DNA replication occurs in the nucleus. DNA transcription occurs in the nucleus. mRNA translation occurs at ribosomes. DNA replication occurs in the S-phase in interphase when the cell gets signal to start preparing for division. Here. the DNA will divide semi-conservatively. DNA transcription and DNA translation are part of protein synthesis. DNA transcription occurs by copying a length of DNA ...
Here are the steps of transcription. 1 ~ DNA is unzipped by the "Helicase" enzyme. 2 ~ RNA polymerase adds RNA nucleotides to the new RNA strand. (In RNA, thymine is replaced by uracil.) 3 ~ mRNA is complete when it reaches a stop code on DNA. 4 ~ mRNA then leaves the nucleus and carries the code to the sites of protein synthesis in the cytoplasm.
Jul 13, 2016. Transcription is the process of coding for RNA along genetic sequence of DNA. In prokaryotes it occurs along the circular DNA lying in nucleoid region within cell. Explanation: Prokaryotic cells lack nucleus. Inside the prokaryotic cell cytoplasm a naked DNA is present: the prokaryotic DNA is double helical and circular.
Explanation: Base pair in DNA replication is a way that the chromosomes have to double check to make sure that the duplication is exact. The replication is termed semiconservative since each new cell contains one strand of original DNA and one newly synthesized strand of DNA. The original polynucleotide strand of DNA serves as a template to ...
During the process of transcription, a portion of a DNA molecule is used to create a mRNA molecule. This is really important! DNA stores genetic information in the nucleus of your cells. When RNA molecules are produced it happens inside the nucleus. The RNA molecule can then leave the nucleus and travel to ribosomes which are located in the cytoplasm and attached to endoplasmic reticulum. The ...
Answer link. DNA is like the instruction manual for building and operating a cell. DNA replication needs to occur because existing cells divide to produce new cells. Each cell needs a full instruction manual to operate properly. So the DNA needs to be copied before cell division so that each new cell receives a full set of instructions!
It occurs in the nucleus. Since the DNA is in the nucleus and never comes out of it, transcription occurs in the nucleus.
Translation is the second phase of protein synthesis. It follows transcription, in which the information in DNA is "rewritten" into mRNA. During translation, the mRNA attaches to a ribosome. Transfer RNA (tRNA) molecules then "read" the mRNA code and translate the message into a sequence of amino acids. Every three nucleotides in the mRNA make ...
Nucleus B. tRNA C. Ribosomes D. Cytoplasm. Where does the transcription of DNA into mRNA occur in eukaryotes? A. Nucleus B. tRNA C. Ribosomes D. Cytoplasm. Problem 1RQ: The correct sequence of levels forming the structural hierarchy is A. (a) organ, organ system,...
Some mutations seem to not cause any problems but others are like a train wreck. The protein that should have been formed is unusable. Some well-known inherited genetic disorders include cystic fibrosis, sickle cell anemia, Tay-Sachs disease, phenylketonuria and color-blindness, among many others. All of these disorders are caused by the mutation of a single gene. Others are very rare, thank ...
