Question

1. dna passes information to rna during the process of —

a transcription
b active transport
c regeneration
d osmosis

1. which of the following must occur before dna replication can take place?

a translation of dna into amino acids
b separation of the dna molecule into codons
c transformation of dna into rna
d separation of the dna double helix

1. if a plant that is homozygous tall and wrinkled is crossed with a short, wrinkled plant, which percentage of genotypes would most likely be found in the first - generation offspring?

a 50% ttss, 50% ttss
b 100% ttss
c 100% ttss
d 50% ttss, 50% ttss

1. in dna, which of the following determines the traits of an organism?

a amount of adenine
b number of sugars
c sequence of nitrogen bases
d strength of hydrogen bonds

Explanation:

1. Transcription is the process where DNA passes information to RNA.
2. DNA double - helix must separate before replication can occur.
3. Homozygous tall and wrinkled (TTss) crossed with short, wrinkled (ttss) gives all Ttss offspring.
4. The sequence of nitrogen bases in DNA determines an organism's traits.

Answer:

1. A. transcription
2. D. Separation of the DNA double helix
3. C. 100% Ttss
4. C. Sequence of nitrogen bases
