What does DNA have that RNA does not have?
its uracil
How does the structure of RNA differ than DNA?
In protein formation, mRNA carries codes from the DNA in the nucleus to the sites of protein synthesis in the cytoplasm (the ribosomes). Ribosomes are composed of rRNA and protein; they can "read" the code carried by the mRNA. A sequence of three nitrogenous bases in mRNA specifies incorporation of an amino acid; tRNA brings the amino acids to the ribosomes, where they are linked into proteins.
How is RNA differrent from DNA?
DNA is double stranded while rna is single stranded. DNA contains the bases a, g, t, c while RNA contains the bases a, g, c, u. See Protein Synthesis. they are also different because they have different meaning DNA is deoxyribonucleic acid and RNA is ribonucleic acid.
How do scientists classify viruses?
Scientists classify viruses based on their genetic material, replication mechanism, and structure. They use criteria such as genome composition (DNA or RNA), morphology (shape and structure), host range, and mode of transmission to categorize viruses into different families, genera, and species. This classification system helps researchers understand the diversity of viruses and track their evolutionary relationships.
Explain how RNA is made during transcription?
The transcription of mRNA begins in the nucleus. The DNA is uncoiled and the nucleic acids with nitrogen bases adenine, thymine, guanine, and cytosine combine to form an incomplete mRNA. The current RNA contains exons (the coding region) and introns (non-informational regions). The introns are cut out and remaining exons are spliced together. Now the mRNA goes through polyadenylation. This is the process where the 3' end of the mRNA is attached with multiple adenine nucleotides. On the 5' end of the mRNA, a 5' cap is attached. This is the complete and functional mRNA. At this point, the mRNA exits the nucleus to join with the ribosome, ending the transcription and starting the process of translation.

DNA vs RNA
What is not true about DNA and rna?
Basic rundown- Similarities: They are both Nucleic Acids and carriers of our genetic information; Three of Four common nucleotides are shared in both: ACG (Adenine, Cytosine, Guanine). Differences: RNA has U (Uracil), DNA has T (Thymine). RNA has a ribose sugar vs DNA's deoxyribose sugar (literally a one oxygen molecule difference). DNA gets Transcribed into RNA. RNA gets Translated into Amino Acids/Proteins.

How is DNA separated into distinct bars (what is the difference between the bars at the bottom vs the bars at the top)?
Nucleic acid electrophoresis is an analytical technique use to separate DNA or RNA. The DNA fragments of different lengths are visualized using a fluorescent dye
What is a gel used for in molecular biology research?
A"gel" generally refers to an agarose gel which is used to visualise DNA, determine the size of DNA and even a tell you a bit about its's structure (supoercoiled DNA vs linear DNA). However some gels can also be used to look at protein (often as a "western blot" gel) or RNA. The size of DNA, RNA or protein can be determined by how fast it moves across the gel when you pass an electrical current through it.

Why are RNA primers needed?
RNA primers are used to initiate the DNA replication at the template strand. DNA molecules require a free 3' OH, to which it could add the nucleotides. This free 3' OH is provided by the RNA primer. So prior to the synthesis of DNA a short fragment of RNA is synthesized that is later excised and filled with DNA molecules.

What is the video DNA vs The Book of Mormon about?
The video "DNA vs The Book of Mormon" challenges the very first lines in the Book of Mormon (in which it states that the people were descendants of Israelites) and claims they are a lie, and attempts to prove it's point through scientific DNA testing.
