marissa [1.9K]

Answer:

The correct answer is option - A. Gametophyte, C. spore, and D. sperm.

Explanation:

The egg cell of a plant is haploid in the cell which means it has only one set of chromosomes. The haploid cells arise from the meiosis cell division in parent sex cells. These parent cells are divided into four cells with half of the chromosome number in comparison to the parent cells.

The gametophyte, spore, and sperm all three are the product of the meiosis division and are haploid in number.

Thus, the correct answer is option - A, gametophyte, C. spore and D. sperm.

HACTEHA [7]

mRNA (Messenger RNA) is translated by ribosomes and contains the code that specifies the sequence of amino acids in polypeptide chain.

A single-stranded ribonucleic acid molecule is known as messenger RNA(mRNA) plays a major role in translation.

Translation is the method by which an mRNA codes for a certain protein. mRNA provides the template for protein synthesis.

The ribosome translates the mRNA that is produced from the DNA into a chain of certain amino acids and protein synthesis is facilitated by this amino acid sequence.

The genetic code, which connects the DNA sequence to the amino acid sequence of proteins, is used to "read" the mRNA. Each group of three nucleotides in mRNA forms a codon, and each codon corresponds to a particular amino acid (triplet code).

Thus mRNA contains the code that specifies the sequence of amino acids in a polypeptide chain.
