How does replication of the lagging strand of DNA compare with replication of the leading strand?
Natali5045456 [20]

Answer: The correct answer is- B) Okazaki fragments are made on the lagging strand but not on the leading strand.

DNA replication is a biological process in which two identical replica of DNA are produced from single original DNA molecule through an enzyme called DNA polymerase.

The strands of double helical DNA are first separated ( with the help of helicase enzyme) so that the template DNA strands are exposed. DNA is synthesised in 5' to 3' direction.

Leading strand ( whose template strand is 3' to 5') is synthesized in continuous manner as DNA polymerase moves along the direction of replication folk.

Whereas lagging strand ( whose template strand is 5' to 3') is synthesized in a discontinuous manner as it requires multiple primers to synthesise the DNA. It generates small fragments of DNA called okazaki fragments.

Fruit production in anthophytes develops from: a. a female reproductive structure b. a male reproductive structure c. both male
Fed [463]

Answer:

a. a female reproductive structure

Explanation:

Reproduction can be defined as a biological process which typically involves living organisms producing an offspring.

Basically, there are two (2) methods of reproduction and these are;

I. Sexual reproduction: it involves the combination of the genome (gamete) of a male and female living organism during fertilization.

II. Asexual reproduction: it involves the cloning of a living organism to produce an offspring because there is only a single parent.

Antophyte is the division name for flowering plants and they are considered to be the most successful of all the other division of plants in terms of reproduction.

Division Antophyta are classified into two (2) main categories and these includes;

I. Monocot: this group of flowering plants have a single cotyledon. Some examples of monocots are lilies, corns, grasses etc.

II. Dicot: this group of flowering plants have two cotyledon. Some examples of dicots are beans, peas, peanuts, etc.

Basically, fruit production in anthophytes develops from female reproductive structure known as the ovary. Once the ovary is fertilized by a sperm, they ripen into a fruit.
