Answer: C). The protein formed from the mutated strand will be the same as the protein formed from the original strand.
Explanation: The two protons have the same amino acid sequence therefore, the mutated protein is the same with the protein formed from the original strand. This is because the two codons AAA and AAG codes for the amino acid lysine. A phenomenon whereby an amino acid is specified by more than one codon is known as degeneracy. This does not mean that the genetic code is flawed but each codon specifies only one amino acid. The degeneracy of the codes are not uniform, some amino acids are specified by one codon, while some are specified by more than one codons. For example, methionine and tryptophan have single codons, Leucine, serine and arginine have six codons, isoleucine has three codons, alanine, glycine, and threonine have four codons.
Definition
A technique which is used to separate, DNA, RNA or protein pieces from each other under the influence of electric field on the basis of their molecular size is known as gel electrophoresis.
Explanation
This method is very reliable for separation of large size molecule (over 1 million Da). Materials which are required for gel electrophoresis include:
1. TAE stock buffer
2. 1% agrose gel
3. Nucleic acid loading dye
4. Ethidium bromide
Procedure:
First prepare a stock solution of TAE buffer by adding appropriate amount of TAE in distilled water. then prepare 1% agrose by adding 1X TAE, some amount of agrose in water and heating it in microwve oven to mix them will. then pour agrose gel on tray and fix comb in it and keep it untill agrose dry. Then remove comb and pour some quantity of nucleic acid along with loading dye and ethidium bromide in each well. EtBr is used for staining nucleic acid.
When sample is poured in all well also pour reference marker in one well for comparison. now connect it with voltage for 30-35 min. After this take gel and see it under UV. a large number of nucleic acid pieces will be seen on gel under UV. those pieces which have small molecular weight will cover more distance compared to those having larger molecular weight.
Answer:
Many animals that live in the tundra, like the caribou and the semipalmated plover, migrate to warmer climates during the winter. Others, like the arctic ground squirrel, hibernate during the winter months. There are very few reptiles and amphibians found in the tundra because the temperatures are so cold.

A.Vinegar and soda
Explanation;
-A salt is a substance that contains a cation which is a metal ion or an ammonium ion and an anion derived from an acid. It is an ionic compound that can be formed by the neutralization reaction of an acid and a base.
