Which structural characteristic is seen in RNA but not in DNA? double strands a single strand chains of nucleotides a helical shape

Answers

Answer 1
Answer: The structural characteristic seen in RNA but not in DNA is a single strand. RNA and DNA are macromolecules made up of nucleotides organised in chains. DNA has double strands organised in a helical shape. RNA usually consists of a single strand which is not characteristic for DNA.
Answer 2
Answer: The answer is single strand

The sequence of an mRNA transcript is UGGCACUCCAG. What will be the sequence of the template DNA strand from which it was synthesized? A. UGGCACUCCAG
B. ACCGTGAGGTC
C. ACCGUGAGGUC

Answers

The sequence of an mRNA transcript is UGGCACUCCAG. ACCGTGAGGTC will be the sequence of the template DNA strand from which it was synthesized. Thus, the correct option is C.

What is mRNA transcript?

An mRNA transcript is defined as a single strand of RNA which capture the information contained in a gene.  mRNA transcript as a portable gene in which smaller and more mobile than the DNA sequence that it is built from, but contains the same information.

DNA base pairs in under normal circumstances, the nitrogen containing bases adenine (A)  always pair with thymine (T), and cytosine (C) and guanine (G) pair together.

All of the following are positive aspects of PACs EXCEPT?A. Members of PACs have access to candidates and parties.

B. PACs allow their members to support a range of candidates with a single contribution.

C. Candidates receive contributions from so many PACs that the effect of any single PAC is diluted.

D. PACs allow organizations to form a close connection to the legislators they support.

Answers

The correct answer is option C, Candidates receive contributions from so many PACs that the effect of any single PAC is diluted.

Reason -

Different parties that contribute to a certain candidate assumes to at least have a recognition to their contribution but since there are several donors (big or small), usually the donors with small amount of donation get neglected and the effect of their contribution is felt diluted. This seems to generate a negative aspiration in the donor.

Which kingdom(s) include organisms that are autotrophic or heterotrophic?

Answers

Kingdom Fungi. Mostly are single celled bacteria, they emit sunlight by means of photosynthesis that allows them to make food for themselves and also they have another food serve except for the sunlight and eats some single cell organism and that would call them as heterotrophic
