Answer:
Instead of arginine codon, proline condon would be coded.
Explanation:
GCA encodes codes for glycine while on the other hand codon to GGU, GGC, or GGG encodes for glycine.
This substitution will lead to generation of complementary code “Proline” in the complementary mRNA or DNA strand.
The codon CCT, CCC, CCA, CCG encodes for proline. If this mutation would not have occurred then Arginine would have been encoded in the complementary codon with base structure of CGT, CGC, CGA, CGG
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:
B. Meiosis I
Explanation:
In meiosis I, it starts with a diploid cell with a homologous chromosome pair. The crossing of genetic material between chromosome pairs also occurs in this stage. The alleles containing the same trait would get separated so a new combination of alleles can be produced.
False. Specific gravity usually means relative density with respect to water. [ ]
