Answer:Frameshift mutations are likely to change more than one amino acid, infact a completely irrelevant protein with altered amino acid sequence is produced.

Explanation:

Frameshift mutation is due to addition or deletion of bases. From that point onwards the reading frame shifts, different set of codons read. Frameshift mutations are likely to change more than one amino acid, infact a completely irrelevant protein with altered amino acid sequence is produced.

Frame shift mutation can lead to thalassemia due to premature chain termination and run-on-polypeptude that are non-functional.

21. Which step in cellular respiration occurs outside of the inner membrane space of the cell mitochondria? a. Krebs Cycle c. Tr
Marrrta [24]

Answer: c. Transition Reaction

Explanation:

During the transition reaction, Acetyl-CoA is formed and connects the first stage of glycolysis with the Krebs Cycle (Citric Acid Cycle). In the presence of oxygen, pyruvate enters the mitochondria and is oxidized to form a compound of 2 carbon, acetate, with energy and CO2 release. During this process, the acetate binds to a coenzyme(coenzyme A (CoA)) - forming the acetyl-coenzyme A.

The 3 steps:

1. pyruvate is oxidized and forms acetate with liberation of CO2;

2. the energy released in the oxidation of pyruvate is stored in the reduction reaction of NAD+ to NADH + H+

3. The acetate molecule combines with coenzyme A to form acetyl-coenzyme A.
