A scientist might choose mitochondrial DNA (mtDNA) over ribosomal RNA (rRNA) as a molecular clock because mtDNA typically has a higher mutation rate, allowing for more precise tracking of evolutionary changes over shorter timescales. Additionally, mtDNA is maternally inherited and does not undergo recombination, which provides a clearer lineage history. In contrast, rRNA evolves more slowly and can be less informative for recent divergences. This makes mtDNA particularly useful for studies of population genetics and phylogenetics in closely related species.
The nucleolus is responsible for the production of ribosomal RNA (rRNA) and the assembly of ribosomal subunits but does not directly produce ribosomes in quantifiable numbers per day. Instead, it synthesizes rRNA and combines it with proteins to form ribosomal subunits, which then exit the nucleolus and the nucleus to function in protein synthesis. The exact number of ribosomal subunits produced daily can vary significantly depending on the cell type and its metabolic activity.
Alleles of a gene are found at the same locus on homologous chromosomes, not on homologous mitochondria. Mitochondrial DNA is typically inherited maternally and is not organized in homologous pairs like nuclear DNA. Instead, there are multiple copies of the mitochondrial genome within each mitochondrion, and variations or mutations in this DNA can occur, but they do not represent alleles in the same way as nuclear genes. Therefore, the concept of alleles at a locus is primarily applicable to nuclear DNA rather than mitochondrial DNA.
The molecular weight of Na+ is approximately 22.99 grams per mole, which is the atomic weight of sodium. Since Na+ is an ion, it does not form molecules but instead exists as a single charged atom.
The molecular formula out of the options provided is CO, which represents a carbon atom and an oxygen atom bonded together. The other options, Co and C2O4, do not represent a molecular formula but instead may refer to cobalt (Co) and oxalate ion (C2O4^2-), respectively.
The organism that has mitochondria with disc-shaped cristae is fungi. Fungi have mitochondrial cristae that are organized into flat, disc-shaped structures instead of the typical tubular or finger-like cristae found in other organisms like animals. This unique morphology of mitochondrial cristae in fungi may be related to their specific energy requirements and lifestyle.
he wasn't a scientist but instead a mapmaker
Yes,I don't know!Tell me..!

A scientist uses formulas and facts instead of things you can see.
A scientific theory
Ribosomal RNA (rRNA) is involved in protein synthesis, but instead are an integral part of the ribosome machinery that is used to make proteins from mRNAs.
It is important for a scientist to be open minded but skeptical so that he/she will gather the information on a direct observation instead of on a feeling.
Aminoglycosides, such as gentamicin and kanamycin, do not inhibit cell wall synthesis. Instead, they disrupt protein synthesis in bacteria by binding to the 30S ribosomal subunit.

It is when a scientist, when questioned, gives a wrong or "made up answer" instead of just saying that he or she doesn't know. Witch is worse to the scientist name because it hurts their credibility.
