Question

Does anyone know what these are in Biology form? like as far as phases

Triple X Syndrome

Turner's Syndrome

color blindness (include what is special about how this is inherited)

Down Syndrome

point mutation

Answer 1

your book probably does.

Answer 2

Triple X syndrome is caused by non-dysjunction during meiosis, the female has 3 X chromosomes instead of 2
Turner syndrome is when a female only gets one X instead of the two needed, it is the result of non-dysjunction
Down syndrome is also a cause of non-dysjunction, its when the 21st chromosome doesn't seperate properly during meiosis and so the child gets three 21st chromosomes instead of 2.
Point mutation is when is like substitution, deletion or insertion. Occurs when a codon (3 nitrogen bases on the mRNA ) is either substituted, deleted or inserted causing a change in the protein produced by the amino acids.

Answer 4

There is a mutation that is known to cause alkaptonuria that changes the arginine at position 330 to a serine. This mutation changes one single position from one base to another. Using the DNA sequence encoding amino acid 330 in HGD and a table of the genetic code, determine which base was changed and what the new base is.
