Answer:
A DNA sequence codes for the same proteins in different species
Explanation:
All living organisms store their genetic information in DNA (genetic material). The manner through which information in the genes are encoded is the GENETIC CODE. The genetic code comprises of all the codons that specifies amino acids in living organisms. The genetic code has several characteristics, which includes that the GENETIC CODE IS UNIVERSAL
The genetic code is said to be universal because all known living organisms use the same genetic code to encode their genetic information. This means that a DNA sequence codes for the same proteins in several different species. For example, codon AUG encodes the amino acid METHIONINE in every living organism.
Answer:
The correct answer will be option-B.
Explanation:
The plant tissues are composed of three types of cells: parenchyma, collenchyma and sclerenchyma.
The parenchyma and collenchyma remain alive at their maturity but sclerenchyma loses their protoplasm and become dead. These cells deposit lignin in their secondary walls and form hard tissues of the plant-like hard shell of a coconut. Sclerenchyma provides mechanical strength to the plant.
Thus, Option-B is the correct answer.
Answer:
C. Prohase 1
Explanation:
It is during prophase 1 of meiosis that crossing over occurs before tetrads or homologues pair of chromosomes are alligned across the equator of metaphase 1. In Meiosis 11, only the sister chromatics will be left or remain and the homologues pair of chromosomes would be moved to separate cells.
Answer:
C - Detritivore
Explanation:
A carnivore is a meat eater, an omnivore is a plant and meat eater, and a herbivore is a plant eater, which leaves C.
Answer:B) progress towards the replication fork.
Explanation:
Replication fork is a point on the parental DNA where the DNA is being unwound and separated; and the separated strands are being replicated. Synthesis of a new DNA strand occurs in a 5' -> 3' direction, as the DNA strand serving as the template is read from its 3' -> 5' direction. During replication, two strands of DNA are synthesized: The leading strand is synthesized continuously in the same direction as the replication fork movement while the lagging strand is synthesized discontinuously in the direction opposite to the direction of fork movement, that is, towards the replication fork. The lagging strand is synthesized in short fragments known as Okazaki fragments.
