What describes a difference between transcription and DNA replication?

Answer 1

DNA replication uses thymine.

Answer 2

DNA replication is the process by wich one double helix of DNA is dublicated into two identical double helices which are also identical to the mother DNA. The process is carried by specific enzymes.

RNA transcription is the process by which a messanger RNA copy of the active strand of a DNA helix is made. This process is carried by different enzymes and the result is a single strand of mRNA.

Answer 3

polymerase is an enzyme that catalyzes the conversion of free nucleotides into a single strand.

DNA polymerase differs from RNA polymerase in two major respects:

Like all enzymes, DNA polymerase is substrate-specific. DNA polymerase cannot extend a single strand of DNA; it needs at least a short segment of double-stranded DNA at the outset.

As its name implies, DNA polymerase incorporates deoxyribonucleotides into the new strand. RNA polymerase incorporates ribonucleotides.

These differences mean that DNA polymerase is active when new DNA strands are formed, as in DNA replication, and RNA polymerase is active when new RNA is formed, as in transcription.

Answer 4

DNA replication happens during interphase where DNA replicates itself through semiconservative replication to create an extra set of chromosomes for cell division. DNA is then transcribed into mRNA then produces proteins through DNA translation. This occurs by the tRNA picking up specific amino acids that contain anticodons and transferring them to the ribosome where it base pairs to the codon from the mRNA which controls the type of amino acid that is attached to the protein being formed.

Answer 5

Transcription is the process of synthesis of a new molecule of mRNA from a single strand of a DNA molecule, while a DNA replication is a semi-conservative process from where a new DNA molecule is formed from the original double helix molecule. Transcription event takes place anytime during cell lifespan while DNA replication only during cell division.

Answer 6

DNA transcription and DNA replication are two entirely different things. In replication, the double helix of DNA unzips itself. In transcription, DNA unzips an RNA.
