Answer:

D-DNA molecule

Explanation:

The process of copying the sequence of  DNA nucleotide  sequences to the mRNA is called   Transcriptions. It  is the  first stage in gene expression   for protein synthesis, and<u> it involves the unwinding of the DNA double strands  molecules  by enzyme</u><u> </u>DNA Helicase into two  free strands,(by melting the hydrogen bonds between organic  bases), a process   initiated by the binding of enzymes RNA Polymerase to  the promoter sites on the DNA  template; the alignment of the mRNA  nucleotides on the  single DNA template strands in 3'-5  direction; the formation of  hydrogen bonds between the organic bases  of the template DNA  and   that of the messenger RNA single strands,(  and phosphodiesterbonds  within RNA nucleotide ), to form DNA-RNA complex.

The copying is done in  complimentary anti parallel fashion;5'-3' prime. direction.

 The  hydrogen bonds, between the bases  DNA-RNA complexes breaks,and  the releases  the mRNA  which  exists through the nuclear pores.Thus  this <u>leads to copying of the the coded messages as seqeunce of DNA , from the DNA to the mRNA for gene expressions.</u>

construct a dichotomous key which can be used to identify the five antelopes shown in figure 1.1 use only visible features.​
Bas_tet [7]

The dichotomous key used to identify the antelopes might be based on the presence/absence of certain muscles, weight, etc.

<h3>What is a dichotomous key?</h3>

A dichotomous key is a system to classify species and/or taxonomic groups by using two different choices.

For example, the presence/absence of certain physical features can be used to identify the antelopes.

Moreover, the threshold in certain features such as weight/height can also be used to classify species.

What is the relationship between a sac fungi and the making of bread
Karolina [17]

Answer:

The sporangium matures and releases spores into the air. There are about 30,000 species of ascomycetes, members of the division ascomycota, commonly called sac fungi. The most well known members of this group, yeasts, are used to make bread rise and to carry out anaerobic fermentation in brewing alcohol.Apr 17, 2006
