Answer:
No, they do not all cause a change in amino acid sequence of a protein.
Explanation:
Substitution mutation is the type of mutation that results when the nucleotide base of a gene is replaced by another base in the sequence. A substitution mutation can result into three different types of mutation namely; silent mutation, missense mutation, and nonsense mutation.
- In silent mutation, the nucleotide base that gets replaced by another still forms a codon that encodes the same amino acid as in the original sequence. e.g if guanine replaces adenine in the sequence, TTA to form a mutated sequence, TTG. This mutated codon (TTG) still encodes LEUCINE amino acid just as TTA does. Hence, there is no effect on the resulting amino acid sequence. This portrays that NOT ALL SUBSTITUTIONS cause a change in amino acid sequence of a protein.
The gecko's feet contain molecules that are attracted to the molecules on the surface.
Geckos are lizards which belongs to reptile group. They are found in warm climatic regions of the world. Geckos and some other animals can climb smooth surfaces because of presence of Van der waal forces of attraction between the molecules of gecko's feet with molecules of the surface. The force of attraction is generated due to fluctuations or differences in charge present in molecules of feet and that of surface. The charge fluctuations generally comes into sync and generate attractive force.
<h3>What are the features of Geckos ?</h3>
Most geckos are small, soft-skinned reptiles that are often nocturnal in behaviour. A small, robust body, a big head, and often well-developed limbs are other features they have. Each limb's tips are frequently fitted with digits that have adhesive pads.
- The gecko possesses a variety of adaptive traits that help it avoid or confound predators. If a predator catches the gecko by the tail, the tail can be cut. One of the most well-known characteristics of the species is this. Some geckos may also alter their colour to better fit their surroundings.
