The higher an animal is positioned on a cladogram, the more closely it is related to other animals.
Prokaryotic cells: do not possess membrane-bound organelles, and are relatively small—generally under 10 μm in size.
Both types of cells: utilize ribosomes for protein synthesis and contain DNA.
Eukaryotic cells: feature a complete set of DNA located within multiple chromosomes.
Specifically, prokaryotic cells lack a nucleus and membrane-bound organelles, resulting in their ribosomes floating freely within the cell. In contrast, eukaryotic cells possess a nucleus and membrane-bound organelles. Additionally, their DNA is associated with proteins and organized into chromosomes within the nucleus.
Answer:
Trojans Asteroids
Explanation:
Trojan Asteroids move in the orbit of a larger planet, where the gravitational forces of the sun and planets are in equilibrium, although I have uncertainity about the correctness of the answer. Good luck!
Question from alternative source
Numerous mutation types can arise in the body. Cystic fibrosis is a genetic condition attributed to various mutations in the CFTR gene. A specific mutation in the CFTR gene related to cystic fibrosis results in an earlier-than-expected termination of translation in the gene sequence. Which kind of mutation leads to this translation error resulting in cystic fibrosis?
- silent
- missense
- nonsense
- deletion
Answer:
Nonsense
Explanation:
Nonsense mutations refer to those that create a premature stop codon. The stop codons include UAG, UAA, and UGA. This situation could occur if a nucleotide substitution happens in the mRNA codon UAC (which codes for the amino acid Tyrosine) changing to UAG (which signifies a stop codon).
Upon reaching this codon, the translation machinery would interpret it as a directive to end translation. Consequently, the mRNA would be released, leading to a truncated version of the amino acid, which is likely not functional and could be flagged for destruction by the cell.
