Repressor slows down transcription.
RNA Polymerase enzyme transcribes mRNA from DNA.
Explanation:
Promoters are the 100 to 900 bps long sequence of DNA, that helps in the initiation of transcription. The transcription gets slow down as repressor bind to the promoter region hampering the attachment of RNA Polymerase enzyme which is responsible for transcription.
The process of transcription is the conversion of DNA into mRNA as told in the central dogma of molecular biology. Enzyme responsible for transcription is RNA polymerase. It is the first phase of gene expression, where DNA strand is copied into mRNA called a primary transcript.
Answer:
yes all coll have ribosomes
Mitosis and cytokinesis. In eukaryotes the processes of DNA replication and cell division occur<span> at different times of the </span>cell division<span> cycle. During </span>cell division<span>, DNA condenses to form short, tightly coiled, rodlike chromosomes. Each chromosome then splits longitudinally, forming two identical chromatids.

<span>The Human Genome Project had a very negative effect due to development
in technology and academic rivalry. With knowledge came bitter rivalry and with
technology came the tendency to become God. These angles greatly created
negative impact about this project. The experts tried to create human clones,
tissue engineering etc. The scientists
tried to analyze a person and get rid of any future disease that might attack
them. Some people feel this is good while others feel that it is like
distorting the natural process. </span>
Answer
Photosynthesis involves three elements: carbon, hydrogen, and oxygen. You have seen that the products of photosynthesis are oxygen and glucose. Their chemical formulas are shown below.
