Answer:
1) c. five
2) a. lysine and arginine
3) g. two
4) d. four
Explanation:
A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Basically, nucleotide comprises of the following parts;
1. Nitrogenous base: this includes adenine (A), thymine (T), guanine (G), and cytosine (C) which are mainly found in the DNA while adenine (A), guanine (G), uracil (U) and cytosine (C) are found in the RNA.
2. A phosphate group.
3. A penrose sugar: it is either deoxyribose in DNA or ribose in RNA.
The two parts or chemical components of a nucleotide which do not change throughout the structure of DNA are;
I. Five-Carbon Sugar also known as deoxyribose and it has hydrogen on its second carbon.
II. Phosphate: this is the structural backbone that provides support to DNA.
Histones are a group of highly basic proteins that are mainly associated with deoxyribonucleic acid (DNA) in the nucleus of a living organism and then condense it to chromatin.
Histones include five main classes of relatively small basic proteins containing relatively large amounts of lysine and arginine. Nucleosomes are made of two each of four types of histones.
Answer: I’m not sure but it relates to natural selection because the rodents depend on the tree for survival and the tree is neither harmed or benefited from the rodents the cause and affect is the rodents stay in the tree and the tree is neither harmed or benifited. Pls do not rely on my answer I’m just saying what I think
Explanation:
Because if not u would not be who u are
Answer;
D. identical, diverse
Daughter cells produced when cells undergo mitosis are genetically identical, and daughter cells produced when cells undergo meiosis are genetically diverse.
Explanation;
Meiosis and mitosis are the two major types of cell division. Mitosis takes place in the somatic cells (body cells) in which parent cells undergo division to yield daughter cells that have similar number of chromosomes as the parents. Meaning the daughter cells are identical to the parent cells in terms of genetic material composition.
Meiosis on the other hand, involves division in the germ-line cells in which parent cells divides to yield daughter cells that contain half the number of chromosomes as the parent, meaning that they are not genetically identical, however they re genetically diverse due to the process of crossover and recombination.
