List several ways in which meiosis differs from mitosis.

To write:
Differences between meiosis and mitosis.
Introduction:
There are two types of cell division- (a) Meiosis and (b) Mitosis. The meiotic process occurs in gametes whereas, the meiotic process occurs in body cells. Precise genetic copies of the parent cell are the new cells produced as a result of mitosis. Meiosis lowers the chromosome number by half.
Explanation of Solution
The difference between the mitosis and meiosis is given as follows:
Meiosis | Mitosis |
1. It happens in germ cells. | 1. It occurs in somatic cells |
2. It involves crossing over. | 2. It does not involve crossing-over. |
3. It includes two nuclear divisions. | 4. It involves one nuclear division. |
5. The pairing of chromosomes takes place. | 3. No chromosome pairing is seen. |
Meiosis takes place in germ cells and mitosis occurs in somatic cells. Meiosis forms 4 daughter cells which are haploid, but mitosis produces two daughter cells, which are clones.

- 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. 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_forward
