The cell needs to carry out transcription before it can begin translation because transcription is the first step of gene expression, whereby the segments of DNA is copied into RNA in other words mRNA by enzymes RNA polymerase.
The cell needs to carry out transcription before it can begin translation because transcription is the first step of gene expression, whereby the segments of DNA is copied into RNA in other words mRNA by enzymes RNA polymerase. Both RNA and DNA are nucleic acids and they use base pairs of nucleotides as complementary language. It is during transcription when DNA sequence is read by an RNA polymerase which produces antiparallel RNA, complementary strand called primary transcript. Transcription unit is the stretch of DNA which is transcribed into an RNA molecule and it encodes a protein then the transcription produces messenger RNA or mRNA the mRNA serves as a template for synthesis of proteins through the process of translation. The transcribed gene may encode for either ribosomal RNA or rRNA, non-coding RNA for example microRNA. RNA performs a fundamental role in functions within a cell whereby it helps to regulate, synthesize, and process proteins.<span> </span>
It should be the last one, but if you can pick more than one answer then I would do the first and last one but I’m confident that it would be the last one either way :) hopefully this is helpful
The example that does not exhibit sexual selection is: D. male elephant seals fighting over territory and potential female mates The competition for territory is also one that helps the elephant seals survive. This is because a seal with a larger territory is likely to have access to a greater amount of resources, ensuring its survival.
