Answer:
A. FALSE
B. TRUE
C. FALSE
D. FALSE
Explanation:
A. DNA molecules consist of two strands of a helical chain of nucleotides, which are the monomer subunits of DNA.
B. Nucleotide subunits that make up a DNA strand are polar due to the presence of the phosphate group per subunit.
C. There are only four different nucleotides in a DNA strand. The nucleotides are different from each other based on the four nitrogen bases. These are adenine, thymine, cytosine, and guanine.
D. Hydrogen bonds are present between the nitrogen bases of nucleotides from anti-parallel DNA strands. Phosphodiester bonds, on the other hand are present between nucleotides of an individual DNA strand thus holding one DNA molecule together.
DNA contains the information to makeproteins, which carry out all the functions and characteristics of living organisms. ... In DNA, each protein is encoded by a gene (a specific sequence of DNA nucleotides that specify how a single protein is to be made).
Answer:
The correct answer would be the loss of its function.
Being protein in nature, the function of insulin depends on the amino acid sequence of the polypeptide chains.
Change in the amino acid sequence may result in a change of shape or structure of the protein.
Consequently, it would not be able to interact with cell surface receptors.
Thus, it would lose its function.
Answer:
sunlight hits the Earth most directly at the Equator. The curve of the Earth means that sunlight is spread over a wider area the further you move from the Equator. Sunlight hits a smaller surface area at the Equator so heats up quickly compared to the poles.
