Answer:
English:
RNA and DNA are polymers made up of long chains of nucleotides . A nucleotide is made up of a sugar molecule (ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen base. The bases used in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T).
Spanish:
El ARN y el ADN son polímeros formados por largas cadenas de nucleótidos. Un nucleótido está formado por una molécula de azúcar (ribosa en el ARN o desoxirribosa en el ADN) unido a un grupo fosfato y una base nitrogenada. Las bases utilizadas en el ADN son la adenina (A), citosina (C), guanina (G) y timina (T).
Well we have to say that It does not show that photosynthesis consists of many separate reactions.Have in mind that the simplified chemical reaction equation of photosynthesis is: <span>6CO2 + 6H2O ------> C6H12O6 + 6O<span>2. The problem is that this equation doesn't show the many other reactions involved in photosynthesis, including the the two important components, the light and dark cycle. I hope this is something very useful for you</span></span>

As the cap helps it to move around while the tail prevents enzymes from eating the RNA
Answer:
a. Bands at 1kb, 6kb and 8kb
Explanation:
The EcoRI and BamHI are the restriction enzymes which cut the DNA sequence especially a plasmid at specific sites called the restriction sites.
The restriction enzymes produces bands of specific length therefore these restriction enzymes are used to estimate the approximate length of the DNA.
In the given question, the
1. EcoRI- produces two strands of 7 kb and 8 kb
2. BamHI- produces two strands of 1kb and 14kb
This shows that the length of DNA sequence is 15kb
But when the DNA strand are digested with both the enzymes simultaneously then it will produce three bands as:
i) 14 kb can be broken down in 2 bands of 6 kb and 8 kb
ii) 1 kb band is already produced by the Bam HI.
This shows that 1+6+8= 15 kb
Thus, Option-A is correct.
