Answer:

(2) sequence of bases in a section of a chromosome

Explanation:

DNA is the part of chromosome which is responsible for the synthesis of proteins. DNA has sequence of bases and it acts as a template for the synthesis of an RNA molecule through the process of transcription. An RNA (mRNA) too has sequences of bases named as codons (triplet of nucleotides) which are responsible for the incorporation of specific amino acids corresponding to only those codons to form a protein molecule. The process of protein synthesis is known as translation.

Hence, a DNA decides which kind of protein will be synthesized in the body. So if the sequence of bases in a section of a chromosome or DNA is altered then the protein composition will not remain the as earlier and a new type of protein will be synthesized.

The answer is 2. An alteration in the DNA would cause an alteration in the mRNA which is what ribosomes use aa information to produce proteins. So if the message is changed, the product will therefore change

Answer:

A. Population growth is decreasing

-2

+4

-10

Compare the sugar-phosphate arrangement in the backbone of the DNA from the plant, the manmal and the bacterium. Are there any d
eimsori [14]

Answer:

No, there are no differences

Explanation:

Deoxyribonucleic acid (DNA) is a molecule composed of two polynucleotide chains that interact together in order to form a double helix. This molecule (DNA) carries the genetic instructions that make each species unique. In DNA, each polynucleotide chain is composed of nucleotide monomers: a nucleotide is composed of a deoxyribose sugar attached to a phosphate group and one nitrogen-containing base (i.e., adenine, thymine, guanine and cytosine). This basic structure is the same among different species, and, therefore, genetic differences between different groups (in this case, animals, plants, and bacteria) are caused by differences in the nucleotide-base sequences of their DNA molecules.

The sympathetic chain ganglia are a series of clusters of neuron cell bodies linked by bridges of ________
BabaBlast [244]

Answer:

b. axons  

Explanation:

The Peripheral Nervous System consists of nerves and ganglia. Nerves are nothing more than bundles of parallelly arranged nerve fibers surrounded by connective tissue. Each of these fibers is formed by an axon and the sheaths surrounding it. The ganglia, in turn, are accumulations of neurons, which usually form spherical structures, are located outside the central nervous system and are also linked by axons bridges.
