Answer:
3) Fertilization membrane.
Explanation:
When sperm cell fertilizes an egg cell, signal transdution occurs which causes fertilization membrane to be formed. Ovum thickens and hardens the vetelline membrane causing separation and prevents multiple fertilization by the spermatozoon.
Answer:
Option C
Explanation:
Primase synthesizes DNA polymerase through the initiation of synthesis of RNA primer. DNA polymerase is able to add nucleotides in only one direction towards the direction of replication fork Hence, it add to the chain only at 3’ end and build new strand from 5’ to 3’ end.
The 5’ to 3’ strand is the leading strand and is easy to build as 5’ to 3’ progresses towards the replication fork and DNA polymerase also move in the same direction
Hence, option C is correct
D because my freind said so
The transcription process is the formation of mRNA from the DNA. Hence the product of the transcription process is mRNA. The translation process is the formation of protein molecule from the mRNA. Hence the product of the translation process is the proteins.
