Need a better picture!! it’s really blurry and can barely read
Answer:
a) snRNA
Explanation:
The association of small nuclear RNA (snRNA) and some specific proteins forms small nuclear ribonucleoprotein complexes. Some complexes are spliceosomes, molecular machines -made up of a snRNA and about 80 proteins- that remove introns from pre-mRNAs via successive phosphoryl transfer reactions.
When you have atoms they can’t touch each other like the body can’t touch anything so no they won’t be solid
