Hi! Today were going to learn how DNA turns into protiens!
The genetic material is stored in the form of DNA has base pairs that get distributed to 23 pairs of chromosomes, and each cell has two copies of the genetic material. This is known as the human genome. The human genome contains around 30 000 genes, each gene has codes for one protein.
Each time a cell divides, its double strands of DNA splits into two single strands of DNA. Each of these single strands act like a template for a new strand of complementary DNA (complementary strand) this makes each new cell have it. this is DNA replication. Replication is controlled by the pairing of the bases in the first strand with incoming deoxynucleotide triphosphates, and is told what to do by the DNA polymerase enzymes. this is a very complex proces
Translation. The mRNA formed in transcription is transported out of the nucleus, into the cytoplasm, to the ribosome
Translation=mRNA leavin nucleus (DNA Can't move out of the nucleus) so RNA comes to get it!
Transcription is the process by which DNA is copied (transcribed) to mRNA, which carries the information needed for protein synthesis. Transcription takes place in two steps. First pre-messenger RNA is formed, with the involvement of RNA polymerase enzymes.The pre-messenger RNA is then "edited" to produce the desired mRNA molecule this process is called RNA splicing.
reverse transcription, RNA is "reverse transcribed" into DNA. TRANSLATION The mRNA formed in transcription is transported out of the nucleus, into the cytoplasm, to the ribosome (the cell's protein synthesis factory). Here, it directs protein synthesis. Messenger RNA is not directly involved in protein synthesis − transfer RNA (tRNA) is required for this. The process by which mRNA directs protein synthesis with the assistance of tRNA is called translation.
The mRNA formed in transcription is transported out of the nucleus, into the cytoplasm, to the ribosome. Here, it controls protein synthesis. Messenger RNA is not directly involved in protein synthesis − tRNA is required for this. The process where mRNA controls protein synthesis with the help of tRNA is called translation.
