Question

1. What feature of amino acids give protein their structure and function?
2. Why do phospholipids spontaneously form bi-layer membranes?
3. Does RNA base pair? Explain.
4. What area of biology studies how DNA works?
5. What are the monomers of protein, nucleic acid, and starch?
6. What are the bonds between amino acids called?

Answer 1

1) The function of protein is because of its structure and its structure is determined by the sequence of amino acids present in it. The primary structure of protein drives its folding and final structure. Primary structure of protein is a linear sequence of amino acids present in a peptide chain.

2) when exposed to water, phospholipids spontaneously form bilayers because phospholipids have hydrophobic tails. In order to hide their hydrophobic tails they organize in a bilayer. This process doesn't require energy.

3) RNA has 4 bases- adenine, guanine, uracil and cytosine. Adenine base pairs with uracil and guanine with cytosine.

4) molecular biology is concerned with the dna and its interactions.

5)monomers of protein- amino acid, nucleic acid- nucleotides( monomers composed of 5- carbon sugar, phosphate and nitogenous base), starch- glucose.

6)peptide bonds are bonds formed between aminoacids.
