Genetic Map + distances between genes

---T--------------S---------------N---

   ║---6.4%---║----16.3%---║

   ║-----------22.7%-----------║

Explanation:

Available data:

We can recognize the parental gametes in the descendants because their phenotypes are the most frequent,

while the double recombinants are the less frequent.

And simple recombinant gametes produced by the cross, which frequencies are intermediate.  

Comparing the parental and the double recombinant we will realize that they only change in the position of the alleles S. This suggests that the position of the gene skin texture is in the middle of the other two genes, because in a double recombinant only the central gene changes position in the chromatid.

---T-----S-------N---

Now we will call Region I to the area between T and S and Region II to the area between S and N.

---T------S-------N---

      RI      RII

Once established the order of the genes we can calculate distances between them, and we will do it from the central gene to the genes on each side. First We will calculate the recombination frequencies, and we will do it by region. We will call P1 to the recombination frequency between T and S genes, and P2 to the recombination frequency between S and N.

P1 = (R + DR) / N

P2 = (R + DR)/ N

Where: R is the number of recombinants in each region, DR is the number of double recombinants in each region, and N is the total number of individuals. To calculate the recombination frequency, we have to know that 1% of recombinations = 1 map unit = 1cm. And that the maximum recombination frequency is always 50%.  

N = 151 + 33 + 11 + 2 + 155 + 29 + 12 + 0 = 393

So:

Now, to calculate the recombination frequency between the two extreme genes, A and B, we can just perform addition or a sum:

P1 + P2= Pt

0.064 + 0.163 = Pt

0.227 = Pt

The genetic distance will result from multiplying that frequency by 100 and expressing it in map units (MU).  One centiMorgan (cM) equals one map unit (MU). The map unit is the distance between the pair of genes for which one of every 100 meiotic products results in a recombinant product.

Answer: 1. The nitrogen cycle is a biogeochemical cycle.

2. The carbon cycle is a biogeochemical cycle.

Explanation:

1. The nitrogen cycle can be defined as the biogeochemical cycle in which the atmospheric nitrogen is utilized by the plants which is fixed by the soil bacteria. The nitrogen becomes the part of the biosphere as plants utilize it as an important development mineral. The nitrogen cycle involves the nitrogen fixation in which plants fix nitrogen by the help of bacteria into ammonia, nitrification in which the ammonia is converted into nitrite, nitrogen assimilation in which the plants assimilate and utilize the nitrogen for their growth and development, and denitrification involves the reduction of nitrite into atmospheric nitrogen. The conversion of nitrogen is carried out via physical and biological processes.

2. The carbon cycle involves the atmospheric carbon dioxide being circulated in plants as they utilize it for photosynthesis. The carbon dioxide is fixed by the plants in the form of carbohydrate which is consumed by the animals and on decomposition of plants and animals dead matter release carbon dioxide gas to the atmosphere. This allows the recycling of the carbon dioxide gas in the environment.

FALSE. X-rays and gamma rays are examples of ionizing radiation, but they do not cause the formation of thymine dimers.

Thymine dimers are a type of DNA damage that occurs when two adjacent thymine bases in DNA become covalently linked to each other, forming a dimer. This can occur when DNA is exposed to ultraviolet (UV) radiation from the sun or other sources. The formation of thymine dimers distorts the normal structure of DNA, causing errors during DNA replication and transcription, which can lead to mutations, cell death, or cancer. Thymine dimers are one of the most common types of DNA damage caused by UV radiation, and they play a significant role in the development of skin cancer.

UV radiation has a shorter wavelength than X-rays and gamma rays and is non-ionizing, meaning it does not directly ionize molecules. Instead, UV radiation causes chemical reactions in molecules, including the formation of thymine dimers in DNA.

Answer: B. RNA to DNA

Explanation:

RNA to DNA mode of information transfer usually does not occur in a working human, plant or bacterial cell. The correct option is B.

Thus, Each human cell has two copies of the genetic material, which is spread among 23 pairs of chromosomes in the nucleus of each cell.  

The human genome refers to all of this. There are about 30 000 genes in the human genome, and each one codes for a protein.

The human genome has long regions of transcribed DNA that do not code for proteins. Around 95% of the genome is made up of what are known as introns. Although the human genome's nucleotide sequence is now rather well established, we still don't fully comprehend why the majority of it is non-coding.

Thus, RNA to DNA mode of information transfer usually does not occur in a working human, plant or bacterial cell. The correct option is B.

The inter-relationship between genetics and evolution lies in the fact that genetics provides the raw material for evolutionary change. Genetic variations drive phenotypic diversity, which is shaped by natural selection, driving species adaptation and evolution.

Genetics and evolution are closely intertwined fields of study. Genetics focuses on the study of genes, heredity, and genetic variation, while evolution examines how species change and diversify over generations. The relationship between the two lies in the role genetics plays in driving evolutionary processes.

In summary, genetics provides the genetic variation that fuels the process of evolution. Genetic variations are subject to natural selection, resulting in the adaptation and diversification of species over time. The interplay between genetics and evolution is crucial for understanding the mechanisms driving biological diversity and the history of life on Earth.

Genes

Pedigrees have multiple uses. One of them is getting to know an individual's genotype. In the e xposed example, the individual IIIb is X-Y.

A Pedigree is the representation of a family's history. This graph is used to track a trait through different generations, and analyze the inheritance pattern of a particular gene and its expression.

It is a tool used to understand how genes are transmitted from the parental generation to the descendants, and what are the probabilities of  inheriting them.

In sex linked inheritance, we need to remember that the gene coding for the trait is linked to the sex-chromosome (in this case, the X-chromosome).

In pedigrees, usually affected individuals or individual carring the trait are representes with solid black figures.

Individual IIIb is a black square, meaning it is an affected man. Its genotype is X-Y. The X-chromosome is carrying the recessive allele (-).

In the attached files you will find the pedigree with the genotype of each member of the family. Notice that individuals X+X represent either homozygous dominant or heterozygous females.

In the given scenario, the water will move from cell to the outside, resulting in decrease in cell size. The correct option is A.

If a container has a cell with a 10% salt solution and 90% water, and the outside concentration is 30% salt and 70% water, osmosis will occur.

Osmosis is the movement of solvent molecules (in this case, water) across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

In this scenario, the cell has a lower salt concentration (10%) compared to the outside environment (30%).

As a result, water molecules will move from the area of lower salt concentration (inside the cell) to the area of higher salt concentration (outside the cell) in an attempt to equalize the solute concentration on both sides of the membrane.

Thus, the correct option is A.

Answer:

An mRNA molecule

Explanation:

Transcription is a process by which the information stored in a specific fragment of DNA called 'gene' is used to produce a complementary RNA molecule, usually a messenger RNA (mRNA). Subsequently, this mRNA is used as template to produce a polypeptide chain (i.e., a sequentially ordered amino acid chain) through the process of translation. A stop codon, also known as termination codon, is a triplet of nucleotide bases within an mRNA that signals the end of the protein when it is synthesized in the ribosome. There are three stop codons (UAG, UAA, and UGA) that are capable of stopping protein synthesis.
