NADH is also used by cells when making certain molecules. Based on your knowledge of the role of NADH in cellular respiration, w

chubhunter [2.5K]

Answer:

b. reducing molecules

Explanation:

Nicotinamide adenine dinucleotide (abbreviated NAD +, and also called diphosphopyridine nucleotide and Coenzyme I), is a coenzyme found in all living cells. The compound is a dinucleotide, as it consists of two nucleotides linked through their phosphate groups with a nucleotide that contains an adenosine ring and the other that contains nicotinamide.

In metabolism, NAD + participates in redox reactions (oxidoreduction), carrying electrons from one reaction to another.

Coenzyme, therefore, is found in two forms in cells: NAD + and NADH. NAD +, which is an oxidizing agent, accepts electrons from other molecules and becomes reduced, forming NADH, which can then be used as a reducing agent to donate electrons. These electron transfer reactions are the main function of NAD +. However, it is also used in other cellular processes, especially as a substrate for enzymes that add or remove chemical groups of proteins, in post-translational modifications. Due to the importance of these functions, the enzymes involved in the metabolism of NAD + are targets for drug discovery.

Where does your organism live? Describe its habitat.

Simora [160]

Habitat, place where an organism or a community of organisms lives, including all living and nonliving factors or conditions of the surrounding environment. A host organism inhabited by parasites is as much a habitat as a terrestrial place such as a grove of trees or an aquatic locality such as a small pond.

True-breeding flies with red eyes and long wings were crossed to flies with white eyes and miniature wings. All F1 offspring had

Lelu [443]

The question is incomplete. Complete question is as follows :

What is/are the phenotype(s) of the recombinant offspring of the F2 generation?

Parental generation: True-breeding flies with red eyes and long wings were crossed to flies with white eyes and miniature wings. All F1 offspring had red eyes and long wings.

The F1 female flies were then crossed to males with white eyes and miniature wings. The following results were obtained for the F2 generation:

129 red eyes, long wings

133 white eyes, miniature wings

71 red eyes, miniature wings

67 white eyes, long wings

Answer:

Red eyes, miniature wings and white eyes, long wings

Explanation:

In absence of linkage parental and recombinant offspring are produced in equal number. When there is linkage crossover does not take place in expected frequency so recombinants are produced in lesser number than parental type offspring.

Here in F2 generation red eyes, miniature wings and white eyes, long wings are produced in lesser number (71 and 67). Also the original parents had red eyes, long wings and white eyes, miniature wings. Hence, Red eyes, miniature wings and white eyes, long wings are the phenotype of the recombinant offspring of the F2 generation.

How do you change dna to rna to amino acids

yanalaym [24]

This can be done through the Transcription and Translation process.

Long story short: DNA -> messenger RNA (mRNA) -> amino acids -> polypeptide chain -> protein

Step 1: Transcription
1) DNA loop is open
2) RNA polymerase (enzyme in nucleus) catalyze reaction of “unzipping” DNA
3) free RNA nucleotides in nucleus will be added to that strand of DNA
4) messenger RNA moves across nuclear membrane to cytoplasm (our nucleus)

Step 2: Translation
1) messenger RNA attaches to ribosome
2) mRNA determines which amino acid to place on protein
3) uses codons (triplet) on mRNA. Codon on mRNA and anticodon on tRNA have to match, which places true amino acid in ribosome, then it detached and finds another amino acid in cytoplasm.
4) “AUG” starts translation, and keeps going until reaching “stop codon”.
5) completed polypeptide chain results to protein being synthesized

Your teacher should explain this process more in depth hopefully
