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.
Answer:
volcanic eruption
Explanation:
its just not necessary :)
Theoretically it is the Chargaff's rule which entails that the ratio of purines and pyrimidines are 1. So following that rule you can solve this question.
G (purine) = C (pyrimidine) and
A (purine) = T (pyrimidine)
So G + C would be 28% and hence
A +C would be 72% i.e. 36% each.
Please note that their are certain modified bases besides these four are also there including methyl Cytosine, Methylated Adenine. But htese modification does not violate the Chargaff's rule and they follow standard Watson Crick base pairing.
Answer:
A. supplementary motor cortex; premotor cortex
Explanation:
The supplementary motor cortex, also known as the supplementary motor area (SMA), is an area of the cerebral cortex located anterior to the premotor cortex. This area (SMA) is involved in the execution of complex and rapid sequential movements (e.g., typing). Moreover, the premotor cortex is an area of the motor cortex located between the primary motor cortex and the prefrontal cortex. This area (premotor cortex) is activated during motor tasks including, among others, spatial and sensory guidance of movement.
