Answer:
During the gap between DNA synthesis and mitosis, the cell will continue to grow and produce new proteins. At the end of this gap is another control checkpoint (G2 Checkpoint) to determine if the cell can now proceed to enter M (mitosis) and divide.
The best and most correct answer among the choices provided by your question is the fourth choice or letter D. Reptiles are the most critically endangered animal group. Their population is threatened due to illegal activities done by man like poaching.

Hi Geny!
Question - Describe the cell theory and the developments that led to the cell theory.
Answer:
There are 3 main components of cell theory:
- Each and every organism is wither unicellular or multicellular.
- The basic unit of life is the cell.
- Cells are created from cells that had existed previously.
There were 3 scientists that made cell theory each of the 3 components of above were the 3 scientists.
- Mathia Schleiden discovered that plants were made of mainly cells.
- Rudolf Virchow discovered that cells are created from calls that had existed previously.
- Theodore Schwann discovered that animals were also made of mainly cells.
Hope This Helps :)
Proteins are polymers of amino acids. There are a fixed set of amino acids that are involved in the making of a protein. These amino acids are varied in number and type to give rise to different combinations in a polymer. This creates a diversity of protein molecules.
The amino acids link to other amino acid in the polymer through the formation of a peptide bond between them. It forms when the carboxylic group of one amino acid molecule reacts and binds to the amino group of the other molecule.
Explanation:
As we know that different versions of the gene are called as the alleles. Allele is the various sequence of DNA (deoxyribonucleic acid) or alleles are known to be different forms of the genes, which can be seen at the same locus on the homologous chromosomes. Let us know assume that gene Tyx has two alleles in it, which represents the two forms of expression having same character. i.e. Tallness and Dwarfness TT(tall), Tt(tall), tt(dwarf). In the given question, the version
(a) TT, where alleles exist in the homozygous dominant conditions,
(b) Tt, where alleles exist in the heterozygous dominant condition
(c) tt, where alleles exist in homozygous recessive condition. Therefore, it might follow autosomal dominant inheritance, or autosomal recessive inheritance or incomplete dominance etc.
