Question

1. what are the main functions of nucleic acids? store and transmit genetic info. 30. how many strands make up rna? 1 how many strands make up dna? 2 31. list the three types of rna and the structural shape of the rna in the table below. type of rna: m - rna, r - rna, t - rna shape: 32. list the functions of the following nucleic acids. a. dna: store genetic info b. rna: protein synthesis

Explanation:

1. Nucleic acids store and transmit genetic information. DNA has two strands and RNA has one strand in general.
2. RNA has one strand. DNA has two strands.
3. The three types of RNA are mRNA (messenger - RNA), rRNA (ribosomal - RNA), and tRNA (transfer - RNA). mRNA carries genetic information from DNA to ribosomes for protein synthesis, rRNA is a component of ribosomes, and tRNA brings amino acids to the ribosome during protein synthesis. The shape of mRNA is a single - stranded linear molecule, rRNA is part of the ribosome's complex structure, and tRNA has a clover - leaf shape.
4. a. DNA stores genetic information and is involved in replication and transcription to pass on and use the genetic code. b. RNA is involved in protein synthesis. mRNA carries the genetic message, rRNA is part of the ribosome machinery, and tRNA transfers amino acids.

Answer:

1. Main functions of nucleic acids: Store and transmit genetic information. Strands in RNA: 1. Strands in DNA: 2.
2. Strands in RNA: 1. Strands in DNA: 2.
3. Types of RNA: mRNA, rRNA, tRNA. Shape of mRNA: Single - stranded linear. Shape of rRNA: Part of ribosome structure. Shape of tRNA: Clover - leaf.
4. a. DNA functions: Store genetic info, replication, transcription. b. RNA functions: Protein synthesis (mRNA - carry message, rRNA - part of ribosome, tRNA - transfer amino acids).
