Answer:
C.
Explanation:
Human reproduction is any form of sexual reproduction that results in fertilisation by humans. It normally includes a man and a woman having sexual intercourse. During sexual intercourse, the contact between male and female reproductive systems leads to the woman's ovum being fertilised by the man's sperm.
In human fertilization, a hapoloid ovum is released that fuses with a haploid sperm and produces a single 2n diploid cell called the zygote.
Hence, the correct option is C.
Answer:
The three processes from left to right are:
<u>Replication</u> DNA <u>Trancription</u> RNA <u>Translation</u> Protein
Explanation:
The process in question in the diagram is called the central dogma of life which describes the flow of genetic information from DNA to RNA to Protein. The three processes involved are:
- DNA Replication
- Transcription
- Translation
DNA Replication:
DNA replication is the process by which DNA makes a copy of itself. Replication of DNA is semi-conservative. this means that each new helix is a combination of an old (parent) strands and a new (daughter strand). The parental strand is used as a template to generate a complementary daughter strand.
Transcription:
Transcription is the formation of an RNA transcript of the DNA template. This process yields a mRNA that is further used as a code to manufacture proteins in the process of translation.
Translation:
Translation decodes the mRNA formed in transcription to generate proteins with specific amino acid sequence.
Answer:
The correct answer would be 37.
Egg or sperm or gametes are cells produced by the process of meiosis and carry half the number of chromosome (n) present in a parental cell (2n).
Meiosis is a type of cell division which results in the formation of four daughter cells each having exactly half the number of chromosome present in parent cell.
The sperm unite or fertilize with egg which restore the chromosome number (2n) in the zygote.
