How does dna make rna?

Question

Please in plain english so that I can understand.

Answer 1

DNA is double stranded, and because of the semi-conservative property of DNA, one strand is the exact complement of the other strand. In transcription, the creation of mRNA from DNA, only one strand is needed.

First, the DNA must be "unzipped" to allow the enzymes to attach to the bases. This is done by DNA Helicase. After the DNA is unzipped and a replication "bubble" is created, RNA polymerase can do its job. The job of RNA polymerase is to "read" the DNA strand and attach RNA bases to the DNA bases, creating a complement strand. However, because this is ribonucleic acids, not deoxyribonucleic acids, instead of a T for DNA, uracil, or U is used instead. RNA Ligase will then join the bases together, forming a solid phosphate backbone for the mRNA. After this is all completed, the mRNA will separate from the DNA and be sent to the ribosomes either on the nuclear envelope or the free-floating ones.

Answer 2

although DNA is found in the nucleus, proteins are made in the cytoplasm. a messenger molecule is used to carry the information from the nucleus to the ribosomes in the cytoplasm. the messenger is a molecule called messenger RNA (mRNA). IT COPIES THE INSTRUCTIONS FROM THE DNA, AND THEN TAKES THEM OUT TO THE RIBOSOMES.

Answer 3

The process is called transcription, at least in the case of mRNA.  It involves RNA nucleotides attaching to strands of DNA and in doing so making a perfect compliment to the DNA.  These nucleotides are ligated, or glued, together to make an RNA strand.  That's all you asked for, there are processes involved afterwards in removing certain pieces and translating the RNA to make proteins, but that goes beyond your question.

Answer 4

DNA is double stranded. RNA is synthesized by RNA polymerase using the template strand. So the RNA has the same sequence of the coding strand, except that uracil is in the place of thymine. The process is called transcription, because both DNA and RNA are using the same language. The information is simply transcribed, or copied.

Answer 5

okay DNA is composed of 2 strands....and rna is only single stranded so DNA just opens up a little bit and provides a sequence for the RNA maker [called RNA polymerase] to come and put the complementary bases and once the RNA strand is complete..the single strand of RNA leaves..and DNA recombines...

I really hope that help. I cant make it any simple

If you know more abt it ..then you know that DNA is compose of ATCG bases and RNA has AUCG -- so wherever the single strnd of DNA has an A RNA makes puts U, where DNA has a T it put A
