Which of the following is not a function of mitosis in humans?
- a. repair of wounds
- b. growth
- c. production of gametes from diploid cells
- d. replacement of lost or damaged cells

Introduction:
Mitosis is also called as equational cell division in which chromosomes are replicated and get separated into two daughter cells. During the mitosis the chromosome number remains same (46 chromosomes). Mitosis is important for tissue repair and during cell growth.
Answer to Problem 1SQ
Correct answer:
The production of gametes from diploid cells is not a function of mitosis. Therefore, option c is correct.
Explanation of Solution
Reason for the correct statement:
The mitosis is also called as uniform division. The mitosis takes place only in somatic cells not in germ cells. The meiosis is another type of cell division which takes place in germ cells which involves in the production of gametes.
Option c. is given as “production of gametes from diploid cells”.
The gametes production from diploid germ cells is not the function of mitosis in humans.
Hence, the option c. is correct.
Reasons for the incorrect statements:
Option a. is given as “repair of wounds”.
The repair of wounds is the function of mitosis. So, it is the wrong answer.
Option b. is given as “growth”.
The mitosis helps in the growth of the cell and also helps in cell division. So, it is the wrong answer.
Option d. is given as “replacement of lost or damaged cells”.
The mitosis functions as the replacement of lost or damaged cells. So, it is the wrong answer.
Hence, options a. b. and d. are incorrect.
The mitosis did not function as the production of gametes from the germ cells in humans.

- 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.
