Explanation: Fritz Miescher was a Swiss physician. He reported discovering the DNA molecule in the cell's nucleus in 1868. This created speculation that the DNA might have something to do with genetics
Answer:
Ở đậu Hà Lan, A- thân cao, a-thân thấp. Cây thân cao giao phấn với cây thân cao — F1 có tỷ lệ 900 thân ca0:299 thân thấp — tỷ lệ 3:1 — cây thân cao có kiểu gen dị hợp Aa. Tỷ lệ F1 tự thụ phấn cho cho F2 toàn cây thân cao → F1 đồng hợp AA → chiếm 1 phần 4
P: Aa x Aa → 1 phần 4 AA: 2 phần 4 Aa: 1 phần 4 aa
Answer:
Explanation:
1.A deletion mutation occurs when a wrinkle forms on the DNA template strand and subsequently causes a nucleotide to be omitted from the replicated strand.
2.This type of variant results in a shortened protein that may function improperly, be nonfunctional, or get broken down. An insertion changes the DNA sequence by adding one or more nucleotides to the gene.
3. A substitution mutation can cause the following: Change in the coding of amino acids codon to a particular stop codon resulting in an incomplete protein, which is usually non-functional. Can cause Silent mutations where a codon change can encode the same amino acid resulting in no changes in the protein synthesized.
4. when a premature nonsense or stop codon is introduced in the DNA sequence. When the mutated sequence is translated into a protein, the resulting protein is incomplete and shorter than normal. Consequently, most nonsense mutations result in nonfunctional proteins.
Answer:
the answer is D which is CJD
Biochemistry because it does not have to do with the erosion
