The single-stranded DNA is revealed and ready for transcription as soon as the RNA polymerase and its related transcription elements are in place. Afterwards, RNA polymerase will begin to move down the DNA template strand in the 3' to 5' direction, and as it does so, it ties together interrelated nucleotides. This action makes a new strand of mRNA that is arranged in the 5' to 3' direction because of complementary base-pairing. More nucleotides are affixed to the mRNA as the RNA polymerase continues down the strand of DNA, therefore building a developing longer chain of nucleotides. Which is called elongation.
I’m pretty sure number 1? I’m not sure though sorry
The correct answer is option (A) abundance of collagen fibers.
Bones are a type of supportive connective tissue forming an integral part of the skeleton. Bone tissue is made up of the different types of bone cells embedded in a matrix.
Bone matrix is mainly composed of the collagen fibres, also known as the ossein. They are fibrous protein units linked together rendering elasticity and improving fracture resistance. Collagen fibres are long, very flexible with a high tensile strength and resist stretching. They impart the characteristic resilience and strength, allowing it to withstand strong tension in case of bones, tendons, ligaments.
