The double-helix shape of DNA.
Nesterboy [21]3 years ago
4 0

Answer:

In 1953, Watson and Crick determined the double-helix composition of DNA, that is, the molecule comprising human genes. They found that the composition of DNA was a spiral of two strands of DNA or a double-helix polymer, each comprising a lengthened monomer chain, that is, the nucleotides wrapped around each other.  

The DNA, that is, a nucleic acid formed of nucleotides combined into chains or long strands with the help of covalent bonds. The nitrogenous bases present in the DNA are guanine, adenine, thymine, and cytosine.

A student analyzed a viral genome and found that the genome had the following nucleotide composition. 28% adenine 20% thymine 35
egoroff_w [7]

Answer: Option A) Double-stranded DNA

Explanation:

First, the presence of thymine infers that the genome is DNA.

Then, to determine whether it is single or double stranded, we check if the sum of all nitrogenous bases is equal to 100%

A + C + G + T = 100%

28% + 35% + 20% + 17% = 100%

Since all bases makes 100%, we can conclude that the genome is a double stranded DNA

In messenger RNA, each codon calls for a
olganol [36]

Answer: c) amino acid

Explanation: A codon is an mRNA sequence which contains three nucleotides that codes for a particular amino acid. The codons on the mRNA are read by the ribosome during translation and the amino acid coded for by each codon is used to make a protein. There are 64 different codons in existence, each amino acid is coded for by at least one codon. Some amino acids have more than one codon. For example, the amino acid Leucine is coded for by six codons: UUA, UUG, CUU, CUC, CUA and CUG while the amino acid phenylalanine is coded for by two codons: UUU and UUC.

When calculating the rate of photosynthesis, why was it necessary to subtract the rate of O2 change in the light minus the rate
Nezavi [6.7K]

Answer:

plants process oxygen for respiration as an aerobic organism and also produces it, light can regulate this metabolism, which means that in the presence of light oxygen generation occurs as well as consumption and when there is darkness only consumption will occur Thus, when calculating the amount of oxygen that a plant produces during photosynthesis, it will be necessary to subtract the oxygen it consumes, from which it is deduced that the rate of oxygen consumption will not have variations and will be the same in the day and in the At night, so the change of oxygen in the dark is subtracted with the change of volume of oxygen in the light phase
