The term DNA stands for deoxyribonucleic acid and contains genetic information in its double-stranded helical structure.
Explanation:
A nucleotide can be said to be the basic building block of the DNA molecule. Each of these nucleotides is composed of three components:
- A phosphate group
- A sugar group
- A nitrogen base
The genetic code contained within the DNA is determined by the sequence/order in which these bases occur.
The DNA backbone is made up of the sugar-phosphate nucleic acids framework. These groups occur in an alternating manner, in repeating patterns.
The structure of DNA is fairly regular, as in the following parameters are constant - orientation, length of the strand, width and number of nucleotides. These double-stranded molecules are asymmetrical, with the two disjoint strands intertwined with each other, connected by means of hydrogen bonds.
Answer:
b, d
Explanation:
a, may be right since mutaion does benefit species in certain ways but since it's specifically saying fatal the a is not right.
b, because even though it doesn't happen often, 2 diverse species might interbreed if a survival or specific situation is given.
d, natural selection kill of those weak and helps the strongest survive by making genetic modifications throughout the generations going from one species to a completely different one in years.
Answer:
part 1- polymers part 2- monomers
The answer is <span>a. Each gene is at the same locus on both chromosomes.
Since e</span><span>ach gene is at the same locus on both chromosomes, they are able to pair correctly before they separate in meiosis. They never produce identical phenotypes. Also, the genes and alleles on the homologous chromosomes are not identical. </span>
Answer:
Force, mass and acceleration
Explanation:
I'm assuming that you meant three blanks in a row
