Name the sections of eukaryotic genes that are transcribed and translated?
Eukaryotic genes are comprised of several sections, with the two main ones being exons, which are transcribed and translated to form proteins, and introns, which are transcribed but not translated and are usually spliced out during pre-mRNA processing. Promoters and enhancers are other sections involved in regulating gene expression.
What is the ORF of a gene?
The ORF (open reading frame) of a gene is the portion of the gene that can be translated into a protein. It starts with a start codon (usually AUG) and ends with a stop codon (UAA, UAG, or UGA). Identifying the ORF is important for predicting the protein sequence encoded by a gene.
Why are there introns present in eukaryotic genes?
Introns are present in eukaryotic genes because they allow for alternative splicing, which enables a single gene to code for multiple proteins. This increases the diversity of proteins that can be produced from a single gene, allowing for greater complexity and regulation in eukaryotic organisms.
What Portion of DNA which carries the genetic code for the formation of a particular protein by specifying its amino acids sequence?
The portion of DNA that carries the genetic code for the formation of a particular protein is called a gene. Genes are specific sequences of nucleotides that determine the amino acid sequence of a protein. Genes are transcribed into messenger RNA (mRNA), which is then translated into the protein.
What types of DNA sequences help eukaryotic cells regulate gene expression?
Eukaryotic cells use various DNA sequences to regulate gene expression, including promoters, enhancers, and silencers. Promoters are located near the start of a gene and initiate transcription. Enhancers and silencers can be distant from the gene and help to enhance or repress gene expression, respectively. Together, these sequences play important roles in controlling when and how genes are expressed in eukaryotic cells.
What portion of an eukaryotic gene is not spliced out?
In a eukaryotic gene, the portion that is not spliced out is the exons. Exons are the coding sequences that remain in the mature mRNA after the introns, which are non-coding regions, have been removed during the splicing process. These exons are then translated into proteins, while the introns are discarded.
When was Critical Reviews in Eukaryotic Gene Expression created?
Critical Reviews in Eukaryotic Gene Expression was created in 1991.

What region of a prokaryotic gene is analogous to the enhancer region of a eukaryotic gene?
UP element
What region of a prokaryotic gene is analogies to the enhancer region of a eukaryotic gene?
UP element
How many deoxyribonucleotides are in a gene?
This can't be answered simply. Are we talking about prokaryotic or eukaryotic genes? If eukaryotic, there are a whole bunch of non-coding sequences that make up said gene that do not make it into the final translated product, but are required for the gene to get out of the nucleus and be translated into protein. I think the smallest gene recorded so far apparently encodes a 7amino acid protein - so the coding sequence alone for that gene would be 24 aa's (3 per each amino acid + 3 for the start codon, ATG). In my own graduate research, I have worked with genes that are over 25kb, that is, 25000 nucleotides long. There are certainly genes that are much larger than that, as well.
What are the two theories of evolution in a eukaryotic cell?
The two theories of evolution in a eukaryotic cell are endosymbiotic theory and gene duplication. Endosymbiotic theory suggests that eukaryotic cells evolved from a symbiotic relationship between different prokaryotic organisms. Gene duplication theory suggests that gene duplication events have played a significant role in the evolutionary development of new functions and complexity in eukaryotic cells.
Why are there introns present in eukaryotic genes?

Do eukaryotic microorganisms have ribosomes?
Naturally, all eukaryotic organisms, unicellular and multicellular, contain ribosomes. Even eukaryotic microorganisms require ribosomes for life because ribosomes are essential in the process of gene expression.
