Textbook Question
Chapter 2, Problem 1CP
Define atom.
Expert Solution & Answer
Summary Introduction
To define:
The term atom.
Introduction:
The smallest unit present on earth which makes all living and non-living things in different combinations is called an atom.
Explanation of Solution
The matter is made up of the most stable and smallest units. The uniqueness of each and every matter is decided by these atoms. The sub-atomic particles involved in the formation of atom are the protons, neutrons and electrons.
The mass and size of protons and neutrons is similar as compared to electrons which are light in weight. Protons and neutrons are positive and negative respectively. Neutrons are neutral in nature, thus have no electric charge. The nucleus is the central part of an atom having both proton and neutron which decides the total mass of an atom.
Conclusion
The matter is made up of the most stable and smallest units. The uniqueness of each and every matter is decided by these atoms.

- Molecular 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_forwardMolecular 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.
