What alternative form of genes do nucleic acids have that allows them to offer variability?
inna [77]

The answer to the above question is alleles.

<h3>What are Alleles?</h3>

The two nucleic acids in living things that are employed for conveying and storing genetic information are RNA and DNA. The genetic material in living things is called deoxyribonucleic acid (DNA), and it contains sections coding for beneficial proteins and products as well as carrying genetic information from one generation to the next. These chunks are referred to as genes.

However, genes also have a different form that is in charge of the genetic diversity in the qualities they are coding for. Allele refers to a gene's alternative or variant version. In a diploid creature like the human, each trait is encoded by genes that include contrasting pairs of alleles, allowing variation for that specific trait, i.e. two alleles for each gene. For instance, a gene with two alleles that codes for one of the human height traits includes the short variety (t) and the tall variety (T).

What are two diffrences between replication and transcription?
Ghella [55]
Replication - The action of copying or reproducing something.
DNA replication of producing two identical replicas of DNA from one original DNA molecule.

Transcription - First step to gene expression, in which a particular segment of DNA is copied into RNA (especially mRNA) by the enzyme RNA polymerase. Both DNA and RNA are nucleic acids, which use base pairs of nucleotides as a complementary language.

1.) Transcription involved both DNA and RNA, whilst replication only involves DNA.
2.) Replication uses two identical replicas of DNA, whilst transcription is copied.

Hope I helped.

<h2>a DNA double helix</h2>

Explanation:

  • Deoxyribonucleic acid is made up of two chains. A double helical structure is formed when two chains coil around each other.This double helical structure carry genetic information for the growth, reproduction, development and functioning of an organism.
  • The nucleic acid such as DNA and RNA are one of the major types of macromolecules which are necessary for all life forms.
  • The nucleotide is made up of one of four nitrogen containing nucleobases such as Adenine, Guanine, Cytosine and Thymine, Deoxyribose sugar and a Phosphate group.
