Answer:
The correct answer to the question is: 1) free in the cytoplasm.
Explanation:
- Ribosomes are responsible for synthesising polypeptide chains by the process of translation from mRNA or messenger Ribonucleic Acid.
- They are found free in the cytoplasm or remain bound to the Endoplasmic Reticulum (ER) to form the Rough Endoplasmic Reticulum (RER).
- The cytoplasmic proteins are synthesised by the free ribosomes.
- The membrane proteins, secretory proteins and the organelle specific proteins are synthesised by the Ribosomes located on the Endoplasmic Reticulum.
- This is because these proteins need to be translocated to the target organs through vesicles that buds out of the ER and and the Golgi bodies.
- As the luciferase polypeptide is located in the cytoplasm, it is synthesised by the free ribosomes present in the cytoplasm.
The correct answer is B) City B because it is a wet region and the temperature fluctuates around the freezing point
City B rocks are likeliest to experience frost wedging because its temperature fluctuates between 5°C to -4°C . Fluctuation of temperature near freezing point, frost wedging takes place when water converted into ice. Water expands when it changed in ice. As a result water continually seeps into rock cracks. The frequent freezing and melting causes Freeze-thaw. Through repeated melting and freezing of water the rocks break apart.
It is only DNA which contains sugar deoxyribose, has primary function storing, transferring genetic information and double-stranded. RNA it only directs code for amino acid which contains the uracil base and it is found throughout the cell.
Both the DNA and RNA are polymers which are made up of nucleotides and contains the adenine base.
Answer:
Option B, After Dried
Explanation:
All biological fluids such as blood, semen, saliva etc. are not collected from the crime scene when they are wet or moist. Since, we all aware that all human beings are genetically distinct hence if these fluids are tested after they dry up, no specific impact can occur on the sample and the test result. Also collecting dry sample is much easy and comfortable. The dried samples undergo DNA analysis there by producing a genetic profile which is specific to individuals
Hence, option A is correct
