Introduction:
Generally, four basic kinds of biological macromolecules are available in biological system. These molecules made up of different monomers and serve diverse functions and identified as carbohydrates, lipids, proteins and

Answer to Problem 1E
Solution:
Correct answer is option (b) phospholipids.
Explanation of Solution
Explanation/justification for the correct answer:
Option (b) phospholipid. Generally, phospholipid molecules consist of hydrophilic head consisting of a phosphate group and two hydrophobic fatty acid tails. Phospholipids are a type of lipids and component of all cell membranes; they are capable to make lipid bilayers on plasma membrane due to its amphiphilic characteristic. Hence, option (b) phospholipid is not a polymer and it is a correct answer.
Explanation for incorrect answer:
Option (a) polysaccharide. Biological
Option (c) Proteins, Proteins are composed of monomers which known as amino acid. Due to variably in amino acid sequences and its conformation they exhibit variety of functions such as transportation of molecules and muscle movement. So, this is an incorrect answer.
Option (d) nucleic acids , nucleic acids molecules consist of
Polymer is a complex structure that consists of monomers of bimolecul. They play verity of function for survival and maintains of cells. Hence, phospholipid is not made up of monomer unit of lipid and not polymer, the correct answer is option (b).

- What is this?arrow_forwardMolecular Biology A-C components of the question are corresponding to attached image labeled 1. D component of the question is corresponding to attached image labeled 2. For a eukaryotic mRNA, the sequences is as follows where AUGrepresents the start codon, the yellow is the Kozak sequence and (XXX) just represents any codonfor an amino acid (no stop codons here). G-cap and polyA tail are not shown A. How long is the peptide produced?B. What is the function (a sentence) of the UAA highlighted in blue?C. If the sequence highlighted in blue were changed from UAA to UAG, how would that affecttranslation? D. (1) The sequence highlighted in yellow above is moved to a new position indicated below. Howwould that affect translation? (2) How long would be the protein produced from this new mRNA? Thank youarrow_forwardMolecular Biology Question Explain why the cell doesn’t need 61 tRNAs (one for each codon). Please help. Thank youarrow_forward
- Molecular Biology You discover a disease causing mutation (indicated by the arrow) that alters splicing of its mRNA. This mutation (a base substitution in the splicing sequence) eliminates a 3’ splice site resulting in the inclusion of the second intron (I2) in the final mRNA. We are going to pretend that this intron is short having only 15 nucleotides (most introns are much longer so this is just to make things simple) with the following sequence shown below in bold. The ( ) indicate the reading frames in the exons; the included intron 2 sequences are in bold. A. Would you expected this change to be harmful? ExplainB. If you were to do gene therapy to fix this problem, briefly explain what type of gene therapy youwould use to correct this. Please help. Thank youarrow_forwardMolecular Biology Question Please help.
