The purpose of replication is to conserve the entire genome for next generation.
The purpose of transcription is to make RNA copies of individual genes that the cell can use in the biochemistry.
DNA replication is the replication of a strand of DNA into two daughter strands, each daughter strand contains half of the original DNA double helix.
Uses the genes as templates to produce several functional forms of RNA
One strand of DNA becomes 2 daughter strands. mRNA, tRNA, rRNA and non-coding RNA( like microRNA)
In eukaryotes complementary base pair nucleotides bond with the sense or antisense strand. Thesre are then connected with phosphodiester bonds by DNA helix to create a complete strand. …show more content…
Since there are 4 bases in 3-letter combinations, there are 64 possible codons (43 combinations).
RNA transcription follows base pairing rules. The enzyme makes the complementary strand by finding the correct base through complementary base pairing, and bonding it onto the original strand.
These encode the twenty standard amino acids, giving most amino acids more than one possible codon. There are also three 'stop' or 'nonsense' codons signifying the end of the coding region; these are the UAA, UAG and UGA codons.
DNA polymerases can only extend a DNA strand in a 5′ to 3′ direction, different mechanisms are used to copy the antiparallel strands of the double helix. In this way, the base on the old strand dictates which base appears on the new strand.
In replication, the end result is two daughter cells.
While in transcription, the end result is a RNA molecule.
Replication is the duplication of two-strands of
