Answer: This helps cells by the DNA telling what the cell to do based on the sequence.
Explanation:
Answer:
Mother - XAXA
Father - XY
Explanation:
Please see the attached image - complete question
Solution -
In the second cross the female is affected while the male is unaffected
The disease mentioned in the question is dominant X inked which means even one X chromosome can cause the disease. Thus, it will impacts males more than females.
Let the allele representing a diseased X gene be XA
and the allele for normal X gene be X
The offspring have all diseased males, which means that the genotype of affected female will be XAXA
And the genotype of unaffected male will be XY
The gene mutation is a permanent adjustment in the DNA sequence that can replicate but differ from another.
<u>Explanation:</u>
There is a constant change of DNA in the process of gene mutation, the gene mutation is a permanent adjustment in the DNA sequence that can replicate but differ from another.
Mutations can take the form of anatomy and deletions, creating a wide variety of lengths known as indels. This insertion and deletion in the sequence of nucleotide is called frame shift mutation.
This result comes out as a complete alteration of amino acid sequence. The who mRNA sequence would be read differently and produce a different kind of amino acid which produces polypeptide chain.
Answer:
The correct option is<u> B. The original Dutch colonists just happened to carry the gene for Huntington's disease with unusually high frequency .</u>
Explanation:
In biology, the founder effect is a term which is used to describe the loss of genetic variation in a small population which has migrated from its larger population. No matter what the original, larger population looked like, the migrated, smaller population will have lesser variations. As a result, the small migrated population will have a completely different genotype as well as phenotype from the original population.
For example, In the above-mentioned question, the original Dutch colonists had an abundance of the genes for Huntington's disease. Hence, it was transferred to the Afrikaners from them as they had very fewer variations.
Answer:
so that whenever we get hurt or something happens our system can grow back like a scar.Everyday it is rebuilding new cells as well as it is always throwing away cells that don't work anymore
