Which of the following pairs of base sequences could form a short stretch of a normal double helix of DNA?
11Alexandr11 [23.1K]

Answer:

D) 5'-ATGC-3' with 5'-GCAT-3'

Explanation:

In a double helix DNA, adenine always pairs with thymine and cytosine pairs with guanine. Also, the two strands of a double helix DNA are antiparallel, that is, the 5' end of one strand lies opposite to the 3' end of another strand.

Therefore, a DNA strand with base sequence 5'-ATGC-3' would have a complementary strand 5'-GCAT-3'.

Double stranded DNA: 5'-ATGC-3'                                          

                                      3' TACG 5'

DNA polymerase has multiple mechanisms for editing and error correction whereas the capacity for error correction in RNA polymer
BigorU [14]

The given question is incomplete as the option are not provided however, the correct options are as follows:

Defective proteins are often degraded quickly, making their effects temporary.

Single amino acid substitutions caused by errors in mRNA transcription would not affect protein function.

Unlike DNA mutations, mRNA transcripts have short half-lives and are not inherited across many generations.

Degradation of defective proteins activates mRNA repair pathways RNA polymerases synthesize many transcripts per gene, so only a small fraction of RNA transcripts would have errors.

ch mRNA molecule is only translated once and then degraded

Answer:

The correct answer is - statements 1, 3, and 4.

Explanation:

DNA polymerase is the enzyme that is responsible for the production of the new DNA molecule and any mutation in this enzyme that will inhibit the DNA repair process which affects future generations.

RNA polymerase is an enzyme that is responsible for the transcription of DNA to mRNA and any error-prone mRNAs have chances of degradation. Error in DNA replication is from generation to generation as it is inherited

The process of transcription is quick.

Property of water that makes transpiration to occur
FrozenT [24]

Answer:

cohesion

Explanation:

One of water's most distinctive properties is cohesion—that is, the tendency of water molecules to "stick" to one another. In plants, this cohesion results in columns of water that stretch through the plant's xylem, from the roots all the way to the leaves.

Hope this helps:)

Which of the following is the amino acid that appears at the N-terminus of all newly translated prokaryotic and eukaryotic polyp
Elis [28]

Answer:

The correct answer is option second - methionine.

Explanation:

During translation, the initiator tRNA binds with a smaller subunit of the ribosome and this assembly bind to the start codon AUG at mRNA molecule in both prokaryotes and eukaryotes and then large subunit bind to this assembly and start polypeptide chain.

So, the first codon is AUG which is start codon and code for methionine in eukaryotes and fMeth in prokaryotes at newly translated prokaryotic and eukaryotic polypeptides at the N- terminus.

Thus, the correct answer is option second - methionine.
