Answer:
The life cycle of plants is composed of sporophye generation and gemetophyte generation. They show alternation of generation in which gametophytr produce gametes that develop into sporophytic plant. Sporophye produce spores that develop into gametophyte plants.
Example:
Bryophytes, pinus etc
Answer: Option B) each parental strand serves as a template for the synthesis of a complementary strand
Explanation:
In semi-conservative DNA replication,
- a parent double-stranded DNA splits in two.
- Each strand is then read by the enzyme, DNA polymerase, to ensure accurate replication of a newly synthesized strand
- the new strand contains nucleotides that are complimentary to free nucleotides present in the parent strand.
Thus, option B perfectly describes semi-conservative replication of dna
Answer:
Mutation
Explanation:
A mutation is a change in the sequence of genetic letters, called bases, within a molecule of DNA.
