Explanation:
The concentration of carbon dioxide in the atmosphere has increased in the last 200 years. The extra carbon dioxide is causing an enhanced greenhouse effect greater than would happen naturally.
Answer:
The student is wrong, spermatozoa are germinal cells and therefore mitochondrial mutations (likewise genomic nuclear mutations) are inherited by offspring
Explanation:
Although the probabilities of inheriting a mutation from a single sperm cell are low, it since an organism produces millions of sperm cells throughout its life span, the mutations in the germinal cells (i.e., sperms and ovules) are inherited by offspring
Answer: The correct answer is B) Frameshift mutation.
The given mRNA sequence is GGU-GCU-CCU-AUU. When a nucleotide is added at the fourth location in the chain, it entirely changes the frame from the insertion of the nucleotide till the end of the gene sequence. This is called a frameshift mutation.
This is because after adding a nucleotide, a new frame is generated that will code for different amino acids and therefore a different protein will be synthesized.
On the contrary, chromosomal mutation is an abnormality in the chromosome ( in terms of number or structure) whereas substitution mutation is the one, which exchanges one base with another. Deletion of base also results in the frame-shift mutation.
