Salsk061 [2.6K]

Answer:

a. the RNA polymerase undergoes abortive initiation prior to promoter clearance

Explanation:

In eukaryotes the 3' end of the mRNA is polyadenylated to protect the mRNA from degradation.

In eukaryotes, a modified guanine cap is added to the 5' end of the mRNAd to protects the transcript from being broken down.

Most bacterial RNA transcripts do not undergo splicing.

The nucleosome is the basic unit of chromatin repeat in eukaryotes.

What is shown in the imagine <br> prokaryote<br> eukaryote<br> chloroplast<br> mitochondrion
m_a_m_a [10]

"Prokaryote" is shown in the given image.

Answer: Option A

<u>Explanation:</u>

A prokaryote is a single-cell organism which is deficient in a membranous nucleus, mitochondria, or any other membranous organs. Prokaryotes are categorized into two domains: Bacteria and Archaea. At the third domain: Eukaryota, species with nuclei and organelles are located.

The asexual prokaryotes reproduce without fusion of gametes. They are considered as first living organisms. In the prokaryotes components like proteins, DNA and metabolites, overall the intra-cellular water-soluble components are enclosed by the cell membrane as situated together in the cytoplasm, rather than in separate cellular compartments.

An mRNA sequence reads: GAA/GCU/AUA/CUA/UGU. What would the effect on the amino acid be if the second codon read GCA instead, an
Murrr4er [49]

Answer:

D) Silent mutation on second codon, third amino acid changed from ILE to ASN.

Explanation:

Silent mutations are usually point mutation where you change one nucleotide. Since, the nucleotide changed is the third position, it does not affect the protein being manufactured (it will still put the amino acid Ala) [look up the codon redundancy on youtub.e to understand how awesome nature is!]

On the other hand, the other mutation introduced is Missense mutation where a different Amino acid is added due to change in codon (goes from ILE to ASN).
