Answer: Option A.
Achondrogenesis
Explanation:
Sonographic findings of severe micromelia, decreased or absent ossification of the spine, macrocephaly, and micrognathia are conditions of Achondrogenesis because
Achondrogenesis is a genetic disorder that is as a result of mutations in gene SLC26A2 which is responsible for cellular transport proteins that is needed for the growth and development of bones and cartilage. This condition lead to malformation of bones and cartilage and it is characterized by short limbs, small body, narrow chest ,prominent abdomen,underdeveloped lungs,lack of ossification in the spine and pelvis, prominent head, small chin e.t.c.
It is a condition that affects infants.
The major treatment is pallative care in which the doctor have to reduce pain stress of bones and cartilage and also genetic councellling.
Hairpin like structures are formed in both DNA and RNA but are common in RNA than in DNA. This is because DNA can be double stranded or single stranded while RNA is generally single stranded structure that can be double stranded only when it forms a hair pin like structure.
The features of hairpin structure in RNA are as follows:
1. This structure is a building block of many secondary structures of RNA.
2. The termination sequence during transcription also forms a hairpin loop like structure.
3. tRNA also forms a hairpin loop like structure and helps in the process of translation.
