1. DNA is the polymer of deoxyribonucleotides that contain the nitrogenous base, pentose sugar and phosphate group. The phosphate is attached with the 3 C position of the deoxyribose sugar. This leads to teh formation of phosphodiester bond.

2. The DNA backbone consists of phosphate and sugar. The nitrogenous bases are inserted inside the DNA molecule. These nitrogenous bases are linked together by the hydrogen bonds.

3. The adenine binds requires two hydrogen bonds to bind with thymine. This provide complementary nature to the DNA molecule. Uracil is present instead of thymine in RNA .

4. The guanine binds requires three hydrogen bonds to bind with cytosine. More amount of energy is required to break their bonds.

During transcription the DNA base sequence is transcribed into a complementary mRNA sequence. A codon table like the one shown b

xxMikexx [17]

Answer:

b. Even though the DNA sequence changed, the sequence still codes for the same amino acid, so no change in phenotype will occur.

Explanation:

There is redundancy in the genetic code. That means that different codons can code for the same amino acids, so some mutations do not change the amino acid sequence of the protein.

Here, the amino acid is unchanged with the mutation.

If the amino acid sequence of the protein is the same, then the protein is not changed, so there will be no change in the phenotype

Answer:

According to Lamarck, organisms altered their behavior in response to environmental change. ... Their changed behavior, in turn, modified their organs, and their offspring inherited those "improved" structures.
