Explanation: just took it on Ap3x
Had to look for the options and here is my answer.
Basically, when we say eukaryotes, these are kinds of organisms which consists of cells that has DNA and other organelles that are enclosed by a membrane. In this case, the size of the primary transcript is generally THE SAME LENGTH the gene in the template of the DNA strand. Hope this helps.
Since the round seed gene is the dominant gene, it follows that, a cross between a round seed plant and a wrinkled seed plant will lead to only round seed offspring.
<h3>What is genetics?</h3>
Genetics is the science that studies the patterns of inheritance. The unit of inheritance located in the chromosome is called the gene.
Since the gene for having round seeds is dominant over the gene for having wrinkeled seeds, a cross between a round seed plant and a wrinkled seed plant will lead to only round seed offspring.

The<u> repressor </u>is a type of regulator protein that binds to a region of DNA in the promoter of a gene called the operator and prevents transcription from taking place.
In the field of science, a regulator protein can be described as a kind of protein that affects the transcription of a gene by having an influence on particular DNA sites. The rate of synthesis of various proteins is controlled by the regulator proteins.
A repressor is a kind of regulator protein that prevents the transcription of a particular gene. When the rate of a protein in the body has reached normal, the transcription of the protein needs to be stopped in order for more protein of that kind to be formed. The repressor binds itself to the operator region for the gene, hence stopping the transcription process until the protein is required again.
