Proteins are large biomolecules that are made up of long chains of building block molecules called amino acids. Each amino acid folds to form a protein with a specific cellular function. Nucleic acid is basically DNA & RNA. DNA is the genetic information that contains all the information one needs to live. RNA stands for ribonucleic acid and has a variety of roles. When comparing them, they actually don't look at all similar when looking at the large molecules or the 'building blocks'. But, they're both made up of mostly carbon, nitrogen, hydrogen and oxygen. The elements mentioned are assembled in different ways for both Proteins & Nucleic acid. The major similarity between them is that with the protein production DNA and RNA contains all the information that a cell uses to make protein.
Point mutations can show three different types of effects:
- Base substitutions can be silent mutations in which the changed codons correspond to the same amino acid.
- Base substitutions can be missense mutations where the changed codon corresponds to a different amino acid.
- Base substitutions can be nonsense mutations in which the altered codon corresponds to the stop signal.
<h3>What are point mutations?</h3>
Point mutations are changes to the N base of DNA or RNA. Point mutations are common, but their effects can be mitigated by gene recovery mechanisms.
The cause of this point mutation is due to 4 factors:
- Errors during DNA replication by mutagens.
- Breaking of oxygen-phosphate bonds.
- Substitution of base pairs.
- Changes in the number of bases.

Answer:
Independent assortment of chromosomes and hence alleles at Prophase 1 and Anaphase 1 of meiosis ;e<u>nsured that chromosomes of alleles undergo variation at meiosis with random distribution of genes.</u>
The random mating and fusion ensured that random fertilization of gametes take place <u>for the new offspring to inherited varied genetic material from both parents. Therefore they inherited traits which made them different from both parents.</u>

FULL QUESTION
During meiosis, homologous chromatids exchange genetic material by a process called crossing over. This process increases genetic variation in the gametes that are produced.
The figure shows the type of meiotic processes and fertilization for animals. Gametes fuse together in the process called fertilization and form a diploid zygote, which develops into diploid multicellular organism through a series of mitotic divisions. Then meiosis occurs in organism's cells and produces haploid gametes and the cycle repeats. The figure shows the type of meiotic processes and fertilization for plants and some algae. Haploid gametes fuse and form a diploid zygote, which develops into diploid multicellular organism or sporophyte through a process called fertilization. The cells of sporophyte undergo meiosis and form haploid spores. Spores grow into haploid multicellular organism called gametophyte, which produce haploid gametes through mitosis and the cycle repeats.
Which of the following explanations of other meiotic processes and fertilization would also increase variation within a population
