Diploid

Further explanation

Diploid is a term for a cell or individual that has cells with two sets of genomes. Each genome in a cell is paired with a homolog based on the length of the chromosome. Diploid cells are formed from the fertilization of haploid gamete cells. Haploid gamete cells fuse so that the chromosomes mix in one cell to form diploid cells. In sexual reproduction gametes produce offspring that carry genetic traits from the fusion of these gametes (commonly known as male gametes and female gametes) The number of haploid cell chromosomes is abbreviated (n), while diploid (2n) because it is a multiple of the basic chromosome set or female gametes. called euploid polyploid. The diploid cells can divide into other diploid cells through the process of mitosis and forming somatic structures. This can occur because the chromosomes replicate before the cell divides. Through mitosis the cell will maintain the set number of chromosomes so that the newly formed cell has the same number of chromosomes as the original cell chromosome.

Diploid cells can produce cells that are haploid by the process of meiosis to form gamete cells. These events continue to occur through the process of reproduction and fertilization to form a continuous cycle if the individual continues to grow and multiply.

Answer:

Diploid.

Explanation:

DNA is present in the genetic material of all the eukaryotic and prokaryotic organisms.The eukaryotic genome contains DNA wraps around the histone proteins. Multiple distinct chromosomes are present in the eukaryote genome.

The eukaryotic genome are generally linear structure with the two copies of each chromosome. This makes the eukaryotic genome as diploid structure.

Thus, the correct answer is option (1).

What are the mRNA triplets coded for from this gene?

A) GGG UUC ACC

RNA codons determine certain amino acids, so the order in which the bases occur within in the codon sequence designates which amino acid is to be made bus with the four RNA nucleotides (Adenine, Guanine, Cysteine and Uracil). Up to 64 codons (with 3 as stop codons) determine amino acid synthesis. The stop codons ( UAG UGA UAA) terminate amino acid/ protein synthesis while the start codon AUG begins protein synthesis.

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is condensed and tightly wound around histones as chromosomes. Chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase, to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes.

Nucleic acids like DNA stores all of an organism’s genetic information. Nucleic acid molecules comprise the nitrogenous bases Guanine, Adenine, Cytosine and Thymine. Conversely, RNA nucleotides are Adenine, Guanine, Cysteine and Uracil. These pair up as base pairs due to their varied structure- largely influenced by the location of N molecule.

In certain combinations, these bases form codons which act as instructions for protein synthesis. Codons are three nucleotide bases encoding an amino acid or signal at the beginning or end of protein synthesis. Thus, these contribute to the broad diversity of living organisms, as varied combinations of these 64 codons can produce many proteins which can be organized into cells, tissues and organisms.
