Answer:
<u><em>PROPHASE</em></u>
Explanation:
The first stage in Meiosis I is prophase I. During this stage the DNA condenses into chromosomes. During prophase I, homologous chromosomes pair up and exchange sections of DNA. This is called recombination or crossing over
So, you would make a punnet square. You would put the capital S and lowercase s on the top of it and then the capital Y and lowercase y on the side. Then you should have SY, sY, Sy, and sy as your outcomes.

Antisense RNAs are utilized for gene regulation and specifically target mRNA molecules that are used for protein synthesis.
<h3>What is the function of Antisense Gene ?</h3>
Antisense RNAs play the crucial role in regulating gene expression at multiple levels, such as at replication, transcription, and translation.
- In addition, artificial antisense RNAs can effectively regulate the expression of related genes in host cells.
- Antisense gene therapy is a gene silencing technique similar to RNA interference, but uses a slightly different mechanism.
- The therapy is called a gene silencing technique because, instead of repairing the gene, it aims to “silence” the gene's effect.

Answer:
The correct option no is 2. To determine if they are prokaryotic or Eukaryota she should look for the <u>nucleus.</u>
Explanation:
Prokaryotes can be described as organisms that are single-celled and lack membrane-bound organelles. Eukaryotes can be described as multicellular organisms and they possess membrane-bound organelles.
In Eukaryotes, the hereditary material is present inside a membrane-bound organelle termed as the nucleus. The prokaryotes do not have a nucleus and their hereditary material is present in the cytoplasm. Hence, option no 2 is correct.
Other structures like DNA and ribosomes are present both in the prokaryotic and eukaryotic cells.
Answer:
It is due to the proofreading activity of RNA polymerase.
Explanation:
RNA polymerase is the most significant enzyme of transcription process which deals with the synthesis of RNA from DNA.
RNA polymerase reads the template DNA or antisense strand of DNA and helps in the addition of correct nitrogen bases to the growing RNA strand that is complementary with respect to the nucleotides present within the template DNA strand.
After the addition of bases to the growing RNA strand the proofreading process take place in to verify that all the incorporated bases within the growing RNA chain is correct or not.If any incorrect base is incorporated in the growing RNA strand then the proofreading process replace that incorrect base with the correct one.
All this processes occur in very quick succession that"s why RNA polymerase can locate a promoter sequence faster than two molecules can collide.
