Autism, Schizophrenia, leukemia,
could you give me brainliest if correct?
We have been given that different tissue samples are in their respective stage of cell cycle.
Ans is option B because cancerous cells tend to divide indefinitely regardless of the presence or absence of growth factors. In cancerous cells G0 check points fail and the cells are always in some stage of mitosis i.e. cell is supposed to be in any of the following stages of mitosis :
1) Prophase
2) Metaphase
3) Anaphase
4) Telophase
Answer:
The correct answer would be C. The protein synthesized will contain many erroneous amino acids since the loss of one base will shift the reading of the encoded base sequence.
Deletion mutation that does not occur in the multiple of three bases can results in frame-shift mutation.
It changes the reading frame of nucleotide in DNA. Thus, the reading frame of codons in mRNA would also change.
Consequently, the sequence of amino acids in a polypeptide chain would change or alter. Thus, a protein would contain many erroneous amino acids.
An example of the same is shown below in the image.
I think a frameshift mutation that occurs very early in a protein sequence would have an effect on the structure of the protein such that the primary, secondary, and tertiary structures would be altered. A frameshift mutation occurs when a protein is drastically altered because of an insertion or a deletion. Insertions and deletions cause a change in the length of a gene, which causes a shift in the codon reading frame.

Answer:</h2><h2>KAROTYPE:</h2>
This is the picture of karyotype. Karyotype is a collection of a Individuals chromosome. Like pairs are separately represented from the unlike pairs, It is generally used to study the chromosomes and the abnormalities found in the number of chromosomes.
<h2>_____________________________________</h2><h2>CHROMOSOMAL NUMBER 18:</h2>
Every chromosomal pair seems fine, except the chromosomal pair number 18. Because as you ca see that it has 3 chromosomes instead of 2. This impairment in the chromosomal pair is called trisomy as it has 3 chromosomes.
<h2>_____________________________________</h2><h3>TRISOMY 18:</h3>
Trisomy 18 is also called Edwards syndrome. It is a chromosomal condition associated with abnormalities in more than one part of the body. Individuals with trisomy 18 often mature slowly than normal fetus before birth and they have lower weight at the time of birth as compared to the other children.
