2. Write full form of DNA and RNA. Where is DNA found in a cell?
3. What is the number of chromosomes in human being? What are genes and where are they located?
4. Write any two functions of nucleus.
Answers
Answer:
prokaryotic cell they are generally small in size material is undefined a single chromosomes present cell organelle leaves are absence ribosomes are seventies types
eukaryotic cells they are comparatively large in size through necklace is present having nuclear membrane more than one chromosome present cell organelles are present ribosomes are 80 type
2 full form of DNA is deoxys deoxyribonucleic acid
Dna is liquid located in the both nucleus of plants and animal cells
Answer:
1. There are several differences between the two, but the biggest distinction between them is that eukaryotic cells have a distinct nucleus containing the cell's genetic material, while prokaryotic cells don't have a nucleus and have free-floating genetic material instead.
2. The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material found in all living organisms, ranging from single-celled bacteria to multicellular mammals. It is found in the nucleus of eukaryotes and in the chloroplasts and mitochondria
3. The human genome has 23 pairs of chromosomes located in the nucleus of somatic cells. Each chromosome is composed of genes and other DNA wound around histones (proteins) into a tightly coiled molecule. The human species is characterized by 23 pairs of chromosomes, as shown in Figure below.
4. This organelle has two major functions: it stores the cell's hereditary material, or DNA, and it coordinates the cell's activities, which include growth, intermediary metabolism, protein synthesis, and reproduction (cell division). Only the cells of advanced organisms, known as eukaryotes, have a nucleus
