Describe how the folded structure of a peptide chain and the stereochemistry of an l-amino acid illustrate the difference betwee
snow_tiger [21]

The configuration is a concept that is related to the order (poition) by which different substituents linked to the same central atom, in the case of amino acids, around the central carbon atom. So, amino acids can be divided in two groups, L- and D- forms, analogous to left-handed and right-handed configurations.  

On the other hand, protein folding (folded structure of peptides) is the physical process by which a protein chain acquires its conformation (3D structure) that is usually biologically functional.

PLEASE HELP!! im despratte
Alex73 [517]

Answer:

Template strand = complementary strand

GCA AG = CGT TC

TTA CG = AAT GC

GAT AC = CTA TG

CGG AT = GCC TA

DNA strand = mRNA strand

CGA TT = GCU AA

GCT TA = CGA AU

GCA TC = CGU AG

TTC AT = AAG UA

It is more important for DNA replication to be exact than transcription or translation because any error that occurs during DNA replication if not repaired will become permanent and will be transferred to the next generation.

Explanation: In DNA base pairing, G pairs with C and T pairs with A. But in RNA base pairing, G pairs with C and U pairs with A. DNA contains four bases G, C, T and A while RNA contains four bases G, C, A and U.

At what levels do biologists study life?
andriy [413]
Biologist study life to the extent to which they can uncover, unearth and investigate unseen, latent and concealed life forms that are still many in number, these crawling and under the water creatures. And in experimental sense, many biologists are guided by the ethics in researching life forms. This is to protect and inhibit other biologist in killing thousands of these living organisms and prevent them from becoming extinct. Remember that biologists or any other scientists study because of knowledge and to contribute to the scientific world of making the ecosystem including us into a much better and cultured place and not the opposite.

Hence, there are non-experimental and experimental approaches which are all subject to ethics. In exploring life forms, it is quite unlimited but studying life forms in experimental sense, it is somehow depends on the number of species that the biologists’ study.

The DNA of a prokaryote is arranged in a single coiled chromosome located in a region called the ____________ . Some prokaryotes
Varvara68 [4.7K]

Answer:

1. Nucleoid

2. Plasmid

Explanation:

Prokaryotes are groups of organisms characterized by the lack of a membrane-bound nucleus in their cell. Due to this, the genetic material (DNA) of prokaryotes are found naked i.e. not housed. The DNA of a prokaryote is arranged in a single coiled chromosome located in a region of the cell called NUCLEOID.

However, some prokaryotes e.g. bacteria carry genes on extrachromosomal pieces of circular DNA called PLASMID. Plasmids carry certain genes like antibiotic resistance genes.
