If want a direct answer it would be the decrease in mice, but if you want to get technical the decrease in grain spills caused mice to leave so that would be the indirect cause
Answer:
B) a signal-recognition particle that brings ribosomes to a receptor protein in the ER membrane.
Explanation:
Each synthesized protein has to be targeted to the specific location and transported to that location. There are two possible ways for that transport: post-translational transport or co-translational transport.
• Co-translational transport occurs during the process of translation, and proteins transported this way are proteins bound for organelles in the endomembrane system (such as the ER, Golgi apparatus, and lysosome), plasma membrane proteins or proteins for the exterior of the cell. They have an amino sequence called a signal peptide which sends them to ER first.
• Proteins that do not have a signal peptide stay in the cytosol so, their transport is after the translation (post-translational).
Answer:
Statements that are true are:
B) in splicing, intron sequences are removed from the mRNA in the form of lariats (loops), and are degraded = TRUE
C) one mRNA can sometimes code for more than one protein by splicing at alternative sites = TRUE
E) splicing occurs while the mRNA is still in the nucleus = TRUE
Statements that are false are:
A) splicing occurs while the mRNA is attached to the nucleosome = FALSE
D) splicing of mRNA does not involve any proteins = FALSE
)Sexual reproduction maintains a constant level of variation in the population and requires less energy.
Answer:
Mutations in the HBB (beta-globin) protein causes symptoms of sickle cell disease.
