The H-W equilibrium theory states that, considering a diallelic gene, the addition of allelic frequencies equals 1 (p + q = 1) and the addition of genotypic frequencies equals 1 (p² + 2pq + q² = 1). The percentage of the population that is heterozygous (Ss) for the sickle-cell gene is 42%.

The Hardy-Weinberg equilibrium theory states that in populations that are in equilibrium, their allelic and genotypic frequencies remain the same generation after generation.

These populations are not evolving. No evolutive forces or other events that affect their frequencies are acting on them.

Assuming a diallelic gene that codes for a trait,

⇒ Allelic frequencies are represented as p and q,

The addition of the allelic frequencies equals 1

p + q = 1.

⇒ The genotypic frequencies after one generation are

The sum of genotypic frequencies equals 1

p² + 2pq + q² = 1

Now let us answer the question,

Sickle cell anemia is an autosomal recessive disorder, so individuals expressing this phenotype are homozygous recessive, ss.

We need to calculate the frequency of the heterozygous genotype by using the frequency of homozygous recessive individuals.

The genotypic frequency of individuals born with the disorder is 9%, so

q² = 9% = 0.09

So, knowing the homozygous recessive frequency, we will calculate the recessive allele frequency, q.

If q² = 0.09, then q = √q² = √0.09 = 0.3

So the recessive allele frequency is q = 0.3

Now we need to get the dominant allele frequency, and we will get it by clearing the equation p + q = 1

p + q = 1

p + 0.3 = 1

p = 1 - 0.3

p = 0.7

So, the dominant allele frequency is p = 0.7.

The dominant genotypic frequency is p² = 0.7² = 0.49

Up to here, we know that,

With these data, we can calculate the heterozygous genotypic frequency -2pq- by clearing the following equation,  

p² + 2pq + q² = 1

0.49 + 2pq + 0.09 = 1

2pq = 1 - 0.49 - 0.09

2pq = 0.42

Assuming the population is in hardy-weinberg equilibrium, the frequency of heterozygous individuals Ss = 2pq = 0.42 = 42%.

        A process known as "flint knapping," which translates to "to shape by breaking off bits," is used to remove chips or flakes from a piece of fine-grained stone like flint. This produces a huge amount of waste scraps or flakes, much as when you whittle a piece of wood.

        Tools fashioned of flake stone, such as spear points, arrowheads, knives, scrapers, and drills, have sharp edges when shattered.

       The Paleolithic Era : Old Stone Age is another name for the Paleolithic Period, a prehistoric cultural stage or degree of human evolution that was marked by the use of crude chipped stone tools.

       Homo habilis, one of the oldest members of the human family, created the first stone tools during the early Stone Age, which is also referred to as the Lower Paleolithic. These were essentially stone cores that had flake material taken from them to sharpen the edge, making it suitable for use in cutting, chopping, or scraping.

         Hammerstones were employed by early humans in East Africa to pound off sharp flakes from stone cores. Early humans employed these techniques for accessing new resources, including flesh from huge animals, for more than two million years.

Eukaryotic genomes comprise mostly noncoding DNA, whereas prokaryotes have mostly coding DNA. So the correct option is (b).

Prokaryotic chromosomes are found in the nucleoid, while those of eukaryotes are found inside the nucleus. Eukaryotic cells contain a membrane-bound nucleus (as well as membrane-bound organelles), whereas prokaryotic cells have not. This is the primary distinction between the two types of cells.

Prokaryotic genomes have less noncoding DNA compared to eukaryotic genomes, which have a lot of it. Bacteria typically have circular chromosomes, whereas eukaryotes typically have linear chromosomes. Eukaryotes and prokaryotes both have negatively supercoiled double-stranded DNA.

Therefore, eukaryotic genomes comprise mostly noncoding DNA, whereas prokaryotes have mostly coding DNA. So the correct option is (b).

The further apart two genes are the more likely it is that multiple crossovers will occur.

Even if there has been crossing over, the offspring may still have parental genotypes that are not considered recombinants if there is a double crossover (or an even number of crossovers) between two genes. Double crossings will cause the real map distance to be underestimated since genetic maps are constructed by counting visible recombinants in the progeny.

The middle allele is transferred from one sister chromatid to the other during a double-crossover event, which is the following crucial step. As a result, the surrounding genes' parental alleles and the non-parental allele of the middle gene are positioned on the same chromosome.

The protein structure is divided into 4 levels. The primary structure is made up of peptide bonds connecting the amino acid chains. One's N terminus forms a relationship with another's C terminus.

The initial step of folding is secondary structure. The amino acid chain may create structures like the Alpha helix and Beta sheet by hydrogen bonding with itself.

A protein's overall structure is impacted by the polarity of its amino acids. Due to the hydrophilic characteristics of the side chain, polar amino acid residues frequently occur outside of proteins.

The folding and intramolecular bonding of a protein's linear amino acid chain are driven by the protein's fundamental structure, or its amino acid sequence, which ultimately defines the protein's distinctive three-dimensional form.

When multiple amino acids combine to form a protein, each amino acid's special characteristics dictate how the protein folds into its ultimate 3D structure. The protein may carry out a particular job in our cells because of its structure.

Alternative processing of an mRNA primary transcript may result in the formation mature mRNA

When an RNA transcript is first made in a eukaryotic cell, it is considered a pre-mRNA or primary transcript and must be processed into messenger RNA (mRNA).

The primary transcript is modified to form the mature mRNA. Primary RNA transcripts synthesized by RNA polymerase II (mRNA) are modified in the nucleus by three distinct reactions: addition of the 5' cap, addition of a poly-adenylic acid (poly-A) tail, and non-informative introns. Segment excision. During transcription of mRNA in eukaryotes, some sequences are excised from the primary transcript and the remaining sequences are joined. This processing of mRNA is called splicing. Alternative splicing of precursor mRNAs is an essential mechanism for increasing the complexity of gene expression and plays an important role in cell differentiation and organismal development.
