The answer to your rather difficult question is paper. only certain trees make gum rubber, only certain trees make syrup and none of them make turpentine( an extremely flammable substance. the only thing you can get from almost every tree is paper.
Answer:
a) Particular codons are generated in predictable ratios with random RNA polymers containing specific ratios of different nucleotides.
b) Poly(A) RNA directs the synthesis of only polylysine in vitro.
d) The codon table was completed by using RNA polymers of defined sequences.
Explanation:
A polynucleotide molecule is defined as the biopolymer which is composed of thirteen nucleotide monomers or more monomers which is covalently bonded in the chain.
While using the synthetic polyneuclitide in the cracking of the genetic code, the translation of a that results in synthesis of the poly-lysine in the lab.
Some of the particular codons are produced by some specific ratios of a different nucleotides. This can be present in the different RNA polymers. Codon table includes the RNA polymers that contains nucleotides in some specific ratios.
Thus, the options (a), (b) and (d) are correct.
<span>The dominant stage in gymnosperms is saprophyte. Gymnosperms, like all vascular plants, have a life cycle that is saprophyte-dominant

Complete question:
The movement of auxin from the apical to basal sides of immature leaf cells and toward the xylem and phloem of the stem is an example of _____ transport.
polar
trophic
paraxial
bidirectional
Answer:
Polar
Explanation:
Auxin is one of several plant hormones. It is a group of several natural and synthesized plant hormones. Auxin is mainly produced in the apical meristem of the shoot. The synthesized auxin in shoot meristem moves downwards along the axis of shoot and root. Since this movement occurs in one direction only, it is also called unidirectional or polar movement. It is always transported downwards. Auxins are also produced in young leaves and seeds.
