Answer:
The promoter region/sequence
Explanation:
Promoter sequences/region is where the transcription factors and RNA polymerase must attach before the gene can be transcribed. SO if we mutate this sequence, the transcription factors and RNA polymerase won't recognize it thus would not attach and transcribe the targeted gene.
Answer: Example for multiple alleles is human blood type
Explanation:
Blood types exsist as four possible phenotypes A,B,AB, and O .
The phospholipid molecule is both hydrophilic and hydrophobic which allows it to organize into a bilayer with the hydrophobic tales tucked away and the hydrophilic head exterior. This bilayer is also semipermeable allowing some small molecules in for the cell to use
Navado del ruiz is in Andes mountain range, and stratovolcano lava is named for that mountain range.
Where is Nevado del Ruiz volcano located?
- The Andes mountain range includes Nevado del Ruiz, which is located 129 kilometers (80 km) west of Bogotá.
- The Tolima, Santa Isabel, Quindio, and Machin volcanoes, as well as the Ruiz-Tolima volcanic massif (also known as the Cordillera Central), are among the five ice-capped volcanoes that make up this group.
- The massif is situated where four faults converge, some of which are still active.
- Nevado del Ruiz is an Andean stratovolcano, which is a large, roughly conical volcano made up of several strata of hardened lava and volcanic ash.
- The andesitic-dacitic composition of its lavas.
- The current volcanic cone is made up of five lava domes that were all built inside the caldera of an earlier Ruiz volcano. It extends 65 kilometers (40 miles) from east to west and has a surface area of more than 200 square kilometers (77 sq mi).
