coding strand, matches the messenger RNA in sequence except for its use of uracil in place of thymine.
Does the coding strand make mRNA?
The opposite strand (that is, the strand with a base sequence directly corresponding to the mRNA sequence) is called the coding strand or the mRNA-like strand because the sequence corresponds to the codons that are translated into protein. The upper strand of DNA is the “mRNA-like” strand.
Do the two strands remain unwound after transcription?
The template DNA strand and RNA strand are antiparallel. RNA polymerase always builds a new RNA strand in the 5′ to 3′ direction. That is, it can only add RNA nucleotides (A, U, C, or G) to the 3′ end of the strand.
Why is it called coding strand?
The other strand is called the coding strand, because its sequence is the same as the RNA sequence that is produced, with the exception of U replacing T. It is also called sense strand, because the RNA sequence is the sequence that we use to determine what amino acids are produced through mRNA.
What is a complementary DNA strand?
Complementary deoxyribonucleic acid (DNA) is DNA in which the sequence of the constituent molecules on one strand of the double stranded structure chemically matches the sequence on the other strand. The two strands are described as complementary to one another. …
What is the role of DNA coding strand?
During transcription, the coding strand of DNA serves as a template for synthesis of a complementary RNA molecule. The sequence of the RNA molecule is determined by complementary-base pairing so that the RNA is a complementary transcript (copy) of the coding strand of DNA.
What is genetic coding?
Genetic Code The instructions in a gene that tell the cell how to make a specific protein. Each gene’s code combines the four chemicals in various ways to spell out three-letter “words” that specify which amino acid is needed at every step in making a protein.
