Pooja has green eyes while her parents and brother have black eyes. Pooja’s husband Ravi has black eyes whil his mother has green eyes and his father has black eyes.
On the basis of the above given information, is the green eye colour a dominant or a recessive trait? Justify your answer.
What is the possible genetic makeup of pooja’s brother’s eye colour?
50% of the offspring of Pooja’s brother are green eyed.with the help of cross show how this is possible.
Answers
The green eye color is a recessive trait because Pooja's parents and brother have black eyes, and recessive traits are expressed only in homozygous (parents are heterozygous). The possible genetic makeup of Pooja’s brother’s eye color is homozygous dominant AA or heterozygous Aa.
What is a homozygous dominant individual?A homozygous dominant individual is one that has a domain allele by duplicated instead of another allele for the same locus. In a heterozygous individual, the dominant allele masks the expression of the recessive allele that causes the trait such as occurs in green eyes that are expressed in recessive homozygous individuals.
In the cross here we can be denoted the domain black eye alle as 'A' and the recessive green eye alle as 'a', thereby the cross between heterozygous parents is:
A a
A AA Aa
a Aa aa
Therefore, with this data, we can see that the green eye color is recessive.

Many organisms live in intertidal areas. However, fewer organisms live on high, rocky shores than in other intertidal environment. What are the probable reason for this?
Answers
Answer:
The intertidal zone or area is defined as the area where the ocean and land meets between high and low tides.
Many of the organisms live in intertidal areas while fewer organisms live on high rocky shores because of the adaptation ability of the organisms.The probable reasons for this can be:
Intertidal zones have frequent changes in temperature, moisture, and salinity, some animals evolve them and migrate to rocky shores.Some animals include adaptive features such as attaching more firmly to the rocks along with resistant shells, restricting activities and the ability to retain water helps them to survive in rocky shores.Most of the animals are unable to withstand to the sun for most of the day as in rocky shores, so they prefer to live in intertidal zones.Animals living in rocky shores depends on the floating water that carry food for them.Example of animals living in intertidal zones are brittle stars, barnacles, crabs and other.
Example of animals living in rocky shores are sponges, mussels and sea squirts et-cetra.
Hence, the animals evolve some adaptive feature that allow them to migrate to rocky shores.
Create the mRNA strand and the amino acid chain that would be produced during protein synthesis.
AAA-GCT-CCA-TCG-GCT-AGG (DNA)
Answers
To determine the mRNA strand and the resulting amino acid chain during protein synthesis, we need to transcribe the given DNA sequence into mRNA and then translate it into amino acids using the genetic code. These are fundamental steps that both occur during synthesis of protein.
Given the DNA sequence: AAA-GCT-CCA-TCG-GCT-AGG
1. Transcription:
During transcription, DNA is converted into mRNA. We create the complementary mRNA sequence by replacing each DNA base with its corresponding RNA base:
AAA-GCT-CCA-TCG-GCT-AGG (DNA)
UUU-CGA-GGU-AGC-CGA-UCC (mRNA)
2. Translation:
During translation, mRNA is decoded to produce an amino acid chain based on the genetic code. Each set of three mRNA bases, called a codon, corresponds to a specific amino acid. Here's how the mRNA sequence is translated into amino acids using the genetic code:
UUU | CGA | GGU | AGC | CGA | UCC (mRNA)
Phenylalanine-Arginine-Glycine-Serine-Arginine-Serine (we must look at a codon table to interpret what amino acids are corresponding)
Answer:
Therefore, the mRNA strand produced from the given DNA sequence is UUU-CGA-GGU-AGC-CGA-UCC, and the resulting amino acid chain during protein synthesis is Phenylalanine-Arginine-Glycine-Serine-Arginine-Serine.

although 2 cells valled gametes fuse, the product formed is a single cell called zygote . justify
Answers
Although 2 cells called gametes fuse, the product formed is a single cell called a zygote. The product formed is a single-celled zygote.
Sperm and egg cells merge during the fertilization process. To create the zygote, the sperm cell's contents are transported into the egg. Because of this, a single-celled zygote is the end result.
A zygote is the result of the fusion of an egg cell and a sperm cell, sometimes referred to as a fertilized ovum or fertilized egg. In the days after conception, the zygote quickly divides from a single cell at first. The 46 chromosomes required are all present in the zygote's single cell, which receives 23 from the sperm and 23 from the egg.
zygote, the fertilized egg cell produced when a female gamete (egg, or ovum) and a male gamete combine (sperm). The zygote stage is short and is followed by cleavage, when the single cell divides into smaller cells, in the embryonic development of humans and other animals.

which action must take place before transcription can begin?
Answers
Before transcription can begin, a process known as DNA unwinding and unzipping must take place.
Transcription is the process by which genetic information encoded in DNA is copied into a complementary RNA molecule. However, before transcription can occur, the DNA double helix must undergo unwinding and unzipping.
During DNA unwinding, the hydrogen bonds between the complementary nucleotide bases (adenine, thymine, cytosine, and guanine) are broken, causing the DNA double helix to separate into two strands. This separation exposes the DNA template strand, which serves as a template for RNA synthesis.
Once the DNA strands are unwound, the process of DNA unzipping occurs. Enzymes, such as helicase, help in separating the DNA strands by breaking the hydrogen bonds between the base pairs.
As a result, the DNA molecule is "unzipped" into two separate strands, with the template strand serving as a template for RNA synthesis.
After DNA unwinding and unzipping, the stage is set for transcription to begin. The RNA polymerase enzyme can then bind to the DNA template strand and initiate the synthesis of an RNA molecule using complementary RNA nucleotides.
Thus, DNA unwinding and unzipping are essential steps that precede the initiation of transcription.

If your immune system can’t actually stop you from getting ill, then why is it beneficial? Why do you think it evolved to work this way, instead of simply stopping every infection in its tracks?
Answers
Answer:
Your immune system fights off infection and disease. It has a number of ways to detect and destroy anything it recognizes as foreign to your body, including bacteria, viruses, fungi, parasites or unhealthy cells such as cancer cells. In some people, the immune system goes into overdrive, causing the body to see its own cells as foreign and attack them. This leads to what we call autoimmune diseases, such as Crohn’s disease, rheumatoid arthritis and lupus.
