Answer:
The cell wall gives the plant stability
Explanation:
Answer:
Valine-Leucine-Proline-Lysine-Histidine
Explanation:
The central dogma of biology is the process by which DNA is used to synthesize RNA and subsequently amino acid sequence (PROTEIN). The processes of transcription and translation is used in gene expression. Transcription is the process whereby the information encoded in a DNA molecule is used to synthesize a mRNA molecule. Transcription is catalyzed by RNA polymerase enzyme, which uses complementary base pairing rule i.e Adenine(A)-Thymine(T), Guanine(G)-Cytosine(C) pairing.
N.B: Thymine is replaced by Uracil in the mRNA
For the above DNA sequence: CAC GAC GGA TTC GTA, the mRNA sequence will be: GUG CUG CCU AAG CAU
Translation is the second process of gene expression which involves the synthesis of an amino acid sequence from an mRNA molecule. The mRNA is read in a group of three nucleotides called CODON. Each codon specifies an amino acid (see attached image for genetic code)
Based on the attached genetic code, an mRNA sequence: GUG CUG CCU AAG CAU will encode an amino acid sequence: Valine(Val) - Leucine (Leu) -Proline (Pro) -Lysine (Lys) - Histidine (His).
GUG specifies Valine amino acid
CUG specifies Leucine amino acid
CCU specifies Proline amino acid
AAG specifies Lysine amino acid
CAU specifies Histidine amino acid
Answer:
4. The correct pathway for the flow of electron during photosynthesis is mentioned in option D.
> <em>NADP </em>> <em>Calvin cycle.</em>
- Electron is first provided to the photo-system II by the phtolysis of water.
- Then it is passed to photo-system I with the help of plastoquinone (PQ) and cytochrome
. - Finally, electron from the photo-system II is used to reduce NADP to NADPH.
- NADPH and ATP are used in light independent phase or Calvin cycle to synthesize carbohydrate from carbon dioxide.
5. The correct answer is B.) photosynthesis.
- Photosynthesis is the process by which green plants synthesize glucose or carbohydrate from carbon dioxide and water in presence of sunlight and chlorophyll.
- In light independent phase of photosynthesis, it requires ATP and NADPH in order to synthesize food.
- Lastly, oxidation or breaking down of glucose releases energy and photosynthesis is a anabolic process instead of catabolic one.
This means having no charge
A DNA molecule consists of two strands of nucleotides twisted together to form a double helix. The sugar-phosphate backbone is found on the outside of this helix and the bases are found braching towards the middle. Hydrogen bonds join the thenitrogenous bases and hold the two strands together.
Therefore your answer is sugar and phosphate.
