Question 8 (Essay Worth 4 points)

DNA and RNA are nucleic acids and are composed of nucleotides. The structure of nucleic acids has an effect on their function.

a. Identify the type of chemical bond between nucleotides in these nucleic acids. Describe the directionality of structure in DNA and RNA.

b. Explain how a change in the subunits can affect their structure and function.



Answer :

GinnyAnswer

Final answer:

DNA and RNA nucleotides are connected by phosphodiester bonds, each with distinct structural directionality. Changes in subunits can impact structure and function through mutations.


Explanation:

The type of chemical bond between nucleotides in DNA and RNA is a phosphodiester bond. This bond forms between the phosphate group of one nucleotide and the sugar of the next nucleotide in the chain.

The directionality of structure in DNA and RNA differs. DNA is a double-stranded helix with antiparallel strands running in opposite directions, while RNA is single-stranded.

A change in the subunits of DNA or RNA can alter their structure and function. For example, a mutation in the nucleotide sequence of DNA can lead to changes in protein production, affecting the organism's traits.
