Answer:
The correct answer is
1. 5' end.
2. guanosine
3. 5′ to 5′ triphosphate linkage.
4. On the 7th position.
5. 2′ hydroxy-groups of the first 2 ribose sugars.
Explanation:
The eukaryotic mRNA is processed or modified with a guanosine cap at 5' end and poly-A tail at 3'end before translation.
The process of adding a cap at 5' end of a growing mRNA is known as capping. The process of capping adds guanosine nucleotide at the 5'-end of mRNAs by 5′ to 5′ triphosphate linkage. This guanosine is modified by methylating at the 7th position of the atom. The mRNA is further modified by methylation of first two ribose sugars at their 2′ hydroxy-groups. This capping is advantageous to the sequence as it protects the end from phosphatases and nucleases.
Explanation:
The label A represents mitochondria.
The mitochondria is also called the powerhouse of the cell which converts glucose to energy rich molecules of ATP.
Label B represents nucleus.
Nucleus contains the genetic material or DNA, RNA , nucleolus, chromatin fibres and proteins. It contains the chromosomes which control the hereditary characteristics.
Label C represents lysosome.
Lysosomes contain digestive juices which breaks down large cell parts and large molecules and helps in intracellular digestion.
Label D represents rough endoplasmic reticulum having ribosomes.
The rough endoplasmic reticulum provides surface for protein synthesis. It is also used to transport cellular contents from one cell to another.
Answer:
How to get enough energy for daily life
Explanation:
All living things need to get energy from food, and finding food is definetly a very VERY big challenge.
Answer:
Unicellular organism
Explanation:
Unicellular organisms are organism that posses only a single cell. They are also referred to as acellular organisms. Some unicellular organisms are prokaryotes while a few of them too eukaryotes.
The major characteristic that describes a plant is the presence of green pigment called chlorophyll within the chloroplast which enables them to synthesize their food by themselves through photosynthesis
Answer:
Urinary system filters your blood, removing waste and excess water.
Your digestive system breaks nutrients into parts small enough for your body to absorb and use for energy, growth, and cell repair.
The immune system is a complex network of cells and proteins that defends the body against infection.
