A change in genotype, but not in phenotype, is most likely due to _________.

Answers

Answer 1
Answer:

A change in genotype, but not in phenotype, is most likely due to neutral mutation.

A mutation consists of a spontaneous and unpredictable change in the sequence of genes that make up the DNA of a living being.

  • A neutral mutation is one that has no consequences on the phenotype, that is, it has no effect on the observable characteristics of an organism.

  • Neutral mutations has effects on the genotype because it generates a change in the order of nucleotides that creates triplets that code for equivalent amino acids as basic amino acids.

Therefore, we can conclude that a neutral mutation does not affect the viability of the living being.

Today in class, a student asked whether the positive charge of the presequence of proteins being imported into the mitochondria was inhibitory for entry into the intermembrane space because of the positive charge present in this compartment of the mitochondria. How do proteins get past this? Wouldn't the net positive charge be inhibitory to import through the TOM complex?

Answers

Answer:

Mitochondrial proteins enter the organelle through channels formed by membrane proteins present in its inner and outer membranes.

Explanation:

All the biological membranes have lipid bilayer with the non-polar core that does not allow entry of charged and large substances. Mitochondrial proteins are synthesized in the cytosol and the unfolded proteins bind to the chaperons that deliver them to the receptors present in the outer mitochondrial membrane.

The receptor moves the protein to the membrane channels formed by integral membrane proteins of inner and outer mitochondrial membranes. The proteins enter the intermembrane space and are targeted to the inner membrane through channels while chaperons are left outside only.

Answers

Answer:

red-hot iron bar

Explanation:

An iceberg could even contain more heat energy than a cup of coffee or a red-hot iron bar. That's because its bigger and contains so many more molecules, each of which has some heat energy. The coffee and the iron bar are hotter (have a higher temperature), but the iceberg holds more heat because it's bigger.

The poly(A) sequence that is added to RNA during processing: helps prevent rapid breakdown of the messenger RNA. is needed for ribosomes to attach to messenger RNA. aids in the accuracy of translation of the messenger RNA into protein. helps prevent formation of complex three-dimensional structures in the messenger RNA.

Answers

Answer:

Option A, helps prevent rapid breakdown of the messenger RNA

Explanation:

The poly-A tail is a chain of adenine nucleotides which when get attached to the messenger RNA during RNA processing enhances the stability of the molecule and therefore prevents it from breaking down. This is required because after the transcription of gene in a eukaryotic cell, newly formed RNA molecule undergoes several modifications. It also helps is preventing the new RNA from enzymatic degradation in the cytoplasm and translation.

Hence, option A is correct
